Different embodiments of the present invention will be described in detail herein with reference to the accompanying drawings. In the drawings, like symbols generally define similar elements unless specifically described herein. The embodiments described in the embodiments, drawings, and claims are not intended to be limiting. Other embodiments and other changes may be made without departing from the spirit or scope of the invention. It will be understood that the aspects of the present invention, as generally described herein, and described in the drawings, can be arranged, substituted, combined, and designed in a wide variety of configurations, all of which are explicitly Consider a part of the invention.

definition

This is a definition of some terms and descriptions used herein. These terms and other terms appearing elsewhere in the present invention are used in accordance with the disclosure of the scope of the claims, unless specifically described.

"Abutment" or "arched tooth" means a tooth whose restoration or part thereof is trimmed. For example, an auxiliary missing tooth is used as an arch to secure an artificial tooth containing a missing edentulous space.

"Adjacent teeth" means that a tooth is located directly adjacent to or adjacent to a body tooth.

The "tongue surface" is the side surface of one of the teeth facing the tongue. The "cheek surface" is a side surface that faces the cheek and is generally facing away from the tongue surface. The "lip surface" is the side surface facing the lip and generally facing away from the front surface of the front teeth. "Proximal surface" means the two sides of the tooth facing the adjacent teeth. The "near midface" is one of the proximal surfaces and generally faces the center of the arch. The "far mid-face" is the other of the proximal surface and is far from the center of the dental arch.

The term "dressing" of a tooth means cutting, lowering, adjusting, ablating, and/or grinding the tooth to remove or eliminate a portion or portion of the tooth such that the trimming of the tooth is ready to mount the tooth. "Before trimming" or "not trimming" means a state in which the body of the tooth has not been finished trimming or is sufficient to prepare for the restoration of the tooth. Therefore, even if the teeth have been partially cut, lowered, adjusted, ablated, and/or grounded, if they are not yet ready to be joined to the specific jaws for attachment to the trimming teeth, additional cutting, lowering, adjustment, burning without the need for specific teeth Corroded or ground, it is still in the state of "before trimming" or "not trimming". When the teeth are trimmed to completion or completion, ie, "after completion", the trimming teeth can be joined to the particular portion of the jaws used to engage the trimming teeth without additional cutting, lowering, ablation, or grinding of the teeth. .

Terms that indicate direction or relative position, such as up, down, top, bottom, side, are only used for simplicity Easily identify specific features or make the above features easier to understand. This term is not intended to limit the particular orientation or location of the invention. For example, most of the embodiments disclosed in this application are described below for the teeth of the lower jaw. However, the embodiments or any claimed invention are not limited to the underlying teeth. Also, for example, the term "top" can sometimes be used to indicate that it is away from the gums, gums or roots, as opposed to limiting its absolute position. Those of ordinary skill in the art to which the invention pertains will understand that these terms are relatively natural and will be understood in the context.

To repair the teeth

In the traditional dental procedure used for repair, the patient's teeth are first trimmed prior to proper repair. In particular, the dentist and/or the dental operator first prepares the patient's teeth, creates an impression of trimming the teeth, makes an impression-based restoration, and installs the teeth on the patient's teeth. Figure 1 depicts trimming the teeth. A dentist (not shown) grinds or cuts the teeth 70 using the hand piece 230 and associated dental drill 200. The amount or accuracy of tooth elimination depends largely on the skills or experience of the dentist's hands. Figure 2 depicts the trimming of the teeth 70 (the trimmed teeth) and the tampering 50 mounted on the teeth 70. The tooth 70 in Figure 2 indicates that it is over-adjusted and that it is cut to be rough or unsmooth. This result is not unusual when the dentist does not have good hand techniques. Even if the dentist has very good hand techniques and experience, the trimming of the dental restoration is usually cut into the dentin in the enamel, which can cause damage to the pulp tissue or nerve cells.

Manufacture of previous techniques to repair teeth

In an embodiment, the oral cavity is generally provided for the trimming of the teeth, and the restoration can be installed immediately after trimming. In an embodiment, the oral cavity can be mounted to the trimmed teeth without the need to adjust the trimmed teeth to conform to the trimming teeth. In an embodiment, trimming the teeth would require a shape or configuration that is substantially reinforcing and of high accuracy. If the dressing is in a good reinforcement or corresponds to the shape of the complexion to be trimmed, it is possible to repair the teeth without further adjustment, cutting or grinding. of.

When relying solely on the skills and experience of the dentist's hand, it is difficult to repair the teeth without further adjustments in order to meet the requirements for repair. In an embodiment, a dental dressing guide is described. In an embodiment, the dressing guide guides the movement of the cutting tool such that the dental drill (ie, the hand piece) follows a predetermined route or trajectory, so that the tooth can be cut into a gauge without relying on the hand technique of the dentist. painting. In an embodiment, the dressing guide and the trimming device associated with the dressing are such that the trimming of the teeth using the dressing guide does not require further trimming of the teeth or adjustment of the teeth to cause a good fit to be repaired. Trim the teeth.

Oral procedure

In an embodiment, a new oral procedure prior to dressing the teeth can be developed using techniques that provide oral healing. An example of an oral procedure is now discussed with reference to Figure 105. When the dentist or dental operator examines the patient's teeth and confirms that oral repair is needed. The dentist developed a plan to repair the mouth. S100. Under the patient's consent to this plan, three-dimensional image data of the oral characteristics of the patient with the subject's teeth is needed. S200. The 3D image data is then used to design the intended trim image, which is the intended image of the trimmed body tooth. S300. Optionally, the cutting tool is designed to be trimmed. S400. Next, the trim is considered and decided to perform the desired trim image on the real tooth. S500. The structure of the dressing guide is designed under the decision of the dressing. S600. The oral procedure is then designed based on the expected trimming of the image. S700. With the current design, the cutting tool, the dressing guide and the tamper are manufactured. S620, S640 and S800. These manufacturing devices are then provided to the dentist. S900. The dentist uses a dressing guide and a cutting tool to trim the body teeth. S1000. During the dressing, the dentist is installed to repair the teeth. S1100.

Impression of the teeth before dressing

In an embodiment, the three-dimensional image data of the patient's teeth or oral morphology and features is trimmed to the main teeth. The body was obtained by repair. Next, the three-dimensional image data produces an oral cavity and a trim guide to trim the teeth to conform to a particular restoration. In one embodiment, the three dimensional image data is conveniently obtained using a three dimensional scanner. In another embodiment, when the three-dimensional scanner is not used, the three-dimensional image data is obtained by capturing a copy (impression) of the patient's oral characteristics, and the three-dimensional image data is obtained when the three-dimensional scanner is used for self-replication. .

When the patient visits the dentist's office or clinic, the dentist or dental operator examines the patient's teeth, for example, a dental restoration or recovery. Once the patient agrees to the oral cavity, the three-dimensional image information/data of the subject's teeth and the characteristics of the adjacent teeth are collected using a three-dimensional scanner or impression technique. The dentist does not cut or trim the body teeth until the 3D image data is obtained. In an embodiment, the oral characteristics of the scanned patient can be performed at a dentist's office, clinic, dental laboratory, or some other location. More preferably, the impression of the patient's oral characteristics can be taken at the dentist's office, clinic, dental laboratory or some other location. The conversion impression as 3D image data can be performed at any suitable location and by any suitable person.

Expected shape

In an embodiment, a CAD/CAM system can be used to perform three-dimensional image data to provide a desired trim shape that is the desired shape or image of the computer model of the trimmed tooth. The trimmed image is expected to describe the resulting shape of the tooth (with or without adjacent teeth or teeth) that can be obtained when impression finishing is established on the teeth. In an embodiment, it is contemplated that the trim shape or image may be based on three-dimensional image data and obtained using parameters that are trimmed. In an embodiment, most contemplated trim shapes or images may be obtained using different trim parameters. In an embodiment, an intended trim shape can be selected. Preferably, the trim shape is expected to be automatically generated by selecting specific appropriate parameters for trimming. In an embodiment, it is contemplated that the trim shape is provided in the three-dimensional image data and can be displayed in a display screen.

Embedded shaft

In accordance with an embodiment, when designing a dressing guide, a CAD/CAM system is used to perform three-dimensional image data (oral characteristics of the patient) to determine the channel of insertion (or proximity) towards the trimming of the teeth for installation. In one embodiment, in designing the desired trim shape, the 3D image data is evaluated to determine the preferred or arbitrary channel for the embedding of the mounting. In one embodiment, the preferred or any channel of the embedding has an axis that is embedded or approximated, wherein the direction of the retraction is suggested to move to restore and facilitate most of the fit between the teeth.

In an embodiment, the embedded channel or shaft is selected or determined such that when the desired trim shape is viewed along the embedded axis, no substantial cut can be found in the cut or adjusted side surface of the intended trim shape. In one embodiment, the embedded channel and shaft are selected or determined such that the cutting or adjustment of the teeth can be minimized such that when the desired trim shape is viewed along the inlay axis, there is substantially no cutting or adjustment to the desired trim shape. Side surface. In an embodiment, the embedded channel and shaft can be selected or determined such that the cutting or adjustment of the teeth can be balanced (without severe cutting on a surface) between the two or more surfaces to view the desired trim along the embedded axis. The shape can be cut to make, substantially without cutting or adjusting the side surface that is cut into the desired trim shape.

High degree of accuracy

In an embodiment, when viewed in the direction of the embedded determining axis (channel), there is no substantial cutting of the side surface of the intended trim shape. This can be accomplished by using a dressing guide designed to view the embedded decision axis. When relying on the dentist's hand technique, it is difficult to trim the teeth under the side surface that is not significantly cut to the teeth. In order to avoid significant cutting, the cutting of the side surfaces should result in a significant slope angle of the side surface that is greater than about 6° relative to the embedded axis.

In an embodiment, it may not be possible to trim the guiding device to allow for accuracy when relying solely on the skill of the dentist. Thus, the side surface of the tooth can be trimmed without significant cutting, even if the side surface is adjusted to have only a minimum slope (relative to the slope of the embedded axis). In one embodiment, because the dressing guide includes a form of a shaft containing a rotation of the drill to maintain an axis relative to the embedded constant With a guiding channel, a small slope is possible. The direction can also be maintained as the tool moves while cutting. For example, the axis of rotation and the embedded axis of the drill can be parallel when cutting. By cutting as explained above, an accurate cutting surface can be obtained.

In an embodiment, the slope angle of the side surface with respect to the embedded shaft is from about 0° to about 3°, although not limited thereto. In an embodiment, the sloped surface can have an angle greater than, for example, from about 3[deg.] to about 6[deg.] and from about 6[deg.] to about 15[deg.].

Dressing guide design

In an embodiment, the CAD/CAM system is permanently designed to trim the three-dimensional image data of the guiding device. In one embodiment, the trim guide is designed to trim and shape the three-dimensional image data of the shape or image based on the three-dimensional image data of the patient's oral characteristics. In an embodiment, the dressing guide is designed to conform to the body teeth used to trim and/or its adjacent teeth. In an embodiment, the dressing guide is designed to include features to assist, facilitate, and/or guide cutting, conditioning, grinding, ablating of the subject's teeth to meet the desired response.

Dressing guide design - in line with teeth

In an embodiment, the dressing guide is designed to have at least two sides and a top surface that interconnects the two sides. In an embodiment, the dressing guide comprises an interior space or a recess defined by the top surface and both sides. In an embodiment, the interior space and the recess are configured to receive at least one tooth. In an embodiment, the interior space or depression is configured to closely conform to at least one tooth. In an embodiment, the inner space or the inner surface of the recess is configured to engage a portion of at least one tooth. In an embodiment, the inner space or the inner surface of the recess includes features that at least partially reinforce the outer topography of at least one of the teeth such that the teeth conform well to the recess.

In an embodiment, the top surface covers, corresponds to, and/or faces the occlusal surface of the posterior teeth. In an embodiment, the top surface covers, corresponds to, and/or faces at least two occlusal surfaces of the teeth.

Dental drill

Referring to Figures 7-10, 12, 13, 24-43, and 88, the dental drill 200 has a handle 202, a neck 203, and a cutting head 204. The handle 202 is a portion that is fixed to the hand piece 230. The cutting head 204 is a portion that contacts the tooth to be cut. The neck 203 connects the cutting head 204 and the handle 202 and is the portion guided by the guide slot of the dressing guide 100.

In an embodiment, the dental drill 200 is made of tungsten carbide or stainless steel and is ground coupled to the cutting head 204. For example, diamond grinding can be used. In another embodiment of the invention, the cutting head can comprise a multi-cut edge instead of a grinding.

In an embodiment, the neck 203 conforms to and moves along the tool rail 120, which includes the shape of the guide slot discussed below. For the above purposes, please refer to Figures 38, 39 and 88, in an embodiment, The neck 203 has two spherical guiding protrusions 208, 210. As the dental drill 200 rotates and moves along the tool rail 120, the guide projections 208, 210 move along the grooves formed in the walls of the tool rail 120 discussed below. In some embodiments, the guide protrusions 208, 210 can be disc shaped. In other embodiments, the guide protrusions 208, 210 can be elliptical, tapered or trapezoidal in shape. In some embodiments, the guide projections 208, 210 are configured as part of the neck 203, but in other embodiments, the guide projections can be separated from the neck. For example, the rotating ring can be separately mounted on the neck 203 as a guiding protrusion.

Tool guide or channel

In an embodiment, the tool rail 120 is provided to guide the dental drill 200 to follow a predetermined path or trajectory. After the dental drill 200 is properly embedded in the tool guide 120 via the inlet aperture, the dental drill 200 can only move along a predetermined path. The dental drill 200 moves along the tool rail 120 and removes or cuts the teeth. In an embodiment, as shown in FIG. 66, the tool rail 120 includes a non-cut access channel 1202. The non-cut access channel 1202 is a portion of the tool rail 120 to guide the drill 200 to the position where the cutting begins. In some embodiments, the dental drill 200 does not cut teeth as it moves along the non-cut access channel. In an embodiment, the tool hole is located at a point near the tool guide that begins to cut, and the separate non-cut access channel may not be needed.

Cutting teeth along the tool rail

In an embodiment, the dental drill 200 may not cut teeth in any position along the tool rail 120. Although the dental drill 200 is cut at a particular location, it is determined by the radius of the dental drill 200 (the size of the cross-section) and the distance between the tool guide 120 and the surface of the tooth. Because the radius of the dental drill 200 can vary depending on the longitudinal shape of the dental drill, the shape of the dental drill also affects the cutting of the tooth.

In an embodiment, the distance between the tool rail 120 and the surface of the tooth can be defined by the distance between the vertical centerline of the tool rail 120 and the surface of the tooth, as shown in FIG. In an embodiment, ideally, the vertical centerline of the tool guide 120 conforms to the axis of rotation 201 of the dental drill 200, as shown in FIG. In some embodiments, the distance d between the axis of rotation 121, 201 of the dental drill 200 and the surface of the tooth is determined by the passage of the tool rail 120. Assuming that the dental drill 200 having a predetermined radius and shape is used, the depth of the cut can be changed according to the change in the distance d, and it is the portion where the tooth is cut. For example, although not shown in FIG. 6, in the embodiment, the teeth are not cut along the axis of the dental drill 200 that rotates 121, 201 further away from the teeth than the radius of the dental drill 200.

In an embodiment, the dressing guide 100 is designed such that the dental drill 200 cuts teeth along all points on the path of the tool rail 120. In an embodiment, the depth of the cut along the path can be configured to be nearly constant or vary greatly. In another embodiment, the dressing guide 100 is designed such that the dental drill 200 cuts the teeth while moving along a particular portion of the tool rail 120, but not along other portions. In an embodiment, the dressing guide 100 is designed such that a portion of its dental drill 200 moves without cutting the teeth and then a connecting portion of its dental drill moves while cutting the teeth. In some embodiments, the dressing guide 100 is designed such that a portion of it moves between the teeth of the teeth that do not require cutting the teeth or the intervention portion when cutting the teeth. In some embodiments, the dressing guide 100 is designed such that a portion of it moves between the dental drill movements or the interventional portion without cutting the teeth, without cutting the teeth. The different forms of the embodiments in this paragraph assume the use of a dental drill having a predetermined radius and shape.

Do not cut the occlusal surface

Referring to Figures 66-74, in an embodiment, the dressing guide 100 has two tool guides 120 for cutting the side surfaces of the teeth and the non-cut access channel. The first of the two tool guides 120 is for cutting the first molars, and the other is for cutting the first and second front molars. The bridge-like tamping 50 used in the described embodiments does not require cutting of the occlusal surface. Once the occlusal surface is not cut, the tool guides used to cut the occlusal surface are not required.

Limitation of the drill in the tool guide

Referring to Figures 39A, 39B, 69A and 69B, which show a cross section of the tool rail 120, in an embodiment, the tool rail 120 has two leading side surfaces 128 facing each other. The two guiding side surfaces 128 form a guiding slot. As the dental drill 200 enters the guide slot, the movement of the dental drill 200 is constrained and the dental drill 200 is guided along the tool guide 120. The distance between the guiding side surfaces 128, i.e., the width of the guiding slot, is limited to reduce the inclination of the neck 203 of the dental drill 200, but is large enough for the neck 203 to overcome friction and rotation. In the embodiment of the present invention, the tool guide 120 is shaped as a guide slot, but the present invention is not limited to the above embodiment.

In some embodiments, portions of the dental drill 200 enter the guide slot and become constrained by its movement, but other embodiments have a structure in which the hand member 230 is embedded and constrained by the guide slot of the tool to the guide 120. For example, in the embodiment shown in FIG. 126, the structure 2301 of the hand piece 230 is embedded and constrained by the guide slot. In contrast, the dental drill 200 is not constrained directly by the guiding slot. Preferably, although not shown, other embodiments may include the structure of the hand member 230 and portions of the dental drill 200 that are embedded and constrained by the tool rail.

Use at least two drills in the tool rail

In some embodiments, a single dental drill is used to cut the teeth, and in other embodiments at least two dental drills can be used to cut. For example, an embodiment having a thick portion for cutting, the first dental drill can be Some of the layers are cut along the tool rail 120 while the second drill can then move along the tool rail 120 to cut the remaining layers to obtain the final cut shape. In another embodiment of the invention, the first dental drill can perform a rough cut while the second dental drill can be followed by a fine cut.

In embodiments in which at least two dental drills are used, at least two dental drills enter the tool rail 120 via the same inlet. In another embodiment, referring to Fig. 124, the dental drill can be in the middle of the tool rail 120. In order to follow the above substitutions, an embodiment has an intermediate tool hole 124a, or an intermediate tool hole, formed in the middle of the tool rail 120. Although not described, some embodiments may have at least two intermediate tool holes in the tool rail 120, so it is possible to replace the dental drill at least twice. In an embodiment, first, the first dental drill is preselected into the tool rail and cut along the first portion 120a. Next, the first dental drill is removed via the intermediate tool hole 124a at the end of the first portion 120a. Next, the pre-selected second dental drill enters the tool rail via the intermediate tool bore 124a and cuts the teeth with the second portion 120b of the tool rail 120. Here, the first 120a and the second portion 120b of the tool rail 120 are not separated and connected to each other to constitute a single tool rail 120. Figure 125 is a flow chart of the above embodiment.

In an embodiment, the first portion 120a and the second portion 120b have different internal structures such that the first drill cannot move the first portion 120a along the second portion 120b. More specifically, the internal structure of the first portion 120a of the tool rail 120 reinforces the shape of the first dental drill, and the internal structure of the second portion 120b of the tool rail reinforces the shape of the second dental drill. In addition, the first dental drill and the second dental drill are relatively different as follows: the length of the neck 203, the thickness of the neck 203, the number of guiding protrusions 208, 210, the shape of the guiding protrusions 208, 210, and the guiding The dimensions of the protrusions 208, 210, and other considerations. The first 120a and the second portion 120b can also have different configurations corresponding to their opposing dental drills. Thus, in an embodiment, the first portion 120a may reinforce the first dental drill, but the second portion 120b may not reinforce the first dental drill, and only the second dental drill may enter and move along the second portion 120b. In other embodiments, the first 120a and second portions 120b of the tool rail 120 can have the same internal structure such that the first dental drill can pass through the intermediate tool aperture and along the second portion 120b.

Guide groove

Referring to Figures 39, 44, 69A, and 69B, in the embodiment of the present invention, each of the guide walls 128, 130 has guiding grooves 132, 134 and a guiding drill 200. The guide projections 208, 210 of the dental drill are embedded and move along their corresponding guiding grooves 132, 134. In some embodiments, the distance between the guide grooves 132, 134 via the tool rail is constant. Thus, in an embodiment of the tool guide 100 having two guide grooves 132, 134, the thickness of the top wall 116 adjacent the tool rail need not be uniform. However, in other embodiments as in Figures 27-30, the thickness of the top wall 116, i.e., the distance between the top support surface 129 and the bottom support surface 130, remains uniform.

Side entrance of dental drill

As in the embodiment shown in Figures 66 and 67, a wall has an inlet 125 for the dental drill. The inlet 125 and the tool guide 120 where tooth cutting occurs are coupled by a non-cut access channel 1202. The guide dental drill 200 is guided through the non-cut access channel 1202, enters through the inlet 125, and exits through the non-cut access channel 1202 through the same inlet 125 after cutting the teeth.

Cut at least three side surfaces with a single tool rail

Referring to Figures 66-74, in an embodiment, the dressing guide 100 has a single tool rail for cutting at least three side surfaces of a single tooth. Furthermore, the dressing guide 100 described above has an additional single tool guide configured to cut the four side surfaces of a single tooth. The first tool guide 120 is formed on the top wall 116 for placement on the second molar. The first tool guide 120 is configured to guide the dental drill to cut the subsequent surface of the second molar: the buccal surface, the entire cutting surface of the missing tooth, the portion of the cutting surface that is further away from the missing tooth, and the tongue surface. In some embodiments, the dental drill 200 enters via the inlet 125, moves through the non-cut access channel 125, and is embedded in the tool rail 120. The dental drill moves along the tool rail 120 and cuts the buccal surface, the entire cutting surface of the missing tooth, the portion of the cutting surface that is further away from the missing tooth, and the tongue surface. After all the cuts are completed, the dental drill moves back through the non-cut access channel 120. It leaves via entrance 125.

Still referring to Figures 66-74, in an embodiment, the dressing guide 100 has a tool rail arrangement to cut at least three sides of at least two teeth. The second tool guide 120 is formed on the top wall 116 for placement on the first and second front teeth. The second tool guide 120 is configured to guide the dental drill to cut the side surfaces of the first and second premolars. Although the buccal surface can also be cut to engage the ridge, if the cutting surface, the tongue surface, and a portion of the opposing cutting surface provide sufficient retention, the amount of cut of the buccal surface can be reduced for aesthetic reasons.

Vertical tool inlet hole

In the embodiment shown in Fig. 75A, the dressing guide 100 has a tool hole 124 that allows the protrusion structure 1102 to be inserted in the upper-lower direction. If the dental drill inlet is designed in the above manner, the side wall 110 need not have a gap, and thus the dressing guide 100 can be relatively stable, and the position of the dental drill can be well maintained during cutting.

In the embodiment as shown in Fig. 75B, the dressing guide 100 has a tool hole 124 on one side of the dressing guide. The non-cut access channel 1202 extends from each tool rail 120 to one end of the dressing guide and the tool hole 124 is formed at this end. When the dressing guide is installed, the tool hole 124 is located at one end of the dressing guide that is closer to the front end of the mouth, that is, the end of the incisor. Some patients cannot open their mouths broadly, but even for these patients, the front end of the mouth is more open than the part. The placement tool aperture 124 is proximate to the front end of the mouth, as in this embodiment, allowing the dental drill to be inserted into the front end of the mouth and then movable along the tool rail 120, thereby opening the mouth unnecessarily without the patient having to open the mouth.

Although each tool rail 120 of the embodiment shown in FIG. 75B has separate non-cut access channels and separate tool holes 124, in other embodiments, as shown in FIG. 75C, non-cutting of different tool rails 120 The engagement mode 1202 can gather and share a single tool entry aperture 124.

Another embodiment of a vertical tool inlet aperture

The embodiment of the invention as shown in Fig. 79 has a similar shape as the embodiment shown in Figs. 66-74 and is used to cut the second molar, the first premolar and the second premolar. The main difference between the dressing guides 100 of these embodiments is that the tool rail 120 shown in Fig. 79 has tool holes 124 at its ends. The above embodiment does not include a separate non-cut access channel 1202 or a non-cut guide portion that guides the drill to the starting point of the cut after being embedded in the tool hole 124. The above embodiment includes an example in which the non-cutting region is included in the tool hole 124 and the cutting starting point in the tool guide 120, but the distance (for example, the diameter of the cutting head of the dental drill) is short so that the region cannot be called a separation. The access channel 1202 or the non-cutting guide portion is cut. In the above embodiment, after inserting and entering the tool guide via the tool hole 124, the dental drill can start cutting the tooth almost immediately.

Referring to Figures 79A and 89, in one embodiment of the invention, the second molar tool rail 120 has two tool holes 124 that are accessed by the drill 200 at each end of the tool rail. The tool hole 124 is located in the side wall 110. In some embodiments, the dental drill 200 is embedded in a tool hole 124 and moves along the tool rail 120, cuts the side surface, and exits the tool rail 120 via different tool holes 124.

In the foregoing embodiment, the tool hole 124 on the buccal surface side serves as an inlet, and the tool hole 124 on the tongue surface side serves as an outlet. In other embodiments, the tool hole 124 on the side of the tongue surface can be used as an inlet, and the tool hole 124 on the side of the buccal surface can be used as an outlet. In other embodiments, a single tool hole 124 can be provided to the tool rail 120 and can be used as an inlet and an outlet.

Still referring to Fig. 79A, in an embodiment, a second tool guide 120 is formed on the top wall 115 for placement on the first and second premolars. The second tool guide 120 is formed to guide a portion of the side surfaces of the first and second front teeth. In an embodiment, the second tool rail 120 has tool holes 124 at both ends for access. These tool holes 124 are located in the side wall 110. The dental drill 200 is passed through the tool holes 124 One enters, then moves along the tool rail 120 and exits through a different tool aperture 126.

Mark the direction of the tooth drill and other information

In accordance with an embodiment of the present invention, the dressing guide 100 can include a symbol or indication to provide information to the dental operator. For example, referring to Fig. 89, the dressing guide of the embodiment has a symbol 136 indicating the direction in which the drill should move. Although not shown, in some embodiments, the symbol indicates whether the tool hole 124 is an inlet or may also be included as an outlet. In some embodiments, the aforementioned symbol 136 is placed where it can be easily seen by a dental operator. For example, in some embodiments, a symbol is provided on top. In some embodiments, the symbol can be raised or recessed and can have a color to highlight it in the background. In some embodiments, the symbol 136 indicating the direction of movement of the dental drill 200 can include different kinds of icons, such as the arrows shown in the figures. In an embodiment, the dental operator inserts the dental drill 200 into the tool hole 124 and rotates or moves the dental drill 200 in the direction of arrow 136 to cut the tooth.

In an embodiment, when the dentist gripping the hand coupled to the dental drill moves the dental drill along the tool rail, the dentist can push the hand from his/her body to move the dental drill. The dental drill can be moved by pushing the hand member through all portions of the tool rail or a particular portion of the tool rail. In another embodiment, the dentist can pull the hand piece from his/her body to move the dental drill. In a particular embodiment, the dentist can apply force to the hand from left to right to move the dental drill. In another embodiment, the dentist can apply force to the hand from right to left to move the dental drill.

Direction of rotation of the drill

In the embodiment as shown in Fig. 89, the dental drill 200 is rotated such that the tangential direction of the contact point between the cutting head 204 and the teeth is opposite to the direction of movement of the dental drill 200. In an embodiment, most of the particles of the cutting head are drawn toward the tangential direction 138. This is used to avoid particles blocking the dental drill 200. However, the present invention is not limited to the above, and in other embodiments, the tangential direction of the contact point between the dental drill 200 and the teeth and The direction of movement can be the same.

The structure of the tool hole of the dental drill

Referring to Figures 89 and 90, in the embodiment, the tool hole 124 is located at the end of the tool rail 120. The tool hole 124 has a top opening 140 and a bottom opening 142. In an embodiment, the size of the top opening 140 is sufficiently large that the cutting head 204 and the guiding protrusions 208, 210 of the dental drill 200 can pass therethrough. In an embodiment, the size of the bottom opening 142 is sufficiently large that the cutting head 204 of the dental drill 200 passes through but is not large enough to allow the lower guiding protrusion 210 to pass therethrough. In an embodiment, the stop 144 is located proximate to the bottom opening 142 to prevent the lower guide projection 210 from continuing to move downward.

In some embodiments, when the stopper 144 blocks the lower guiding protrusion 210, the upper guiding protrusion 208 is located at the height of the upper guiding groove 132, and the lower guiding protrusion 210 is located at the height of the upper guiding groove 134. . Therefore, when the dental drill 200 is stopped by the stopper 144 to continue to move downward, and when the guiding protrusions 208, 210 are embedded in the groove to move along the tool guide, the dental drill 200 can be rotated toward the tool guide 120 and mobile.

Referring to Fig. 91, in the embodiment, the top opening 140 and the bottom opening 142 of the tool hole 124 are sufficiently large to allow the dental drill 200, the cutting head 204, and the guiding protrusions 208, 210 to pass therethrough. The stop 146 is located below the tool hole 124 and is configured such that the end of the cutting head 204 is blocked. In some embodiments, the stop member 146 is located at a point where the guide projections 208, 210 and the guide groove are parallel, but the invention is not limited to the above.

Anti-tilt structure

As the dental drill 200 moves along the path provided by the tool rail 120 and cuts the teeth, the dental drill 200 can be tilted from the desired axis of its rotation 201. Tilting can occur in different directions. Either of the above directions includes a first tilt component along the direction of movement of the drill 200 of the tool rail 120 and a second tilt component perpendicular to the plane of the direction. These inclined components can be complemented by the use of the tool guide 120 and the dental drill 200 The shape and structure are substantially reduced. The factors that reduce the tilt may include the length of the drill neck 203, the diameter of the alert 203, the number of guide protrusions 208, 210, the shape of the guide protrusions 208, 210, the size of the guide protrusions 208, 210, and the guide protrusions. The positions of 208, 210, the length of the guiding surface 128 facing each other in the tool guide 120 corresponding to the above-mentioned topography, the width of the guiding surface 128, the number of guiding grooves, the shape of the guiding groove, and the guide The size of the groove and the position of the guide groove.

The implementation of the granules includes a sloping structure that avoids the end portion 210 of the cutting head 204 of the dental drill 200. As shown in Fig. 92, the dental drill 200 includes a cylindrical projection 212 that extends perpendicularly from the end of the cutting head 204. In this embodiment, the diameter of the cylindrical projection 212 is smaller than the diameter of the cutting head 204. Therefore, the ground 214 is formed between the cylindrical protrusion 212 and the cutting head 204. In this embodiment, no grinding or cutting edges are formed around the exterior of the cylindrical protrusion 212. Therefore, when in contact with the uncut surface of the tooth, the outside of the cylindrical protrusion 212 moves, and at the cutting time, the drill portion moves in the indicating direction 216, thereby avoiding tilting. During the above process, the teeth are guiding surfaces to guide the dental drill 200. In another embodiment, a grinding or cutting edge can be formed around the high ground 214.

Cutting edge line

As the dental drill 200 moves along the tool rail 120, the end cutting portion of the cutting head 204 cuts the teeth as it can, forming an edge line (cutting edge line) between the cut portion and the uncut portion. The helium is created such that it can reach and engage the cutting edge line. Referring to Fig. 24, an embodiment includes a dressing guide 100 and a configured dental drill 200 such that the end cut portion of the cutting head 204 moves along the gum line. In this example, the cutting edge lines on the teeth overlap or nearly overlap the gum line. In contrast, in the embodiment illustrated in Figure 92B, the end of the cutting head 204 is moved along a line between the side line 84 (or the cervical ridge) and the gum line. In the above example, the cutting edge line on the tooth can be easily seen because it is not on the gum line. In other embodiments, the dressing guide 100 and the dental drill 200 can be configured such that the end cutting portion of the cutting head 204 is along the tooth Some portions of the line 84 move above and along the other side of the side line 84. Further, although not shown, the trim guide 100 and the dental drill 200 can be configured such that the end cutting portion of the cutting head 204 moves below the gum line. In the above example, the cutting edge line of the tooth can be hidden beneath the portion of the gum.

Does not require any cutting part that is essentially undercut

If the cutting relies solely on the movement of the hand of the tooth operator, the undercut can be produced by cutting. However, in an embodiment of the invention, there is no significant undercut on the cut portion of the tooth when viewed along the inlaid axis of the complex. In other words, there is no undercut in the portion of the joint that is joined, as it is intended to be embedded in the axis. Referring to Figures 92A through 92E, the cut portion of the tooth is generally parallel to the embedded shaft 76 or inclined such that it tapers toward the occlusal surface as viewed along the tamping embedding shaft 76.

Angle of inclination of the cutting surface

In an embodiment of the invention, the angle a between the cutting surface of the teeth and the embedded shafts 76, 78 of the tamper 50 is in the range of from about 0[deg.] to about 3[deg.]. In embodiments, the angle a may be about 0.1°, about 0.2°, about 0.3°, about 0.4°, about 0.5°, about 0.6°, about 0.7°, about 0.8°, about 0.9°, about 1°, about 1.1, about 1.2, about 1.3, about 1.4, about 1.5, about 1.7, about 1.9, about 2, about 2.3, about 2.7, about 3, about 3.5, or about 4 . In other embodiments, the angle may be in the range of any of the above two angles. The above angles are much smaller than the angle typically formed by cutting without the need for a dressing guide, which is in the range of from about 6° to about 10°. Using a dressing guide to cut about 4°, about 5°, about 6°, about 7°, about 8°, about 9°, about 10°, about 11°, about 12°, about 13°, about 14° or An angle of about 15° is also possible. Here, the angle may also be in the range of any of the above two angles.

In an embodiment, the angle a between the cutting surface 80 and the (intended) embedded shaft 76 is constant or substantially the same at all of the cut portions. In other words, the angle α is the same or in a single tooth Either of any of the cutting surfaces is substantially identical. In this specification, substantially the same means that although the angle α is slightly different from position to position, the fraction of the intended angle is about ± 5%, about ± 6%, about ± 7%, about ± 8%, about ±9%, about ±10%, about ±11%, about ±12%, about ±13%, about ±14%, about ±15%, about ±16%, about ±17%, about ±18%, about ±19%, about ±20%, about ±21%, about ±22%, about ±23%, about ±24%, about ±25%, or in the range of either of the above numbers.

Tilting slope of the cutting head

In an embodiment, the cutting head 204 of the dental drill 200 is tilted from the end. The angle of inclination, or the angle β between the axis of rotation of the dental drill and the cutting surface of the tooth, is substantially the same as the angle a. In other embodiments, the slope angle a of the cutting surface 80 may not be constant over all of the cutting surfaces 80. And maintaining the inclination angle β of the dental drill along the outer surface of the dental drill to maintain a constant value. If the slope of the guiding surface 128 of the guiding slot of the tool guide 120 changes with the embedding axis, the slope angle of the cutting surface 80 can be Compared to β is a different angle.

Cutting depth/thickness of teeth

In various embodiments of the invention, the cutting surface can have a slope angle ranging from about 0[deg.] to about 3[deg.]. Therefore, the depth or thickness of the cut can be made smaller than the conventional method of cutting without using the dressing guide. The trim guide of the embodiment of the present invention allows the tamper to be engaged after cutting only the enamel layer of the teeth. When only the enamel layer is cut, the step of cutting a substantial portion of the tooth (such as a crown or cutting three or four surfaces of the tooth) can be performed without anesthesia. In another embodiment, it is possible to cut the ivory portion, although it is preferred to only cut the layer.

According to one embodiment of the invention, the depth (thickness) of the cut portion is that most of the teeth have been cut to be significantly smaller than cut by other methods. More specifically, when viewed along the intended axis of embedding, the depth of the cut near the cervical spine or line is about 0.1 mm, about 0.2 mm, about 0.3 mm, about 0.4 mm, about 0.5. Mm, approx. 0.6 mm, approx. 0.7 mm, approx. 0.8 mm, about 0.9 mm, about 1.0 mm, about 1.1 mm, about 1.2 mm, about 1.3 mm, about 1.4 mm, about 1.5 mm, about 1.6 mm, about 1.7 mm, about 1.8 mm, about 1.9 mm, about 2.0 mm , about 2.1 mm, about 2.2 mm, about 2.3 mm, about 2.4 mm, about 2.5 mm, about 2.6 mm, about 2.7 mm, about 2.8 mm, about 2.9 mm, or about 3.0 mm. Also. The depth of the cut near the cervical spine or line can also be within the range of both of the above figures. Preferably, the depth of the cut is about 0.5 mm, about 0.6 mm, about 0.7 mm, about 0.8 mm, about 0.9 mm, about 1.0 mm, about 1.1 mm, about 1.2 mm, about 1.3 mm, about 1.4 mm, about 1.5. Mm, about 1.6 mm, or within the range of both numbers.

Thickness of the fixed part

Since the depth of the cut is small, the thickness of the fixed portion 52 of the tamper 50 joined to the above position can also be substantially small. When a thin fixed portion of the material is allowed, the depth of the cut can also be small. The thickness of the tantalum bonded to the cutting surface 80 is measured as the depth of the cut tooth, i.e., measured from the same position from the cervical ridge or line. The thickness of the complex can be about 0.1 mm, about 0.2 mm, about 0.3 mm, about 0.4 mm, about 0.5 mm, about 0.6 mm, about 0.7 mm, about 0.8 mm, about 0.9 mm, about 1.0 mm, about 1.1 mm, About 1.2 mm, about 1.3 mm, about 1.4 mm, about 1.5 mm, about 1.6 mm, about 1.7 mm, about 1.8 mm, about 1.9 mm, about 2.0 mm, about 2.1 mm, about 2.2 mm, about 2.3 mm, about 2.4 Mm, about 2.5 mm, about 2.6 mm, about 2.7 mm, about 2.8 mm, about 2.9 mm, or about 3.0 mm, or in the range of both numbers. Preferably, the thickness of the complex is about 0.5 mm, about 0.6 mm, about 0.7 mm, about 0.8 mm, about 0.9 mm, about 1.0 mm, about 1.1 mm, about 1.2 mm, about 1.3 mm, about 1.4 mm, about 1.5 mm, approximately 1.6 mm, or in the range of both of the above numbers.

The inner side surface of the fixed portion

The three-dimensional shape and size of the inner side surface 59 of the fixed portion 52 of the tamper 50 precisely reinforces the three-dimensional shape and size of the cutting surface 80 formed on the arch teeth. Please refer to figure 92D, the above internal side Surface 59 is angled with reference to the intended incorporation of shaft 76. The above slope angle γ is substantially similar to the angle α. In other embodiments, the angle γ can also be slightly greater than a.

tolerance scope

Errors are unavoidable in the steps of manufacturing and cutting. However, the use of a dressing guide and a dental cutting tooth in accordance with an embodiment of the present invention results in substantially similar results for the intended cut surface image of the CAD/CAM system produced during the design phase of the dressing guide. The comparative data obtained from the three-dimensional data scan of the real cut teeth using the CAD/CAM system with data simulating the expected cut surface image shows that the average data from the true cut tooth error is about 20μ, about 40 μ, about 60 μ, about 80 μ, about 100 μ, about 120 μ, about 140 μ, about 160 μ, about 180 μ, about 200 μ, about 220 μ, about 240 μ, about 260 μ, about 280 μ, about 300 μ, or the above number Within the scope of both.

If the error occurs repeatedly under the same conditions (material of the dressing guide, manufacturing tool used for the dressing guide, material of the drill, etc.), the above error can be greatly reduced by subsequent correction measurement. Not only is the post-correction measurement performed, but the average error range is preferably about 100 μ, or more specifically about 20 μ, about 40 μ, about 60 μ, about 80 μ, or about 100 μ. Moreover, the average range of such errors may be within the range of either of the above numbers. When data is obtained from a real cutting tooth, the dental drill 200 does not need to apply force to tilt in the tool rail 120, and the cutting step must be performed to tilt in the tool rail 120, and the cutting must be performed to minimize any errors. Considering the fact that the range of the above-mentioned errors is more unpredictable by cutting the minimum number and the shape of the real cutting tooth obtained by not excessively changing its original shape.

The shape of the fixed part of the complex

In the embodiment of the present invention, the fixed portion 54 of the tamper 50 does not need to have an annular shape. As shown in Figures 71 and 72, the fixed portion 54 of the iliac crest is joined to the open molar. In the illustrated embodiment The fixing portion 54 is engaged with the tongue portion 542 including the engaging tongue surface and the cheek portion 544 that engages the buccal surface, wherein the two portions face each other. The tongue 542 and the cheek 544 include internal surfaces that face each other. Just as the fixed portion 54 engages the molars, the molars conform to the inner surfaces of the two facing each other, causing a retaining force to be fixed. In addition, the proximal portions 546, 548 that engage the two proximal surfaces of the molars also face each other to maintain the iliac crest in position.

On the other hand, as shown in Figs. 71 and 72, the fixed portion 55 of the second premolar does not include a portion to be joined to the buccal surface. However, in the above example, the side portions 556, 558 are disposed facing each other, and the inner surfaces of the side portions 556, 558 face each other. As described above, the second front molars conform to the inner surfaces facing each other, resulting in a retaining force to fix the ridge. The first front fixed tooth portion 56 has a similar design with its side portions 566, 568 facing each other. The inner surfaces of these side portions 566, 568 face each other. As described above, the first front molars are embedded between the inner surfaces facing each other, causing a holding force to fix the ridge. In the embodiment described herein, the retention of the combined first premolar and the retention of the second premolar provide sufficient retention.

Protection of the occlusal surface

The use of a dressing guide as shown in Figures 66-74 and a modified tooth procedure can be protected without cutting. In the illustrated embodiment, the number of cuts can be precisely controlled by the use of a trim guide. By using the dressing guide as shown in the embodiment, when only the minimum number of the test surfaces is cut, sufficient holding force between the tamper and the teeth can be maintained. This allows the teeth to substantially maintain their original shape and strength.

On the other hand, the traditional method of cutting a larger number of cuts results in less residual teeth, requiring a thicker crown to increase tensile strength and endure the increased strength of chewing. In order to accomplish this, cutting of the occlusal surface is required. In addition, if the number of cuts is large to cut into the ivory layer, the fangs can spread along the boundary between the gingival and the teeth even if the ridge is covered. In order to reduce the above risks, conventional oral procedures require cutting of the occlusal surface and covering all of the occlusal surfaces having a crown.

However, if minimizing abrasive trimming (or cutting) is performed as shown in the examples, cutting of the occlusal surface is not always required. In addition, since the cutting is performed only in the enamel layer if possible, it is less risky to spread to the dentin of the dentin through the boundary surface between the teeth and the gingival complex. Therefore, the occlusal surface is not cut by the above embodiment. However, other embodiments may include a cut portion of the occlusal surface to engage the ridge.

As shown in Figures 71-74, the haptic 50 includes an extended projection portion (inlaid portion) 552 that extends and protrudes from the proximal end portion of the top portion of the fixed portion 54. The extended projection portion 552 closely conforms to the non-functional groove at the cusp of the occlusal surface of the arch tooth 70 to increase the retention of the tamper. In the above examples, the non-functional grooves may be pre-existing and natural or artificially formed by using, for example, a dressing guide. When the groove is artificially formed, it may be referred to as a mosaic bridge.

Contact point protection

Prior to cutting, the arch teeth 70 and the proximal teeth 72 are in contact at a point of contact. In an embodiment of the invention, the arch teeth are not lost prior to cutting without damaging the contact points such that the function of the arch teeth is cut. In an embodiment, at least the contact points of all of the contact surfaces or contact surfaces between the arch teeth 70 and the proximal teeth 72 are not cut during the cutting process. As shown in the figures 71-74, although the fixed portion 54 of the first premolar is in contact with the portion of the tongue of the first premolar and the near midplane, the iliac crest does not cover the entire near midplane, thus maintaining the The contact point between a front molar and a canine.

Moreover, in the embodiment as illustrated in Figures 71-74, the fixed portion 54 of the haptic 50 on the second molar comprises a first wing extending from the artificial tooth 52 and covering the middle and buccal surfaces of the molar. The end extends to the transition zone between the distal or buccal surface and the distal midsection. The second wing on the other side extends from the artificial tooth 52 and covers the middle of the second molar and the tongue surface. The end extends to the distal mid-surface or the transition zone between the tongue and the distal mid-surface. Therefore, the fixed portion 54 can be protected from being located in the second The point of contact between the tooth and the wisdom tooth (not shown). In the method of cutting and topography according to an embodiment of the present invention, the protection of the above contact points is possible because sufficient holding force can be provided without covering all of the side surfaces.

Trimming guide manufacturing and materials

In an embodiment of the invention, the dental drill 200 is rotated at high speed (for example, 3,000-400,000 rpm) when the teeth are cut. Since the dressing guide 100 is in contact with the neck 203 of the dental drill 200 that rotates at a high speed, it should be made of a material that is not easily damaged by physical contact and that is not converted by frictional heat. This material should also be biocompatible. For example, a plastic resin, ceramic, or metal material can be used. More specifically, for example, gold, gold alloy, titanium, titanium alloy, glass, and a polymer compound can be used. If the material of the dressing guide is transparent or translucent, the mounting state or cutting process can be easily observed.

The trim guiding device 100 can also be manufactured by using a manufacturing process via a CNC machining center or by using an additive manufacturing process via three-dimensional printing or stereolithography. The manufacturing method of manufacturing the dressing guiding device 100 of the present invention is not limited to the above method. Although the dressing guide 100 in the above embodiment is made of a single material, the dressing guide 100 can be made of at least two materials. For example, portions of the dressing guide 100 surrounding the tool rail 120 can be fabricated from the materials described above, and the remainder can be fabricated from other materials.

Embodiments as shown in Figures 3, 4, 6-9 and 24

Referring to Figures 3, 4, 6-9 and 24, the dressing guide 100 in accordance with an embodiment of the present invention includes a tool guide 120 in a second guide portion 104 that allows cutting of two teeth. The two guiding portions 104 are joined to form a single piece. While the guide portion 104 is directly joined to the arch tooth 70 as in the illustrated embodiment, another embodiment may include a structure with an additional mounting portion 102 that engages the proximal tooth 72 adjacent the arch tooth.

The tool rail 120 has a circular curve shape to allow all side surfaces to be processed at one time. The top wall 116 of the guide portion 104 includes a central portion 1162 and a peripheral portion 1164 that is divided by the tool rail 120. The central portion 1162 and the surrounding portion 1164 are connected by a suitable number of rod connectors 1166 to avoid separation of the central portion 1162. In the illustrated embodiment, the wall 110 extends below the line.

In the illustrated embodiment, the non-cut access channel 1202 of the annular tool rail 120 extends from the sidewall 110. The end of the non-cut access channel 1202 is a tool inlet 125 that is located outside of the sidewall 110. The dental drill 200 enters through the inlet 125 and passes through the non-cut access channel 1202 to reach the tool rail 120. The dental drill 200 moves along the tool rail 120 to cut the side surface of the tooth. The dental drill 200 can also cut the connector 1166 as the side surface is cut to move further along the tool rail 120. Figure 24 shows an embodiment in which the side surface is cut using the dressing rail 100. As shown in Figures 14, 19, 20 and 44, the tool inlet 125 can be located on the side wall 110 of the non-cutting access channel 1202.

Example shown in Figure 5

The dressing guide 100 according to the embodiment, as shown in FIG. 5, includes two connectors 1166. As a result, the tool guide 120 includes two portions that are separated by the connector 1166. Each portion has its own non-cut access channel 1202 in the tool rail 120. In addition, each non-cut access channel 1202 has its own inlet 125. The dressing guide 100 of the above configuration allows cutting of all side surfaces of the teeth without cutting the connector 1166. The size, configuration, location, and number of connectors 1166 can vary depending on the shape of the teeth and the drill.

Connector

The example in Figures 3-9 includes a rod connector 1166. When the connector 1166 extends across the guide slot, it is possible that the diameter of the cutting head 204 of the dental drill 200 is sufficiently large to cut the surface of the tooth under the connector 1166 without damaging the connector 1166. In other words, if the cutting portion is located below the connector 1166, if the diameter of the cutting head of the dental drill 200 is larger than the width of the connector 1166, The cutting head 204 of the dental drill can reach the surface of the tooth located below the connector 1166. Therefore, the connector 1166 does not interfere with the cutting process. In the above embodiment, the number of tool inlets 125 is equal to the number of portions of the tool rails 120 formed by the connectors 1166 described above.

The width of the connector 1166 can vary depending on the material of the dressing guide 100. If the material of the dressing guide 100 is tough, the width of the connector 1166 can be narrower than the dressing guide 100 made of a relatively weak material. This tool guide 120 does not have a toroidal curve shape, for example, it is linear or sliced, and the disconnector 1166 is not required.

Embodiments shown in Figures 10 and 11

The dressing guide 100 as shown in Figures 10 and 11 includes sidewalls 110 that do not extend below the line or only slightly extend. In the above embodiment, whether or not the dressing guide 100 is properly engaged with the arch teeth 70 can be easily confirmed by observing the boundary of the line or by using a probe. Thus, it is not necessary to have a separate interruption 118 that opens a portion of the sidewall 110 to confirm that the dressing guide 100 has been properly engaged. In this embodiment, the cutting step can also be seen under the trim guide 100.

Cooling water flow

In an embodiment, the cooling water may flow from the hand member 230 via the guide slot and tool hole 124 of the tool rail 120, for example, via the interior of the guide portion 104 to exit via the interruption portion 118 located below the line. (See Figures 94B, 95B, 99B and 100B). In other embodiments, the cooling water may flow through additional holes or some other opening. The size of the opening may vary depending on the amount of cooling water and the rigidity of the dressing guide 100.

Embodiments shown in Figures 12 and 13

The entrance of the dental drill 200 is located inside the side wall 110, i.e., as the aperture 124 of the top wall 116. Since the recess is not formed on the side wall 110 according to the above-described topography, the conversion of the dressing guide 100 is unlikely of.

Embodiments shown in Figures 14-17

According to the embodiment as shown in Fig. 14, the dressing guide 100 includes the entrance of the dental drill 200 on the side wall 110 and the tool guide 120 is formed only along a portion of the side surface of the tooth. The dressing guide 100 of the embodiment as shown in Fig. 15 includes a tool rail 120 formed along the side wall 110 to allow cutting of the nip surface. The dressing guide 100 of the embodiment as shown in Fig. 16 includes a tool rail 120 formed on the side wall 110 to permit installation of a band-shaped recess on the surface of the cheek or tongue. The dressing guide 100 of the embodiment shown in Fig. 17 includes a guide hole on the top wall 116 to form the rest on the occlusal surface.

Example as shown in Fig. 18.

The dressing guide 100 of the embodiment as shown in Fig. 18 includes a tool guide 120 that allows continuous cutting of the tongue or cheek surface of a plurality of teeth at a time. After the above-described cutting, 50 pieces of the entangled monomer are placed on the three teeth, and an unstable tooth (for example, an intermediate tooth) can be fixed in position.

An embodiment as shown in Figures 19-21

The dressing guide 100 according to the embodiment as shown in Figures 19-21 includes a tool guide 120 that allows cutting of the side surfaces of the plurality of anterior teeth. The dressing guide 100 as shown in Fig. 19 includes a tool hole located on the side wall 110. The dressing guide 100 as shown in Fig. 21 includes a tool hole located on the top wall 116.

Embodiments as shown in FIGS. 22 and 23

The dressing guide 100 according to the embodiment as shown in Figures 22 and 23 includes a tool rail 120 formed on the side wall 110 of the tongue surface to allow cutting of the tongue surface of the multiple anterior teeth. In the embodiment as shown in Fig. 23, the dressing guide 100 includes two tool guides 120 on each of the front teeth to form a position. Two cavities on each anterior teeth. As such, at least two tool rails 120 can be joined to a single tooth as desired. The dressing guide 100 of the embodiment shown in Fig. 23 includes a tool guide 120 on each of the front teeth to allow cutting along the lingual surface of each anterior teeth.

Embodiment as shown in Fig. 24.

Referring to Figure 24, the dressing guide 100 of the embodiment includes a tool guide 120 having a vertical curve. In the example where the bottommost portion of the tooth to be cut is cut vertically along the gum, the tool guide 120 may also include a curve in which the vertical curve is substantially flat to the portion to be cut. As shown in Figures 25 and 26, the tool rail 120 is configured to allow for a line that is parallel to the channel or trajectory of the bottommost point of the dental drill 200. In another embodiment as shown in Fig. 25, the tool guide 120 is configured without any vertical wave curve because there is no vertical wave curve along the bottommost path of the dental drill. On the other hand, when the vertical wave curve exists along the bottommost path of the dental drill, as shown in Fig. 26, the tool guide 120 is mounted with a vertical wave curve substantially parallel to the vertical wave curve of the bottommost path of the dental drill. Thus, in the illustrated embodiment, the tool guide 120 is configured in accordance with the shape of the bottommost passage of the dental drill.

In the embodiment as illustrated in Figures 24, 25 and 26, the guide projections 207 of the dental drill 200 move along the top support surface 129 of the tool rail 120. Thus, if the vertical curve is present in the bottommost channel of the dental drill, the top support surface 129 also includes a substantially parallel vertical curve. In the embodiment in which the guiding protrusions 208, 210 are moved along the guiding grooves 132, 134, as in the embodiment shown in Figures 38 and 39, if the vertical curve exists in the bottommost path of the dental drill, the guiding groove 132, 134 also contain vertical curves that are as large as parallel.

On the other hand, in the embodiment as shown in Fig. 24, the tool guide 120 is configured such that the bottom end of the dental drill 200 follows the gum line. In another embodiment, the tool rail 120 can be placed at a vertical maximum point or the long side of the cutting head 204 can be shorter to allow the bottom end of the dental drill 200 to move along the path between the line and the gum line (see Figure 108). Therefore, once the portion to be cut is determined, the passage at the end of the cutting head 204 is determined, and the vertical curve of the tool guide 120 is based on the vertical curve of the passage. was decided.

As shown in Fig. 24, when the dental drill 200 cuts the tooth 70 along the tool guide 120, the dental drill 200 is along the top support surface of the tool guide 120 to guide the protrusion (or guide groove, see 31, 32, 33, 38, and 39) Follow the vertical curve to move up and down and cut the teeth. The cut portion of the formed tooth is thus included in the bending step 82 of its bottommost portion, and the shape of the tamper 50 is configured to reinforce the above-described bending step. In other embodiments, the step at the bottommost portion may not be formed. Particularly in the case where the bottom end of the cutting head 204 is placed between the line and the gum line, an edge that is clear depending on the angle and depth of the cut may be invisible.

Different embodiments of dental drill and tool guide

Tilting can occur when the dental drill 200 cuts teeth along the tool rail 120. If excessive tilting occurs, it may cause cutting of unintended areas. Also, the amount of cut can be more or less than desired. When the above-mentioned error in cutting occurs, the combination of the complex 50 and the teeth may be incorrect or may cause subsequent difficulties. Embodiments of the present invention provide topography to minimize the above tilt.

In the embodiment as illustrated in Figures 24A and 27B, the dental drill 200 includes two disc shaped guide projections 208, 210, one of which is positioned over the other. The top guide protrusion 208 of the dental drill 200 is supported and moved by and along the top support surface 129 of the tool rail 120, while the bottom guide protrusion 210 is supported and moved by and along the bottom support surface 130, allowing the dental drill 200 moves. Figures 9 and 43 show the cutting procedure using the dental drill 200 described above.

In the embodiment as illustrated in Figures 28A and 29B, the dental drill 200 includes two spherical guide projections 208, 210, one of which is positioned above the other. As described in Fig. 40, the spherical projections are preferred for movement along the tool guide 120 having a vertical curve. Since the contact area is small when the dental drill 200 is rotated and moved to cut the teeth, the inclination and friction of the dental drill 200 can be lowered. As shown in Fig. 41, the dental drill 200 having the disc-shaped guide protrusions 207 having a relatively small diameter can be smoothly or even slightly vertical. Move with the curve. However, as shown in Fig. 42, the dental drill 200 having the disc-shaped guide projections 207 having a larger diameter may also incorrectly follow the tool guide 120 having a vertical curve. Although the above-described guide protrusions 207 having a large diameter can facilitate the avoidance of tilt when moving, the movement along the vertical curved portion can be restricted by the large friction of the surface having the tool guide 120.

In the embodiment as shown in Figures 29A and 29B, the dental drill 200 is moved along a tool rail 120 that includes a guiding surface 128 on only one side. In addition, the dental drill 200 moves along the tool rail 120 via the contact between the leading protrusions 208, 210 and the top and bottom corners of the guiding surface 128. If the topography of the tool guide of the above embodiment is used, the center portion 1162 and the connector 1166 as shown in Fig. 3 are not required. In the embodiment as illustrated in Figures 30A and 30B, the neck 203 of the dental drill 200 has a small diameter and conforms to and moves along the tool rail 120.

On the other hand, in the embodiment as shown in Figs. 31A and 31B, the dental drill 200 includes a single spherical guiding protrusion 207. The guiding projections 207 conform to the hemispherical grooves of the guiding surface in the tool guide to guide the dental drill 200. In the embodiment as illustrated in Figures 32A and 32B, the dental drill 200 includes an elliptical guiding protrusion 207. As the dental drill 200 moves along the tool rail 120, the elliptical guiding protrusions 207 move along the tool rail 120.

In the embodiment as illustrated in Figures 33A and 33B, the dental drill 200 includes two spherical guide projections 208, 210. In both, the bottom guide projection 210 conforms to the recess 131 that provides the guide surface 128 of the tool rail 120. When contacting the top support surface 129 of the tool rail 120, the top guide projection 208 moves.

In the embodiment as illustrated in Figures 34A and 34B, the dental drill 200 includes two spherical guide projections 208, 210. As the dental drill 200 moves along the tool rail 120, when contacting the bottom support surface 130 of the tool rail 120, the bottom guide protrusion 210 moves and the top guide protrusion moves when it contacts the top support surface 129.

In the embodiment as illustrated in Figures 35A and 35B, the dental drill 200 includes a shaped guide projection 207 at the top. Further, the top of the cutting head 204 includes a hemispherical shape to function as a guiding protrusion. As the dental drill 200 moves along the tool rail 120, the guide projection 207 moves when contacting the top support surface 129 of the tool rail 120, and the top of the cutting head 204 moves as it contacts the bottom support surface 130 of the tool rail 120.

In the embodiment as illustrated in Figures 36A and 36B, the dental drill 200 includes a spherical guide projection. The top support surface 129 of the tool rail 120 includes a recess. As the dental drill 200 moves along the tool rail 120, portions of the spherical guide projections conform to and move along the grooves formed on the top support surface 129 of the tool rail 120. In another embodiment as shown in FIG. 36C, the dental drill 200 includes two spherical guide projections 208, 210. Each of the top support surface 129 and the bottom support surface 130 of the tool rail 120 includes a recess. Each of the guiding protrusions 208, 210 conforms to and moves along each of the opposing grooves. On the other hand, in the embodiment as shown in Figs. 37A and 37B, the guide projection 207 moves as the dental drill 200 moves along the tool rail 120 and contacts the top support surface 129 of the tool rail 120.

In the embodiment as illustrated in Figures 38A and 38B, the dental drill 200 includes two spherical guide projections 208, 210 of different sizes. The side guide surface 128 of the tool rail 120 includes grooves 132, 134 that reinforce each of the guide protrusions 208, 210. As the dental drill 200 moves along the tool rail, the two guide projections 208, 210 move in time and along each of the grooves 132, 134. In the embodiment as illustrated in Figures 39A and 39B, the dental drill 200 includes two spherical guide projections 208, 210 of the same size, and as the dental drill 200 moves along the tool guide 120, the two guide projections 208, 210 conforms to and moves along each of the grooves 132, 134.

In the embodiment as described in pages 88A and 88B, the dental drill 200 includes two spherical guide projections 208, 210, one of which is positioned above the other. The guide surface 128 on one side of the tool rail 120 includes rectangular recesses 132, 134. The guide protrusions conform to and move along the aforementioned grooves 132, 134. In the above embodiment, the contact area between the grooves 132, 134 and the guiding protrusions 208, 210 may be smaller than the first The embodiments described in Figures 38 and 39. Therefore, the friction can be lowered, allowing the tooth bay to rotate and smoothly move. In addition to being a rectangle, the shape of the groove can also be other polygons, such as a triangle, a trapezoid or a pentagon.

Cooling fluid flow

A cooling fluid, such as water, is generally provided to cool the dental drill 200 and teeth during cutting. The flow of the cooling fluid described above serves to not only cool the teeth and the dental drill 200, but also to remove the fragments of the teeth and the particles from the dental drill.

In the embodiment as shown in Fig. 43, the dressing guide 100 includes a hole 170 to allow the above-described cooling fluid to flow therethrough. In an embodiment, the aperture 170 is located below the line. In other embodiments, as shown in Figures 11, 13, and 89, the sidewall 10 may extend only to the line or include an interruption 118 to allow the cooling fluid to flow therethrough.

Single dressing guide for cutting the bite and side surfaces

In the case where the occlusal and side surfaces of the arch are to be cut, for example, crown or crown and bridge, the single dressing guide may include a tool guide that allows for cutting of the bite and side surfaces. In the above example, when the cutting occlusal surface is cut as measured, the dressing guide can be moved relative to the teeth. Then, due to the movement of the dressing guide, precise cutting may not be performed on the occlusal surface. This is a special example in which the dressing guide is placed directly on the arch teeth or the arch teeth are not sufficiently supported by adjacent teeth. Further, when the side surface is cut, the tool rail of the nip surface may be damaged. Even if the rear side surface is cut at the cutting nip surface, the tool guide that must cut the side surface may have been damaged.

Embodiments of the present invention address the above problems via strategic positioning of the navigation slots. The tool guide 120 as shown in Fig. 4-54 illustrates the above embodiment. For example, the tool rail 120 that cuts the side surface can be located within the tool rail 120 used to cut the occlusal surface, or in other words, when the self-biting surface When viewed from above, it is closer to the teeth. Next, the tool guides 120 that guide the dental drill 200 to cut the occlusal and side surfaces do not span each other. In the above embodiment, the surface is first cut, followed by the occlusal surface.

In contrast, the tool rail 120 that cuts the side surface can be located above the tool rail 120 that extends from the tongue and cheek directions of the cutting occlusal surface, or in other words, from the teeth when viewed from the side of the side surface. Next, the dental drill 200 is guided to traverse the tool rails 120 of the occlusal and side surfaces. In the above embodiment, the occlusal surface is first cut, followed by the side surface.

The order in which the different surfaces are cut may vary depending on the bite or side surface that strongly supports the trim guide. For example, if the side surface provides stronger support, it is advantageous to cut the occlusal surface first and then the side surface. However, if the occlusal surface provides strong support, it is advantageous to cut the surface first and the thickness is the occlusal surface.

In other embodiments of the present invention, as shown in Figures 80-85, two trimming guides 1002, 1004 are used when cutting the crown of the tooth. The above embodiments are discussed in more detail below.

Example as shown in Figures 44-54

According to the embodiment as shown in Figures 44-54B, the bite and side surfaces of the arch teeth 70 can be effectively cut by using a single dressing guide 100. In the illustrated embodiment, the tool guiding device 120 that cuts the side surface and the tool guiding device 120 that cuts the occlusal surface are configured to not collide with each other when cutting the teeth 2. This topography avoids damage to the tool rail 120 when cutting.

Figures 44-55B show a dressing guide 100 for cutting teeth to mount a crown and bridge. The dressing guide 100 has a tool guide 120 for guiding the dental drill 200 to cut the occlusal surface and guide the tool guide 120 of the dental drill 200 to cut the side surface. Tool rail 120, as explained above, includes a guide slot between two guiding surfaces 128 that face each other. The neck 203 of the dental drill 200 conforms to the guide slot of the tool rail 120, allowing the dental drill 200 to move along the tool rail 120.

The dressing guide 100 described above can be mounted to the patient's mouth and allows for the cutting of the occlusal and side surfaces prior to removal.

In the illustrated embodiment, the side surface tool rails 120 have dental drill inlets that cut across the sidewalls of adjacent teeth 72 proximate the arch teeth 70. The tool guide 120 of the occlusal surface has two different tool guides for each of the arch teeth 70. More specifically, prior to each arched tooth 70, the separating tool guides the portion that cuts closer to the occlusal surface of the cheek and the portion that is used to cut the occlusal surface closer to the tongue. Each bite tool guide 210 has a dental drill inlet 125 located at a top wall 116 of the dressing guide 100.

Cutting the occlusal surface before cutting the side surface

In the example of cutting the occlusal surface before the side surface, the dressing guide 100 is configured such that the tool guide 120 for cutting the side surface is not damaged when the occlusal surface is cut by the dental drill 200. Due to the above structure, the dental drill 200 is completely maintained to be supported while cutting the side surface after cutting the occlusal surface. More specifically, as shown in FIGS. 48B, 50B, and 51B, the tool guide 120 for cutting the side surface may be located farther than the intended passage of the cutting head 204 of the dental drill 200 for cutting the occlusal surface. In other words, in the 48B, 50B, and 51B drawings, the tool guide 120 for cutting the side surface is located higher and farther from the teeth. The above-described structure avoids the side surface of the tool guide 120 being damaged when the dental drill 200 cuts the occlusal surface. In the example where the connector 1166 is located in a guide slot and rail that spans the side surfaces, the connector 1166 can be mounted in position such that it is not cut during cutting of the occlusal surface (see Figure 48B).

The dressing guide 100 for cutting the occlusal surface prior to cutting the surface may also deliberately design the tool rail 120 that damages the occlusal surface when cutting the side surface. This is because the cutting of the occlusal surface has been completed by time and the side surface has been cut and the tool guide 120 of the occlusal surface is no longer needed. The above-described design of the dressing guide 100 that allows for a narrower portion allows the dressing guide 100 to conform to the necessary size limits. When the dressing guide 100 of the above structure is used, the user (tooth operator) The occlusal surface must be instructed prior to cutting the side surface.

Cutting the side surface before occluding the surface

In the example of cutting the side surface before the occlusal surface, the dressing guide 120 is configured such that the tool guide 120 for cutting the occlusal surface is not damaged by the dental drill 200 when cutting the side surface. Due to the above structure, the dental drill 200 is maintained to be fully supported when the occlusal surface is cut after cutting the side surface. More specifically, the tool guide 120 of the occlusal surface can be located farther from the intended passage of the cutting head 204 of the dental drill 200 from the tooth than the cutting surface 200. The above structure prevents the tool guide 120 of the nip surface from being damaged by the dental drill 200 when cutting the side surface.

The dressing guide 100 for cutting the side surface prior to the occluding surface may also deliberately design the tool rail 120 that damages the side surface when the occlusal surface is cut. This is because the cutting of the side surface has been completed by time and the occlusal surface has been cut and the tool rails 120 of the side surfaces are no longer needed. The above-described design of the dressing guide 100 that allows for a narrower portion allows the dressing guide 100 to conform to a particular limited size. When the dressing guide 100 of the above design is used, the user (tooth operator) must be instructed to cut the side surface before cutting the occlusal surface.

Confirm the installation status of the dressing guide

As shown in Figures 49 and 54, the dressing guide in which the patient has been properly engaged can be confirmed. The mounting state of the dressing guide can be confirmed by the observer, as shown in Fig. 49, or via the use of the probe 250, as shown in Fig. 54.

Example as shown in Fig. 56

According to the embodiment as shown in Fig. 56, the dental drill inlet of the tool guide for accessing the cutting side surface is located on the top wall in the form of a hole. As described above, the above-described inlet structure does not have an opening in the side wall, allowing the dressing guide 100 to be stably held on the teeth.

Example as shown in Figures 57-65

In an embodiment, as shown in Figures 63-65, the tampon 50 comprising the fixed portion 54 is joined to the arch teeth 70 on either side of the missing tooth and the artificial tooth 52 is positioned between the two fixed portions 54. As shown in Fig. 65, each of the two fixing portions 54 includes a fixing protrusion 58 which is insertable and fixed to a circular arc or horseshoe shaped fixing groove 86 formed in each of the front arch teeth 70 along the ring table. . In an embodiment of the invention, the fixed portion 54 is made of a metallic material such as gold, gold alloy, titanium, or titanium alloy, and the artificial tooth 52 is made of a suitable material for artificial teeth, such as gold or zirconia. . In other embodiments, the securing protrusions can be made of a ceramic material, such as zirconia, and a non-metallic material.

In an embodiment, the fixing protrusion is formed on the ridge and the groove is formed on the tooth to fix the ridge. In order to obtain sufficient holding force when fixing the fixing projections and grooves, the grooves must be accurately trimmed. More specifically, the three-dimensional shape and size of the fixing projections 58 formed on the fixed portion 54 of the tamper 50 must accurately reinforce the three-dimensional shape and size of the ridge fixing groove 86 formed on the teeth of the arch. When viewed along the desired axis of embedding of the tamper 50, all of the cutting surfaces forming the sidewalls of the tamping recess 86 must conform to or substantially conform to the desired axis of embedding. Likewise, all of the cutting surfaces forming the sidewalls of the retaining projections 56 must conform to or substantially conform to the desired axis of embedding when viewed from the desired axis of insertion of the tamper 50. Moreover, when the fixing protrusion 56 is embedded in and fixed to the 固定 complex fixing groove 86 by the embedded yoke, the gap between the side wall of the fixing protrusion and the side wall of the tamping fixing groove is, on average, less than about 60 μ. 80 μ, about 100 μ, 120 μ, about 140 μ, about 160 μ, about 180 μ, or about 200 μ. The above conditions are difficult to achieve without using the dressing guide and relying solely on the hand movement of the tooth operator.

As illustrated in Figures 57-62, the dressing guide 100 of the embodiment allows the front tongue surface to be cut along the annulus so that the iliac crest can be secured to the anterior teeth. The dressing guide 100 includes a tool rail 120 having an arc to guide the drill. In an embodiment, the ridges of the anterior teeth on the tongue surface 70 are fixed by the groove 86. Formed by the joint dressing guide 100 and along the ring as the dental drill moves along the tool rail 120.

Thus, the inner wall of the formed fixing groove 86 is not weakened compared to the axis required for the insertion. As shown in Fig. 23E, in the embodiment, the side surface 80 of the above-described tamping fixing groove 86 has a slope surface 80 which is compliant or slightly inclined with respect to the 赝 complex axis of the embedded portion 76. The angle formed between the inclined inner wall 80 and the line parallel to the complex axis of the entanglement, α, is in the range of from about 0° to about 3°. In embodiments of the invention, the angle may also be about 0.3, about 0.4, about 0.5, about 0.6, about 0.7, about 0.8, about 0.9, about 1 , about 1.1, about 1.2. °, about 1.3, about 1.4, about 1.5, about 1.7, about 1.9, about 2, about 2.3, about 2.7, about 3, about 3.5, or about 4 . In other embodiments, the angle may also be within the range of both of the above numbers. The grooves formed on the two teeth have the same axis embedded therein.

As shown in Figs. 23F and 65, the tamper-evident fixing projections 58 are formed such that they can be embedded and fixed in the yoke fixing recess 86. Therefore, the projections 58 on the two sides of the artificial teeth protrude in the same direction as the embedded shaft of the complex. In an embodiment, the side surface of the protrusion 58 may also have a slope angle that is the same or larger than the side surface of the ridge fixing groove 86. In the embodiment, the top surface and the structure of the above-mentioned fixing protrusion, the damper fixing groove, and the embedded yoke multi-axis are the same as those described in the embodiment shown in Fig. 23B.

Each of the tool guides 120 of the dressing guide 100 includes a raised structure 1102 that extends from the tongue side wall 110 and projects. The raised structure 1102 is included in a non-cut access channel 1202 in the tool rail 120 that extends to a tool entry aperture 125 located on the lingual side of the raised structure 1102. Thus, unlike the embodiment in which the inlet is located in the side wall 110, the notch is not formed on the side wall 110 of the conditioning guide 100 of the embodiment, allowing the dressing guide 100 to be securely engaged. The above-mentioned tool inlet having a protruding structure extending from the side wall can also be applied to the dressing guide of the posterior teeth as the anterior teeth.

Example as shown in Figures 76-78

As shown in Figures 76-78, the dressing guide 100 in accordance with an embodiment includes a tool guide 120 that guides a dental drill along the annulus to cut the two front teeth. The trim guide is different from the embodiment shown in Figures 57-65 in which the tool holes 124 are configured to allow the drill 200 to be inserted up and down and to provide an opening portion 118 at the bottom of the sidewall 110. Other basic structures of the embodiments are similar to other embodiments, as shown in Figures 57-65.

Dressing guide for cutting teeth

One or two dressing guides can be used to cut the crown bridge to cut the teeth. In an embodiment where the two dressing guides are used to cut a single tooth, one of the dressing guides is configured to engage a tooth prior to completion of any of the cuts. Other trim guides are configured to engage a tooth after cutting portions to allow for cutting of the uncut portion after the first cutting step. Thus, the first conditioning guide is used to cut a portion or all of the proximal, occlusal, buccal or lingual surfaces of the teeth. Next, the second dressing guide is used to cut the remainder of the additional cut that is required after the cutting step using the first dressing guide.

The use of the second dressing guide facilitates maintaining the position of the dressing guide when cutting the teeth. This is also true because the teeth maintain the uncut portion to provide retention to maintain the first dressing guide in place of the dressing guide. The second conditioning guide can continue to maintain retention in portions that are not cut and will not be cut in all steps. Furthermore, the tool guides for the dressing guides for cutting the side surfaces and the tool guides for cutting the occlusal surfaces that span each other, thus making it less likely that the dressing guides become relatively large or complex. Therefore, it is possible to cut the teeth without having any conflict between the cutting side surfaces (specific cheeks, tongue and proximal surfaces) and the guiding slots for cutting the occlusal surfaces. In an embodiment, the dressing guide having a tool guide that is primarily used to cut the tongue surface of the tooth includes a occlusal surface for cutting the cheek side of the tooth (see Figure 82). In addition, another dressing guide having a tongue-surface tool rail for primarily cutting the teeth includes a tool guide for cutting the occlusal surface on the tongue side of the tooth ( See figure 84).

An embodiment as shown in Figures 80-85

Figures 80-85 show the attachment of the crown and bridge ridge 50 to the trimming guide to cut the trimmed teeth in accordance with one of the embodiments of the present invention. The first dressing guide 100, as described in FIGS. 80A, 81 and 82, is configured to cut the occlusal surface on the buccal side and the side surface on the lingual side and the occlusal surface on the lingual side under the cutting condition and Located on the side surface of the buccal side. The second trim guide 100, as shown in Fig. 80B, is configured to cut the remaining portion after cutting using the first dressing guide 100. These remaining portions are the gingival occlusal surface on the lingual side, the lateral surface on the buccal side, the gingival occlusion surface on the buccal side, and the lateral surface on the lingual side. Referring to Figures 81B and 81C, the first trim guide 100 is first engaged to cut the arch teeth and then removed. Next, as shown in FIGS. 83B and 83C, the second dressing guide 100 is engaged to cut the arch teeth 70. Once the second trim guide is removed, the cutting step is completed, as shown in Fig. 85. The crown and bridge complex 50 are then joined.

Example as shown in Figures 93-104

According to one of the embodiments, the dressing guide, as shown in Figures 93-104, is configured to cut the trimmed teeth to engage the crown. The first dressing guide 1002 of the pair, as shown in Fig. 93, is used to cut the cheek surface and the occlusal surface behind the lingual side. The mounting support portion 102 of the first trim guide 1002 includes a mouthpiece shaped shape to occupy only a small amount of space in the mouth.

To provide a tool rail 120 for cutting the buccal surface, the protrusion structure 150 extends from the top of the mounting support portion 102. The interior of the protrusion structure 150 includes a tool rail 120, and the tool rail 120 includes a tool hole 124. The protruding wall 152 surrounds the tool rail 120 and the tool hole 124. Further, in order to provide the tool guide 120 for cutting the occlusal surface on the lingual side, the protruding structure 160 extends from the side of the mounting fixing portion 102. The inside of the protrusion structure 160 includes a tool guide 120 Tool rail 120 includes tool holes 124. The protruding wall 162 surrounds the tool rail 120 and the tool hole 124.

At the same time, the second dressing guide 1004 for cutting the tongue surface and the occlusal surface of the tooth behind the cheek side wall comprises a mouthpiece shape. Similar to the first conditioning guide 1002, the second conditioning guide 1004 includes a first protruding structure 150 extending from the top to provide a cutting tongue surface for the tool guide 120 and extending from the side to provide for subsequent cutting on the buccal side The second protruding structure 160 of the tool guide 120 of the occlusal surface. The interior of these raised structures 150, 160 includes tool rails 120 and tool holes 124. The structure of the tool rail 120 and the tool holes 124 of the dressing guides 1002, 1004 can comprise any of the structures listed above or in the embodiments described below.

Example as shown in Figures 86-87

Referring to Fig. 86, the dressing guide 100 according to an embodiment of the present invention is used to cut the lip surface of the front tooth to be trimmed to join an aesthetically pleasing 50, such as a laminate. The dental drill, as shown in Fig. 87, can be used in combination with the trimming guide described in Fig. 86 to cut the trimmed teeth and join the laminated layer 50.

Repair of alveolar bone or other dental procedures using a dressing guide

The above-described embodiments have mainly used the dressing guide of the dental procedure to repair the missing parts of the teeth, such as a combination of bridges. The present invention, however, is not limited to the above use. In an embodiment of the invention, the dressing guide can be used not only to cut teeth but also to add material to support the alveolar bone when the alveolar bone is damaged or broken. In an embodiment, after cutting the alveolar bone, the material used to support the alveolar bone can be embedded to stabilize the fractured portion or repair the damaged portion. In some embodiments, the dressing guide can be used with the implant to restore the trimmed damaged alveolar bone.

In some embodiments, the step of using the dressing guide to cut the alveolar bone is different from using the same way to cut the teeth, wherein the support portion of the dressing guide contacts the alveolar bone to avoid dressing guidance The device moves. In some embodiments, the other aspects of the two steps are substantially similar. An embodiment similar to the dressing guide for cutting teeth, an embodiment for cutting the alveolar bone, the tooth is located close to the alveolar bone to be cut, and if any, the retention force can be supplied.

In an embodiment of the invention, the alveolar bone can be cut by moving the dental drill along different directions along the tool guide of the dressing guide, and different forms of implants, such as mesh, rod or mesh, can be visually required. Embed. While the implant procedure generally includes a hole-boring in the upper-lower direction of the alveolar bone, embodiments of the present invention allow the alveolar bone to be cut in different forms as desired when the dental drill is moved along the cutting guide of the dressing guide. section. Thus, in some embodiments, the alveolar bone can be cut in a horizontal or curvilinear direction or the like.

Moreover, in some embodiments, the method of creating a design to minimize intrusion cutting can be applied to laminated sheets produced for aesthetic purposes and to splints for stabilizing the teeth. Also, in some embodiments, crown bridges and crowns and bridges designed to minimize invasive cutting can also be created using trim guides. Moreover, in other embodiments, it may be created to avoid the food particles sticking to the teeth, which only need to minimize the intrusion cut. For the above purposes, it is important to determine the amount of intrusion that minimizes the cutting by minimizing the number of teeth that are easily jammed by the grouping of food particles when determining the appropriate axis of embedding. If the embedded shaft is not ideal, a large amount of cutting may be required.

Different forms of the complex can be produced using the dressing guide of the embodiment of the present invention. In some embodiments, because the expected cut shape of the tooth is predictable, a complexion can be created prior to using the trim guide to cut the tooth.

Moreover, in some embodiments, a trim guide can be used to embed a struts that include a crown bridge, any inlay or overlay, and root canal treatment on the teeth. Also, in some embodiments, the trim guide can be used to cut residuals of damaged teeth that are aesthetically pleasing or that are important for the stabilization of subsequent dental procedures. In other words, in some embodiments, the traditional complex, The inclusion of splints, laminates, and crown bridges, combined with trim guides, is still a viable solution.

Moreover, in accordance with embodiments of the present invention, a sufficient retention force can be created by minimizing the amount of intrusion of the cut teeth by scraping, holes or grooves such that the direction of the cut corresponds to the embedded complex axis. In some embodiments, the factors that allow for sufficient retention or aesthetic value to minimize invasive cutting can be easily determined. In some embodiments, the above factors may include, among other things, a preferred number and portion of teeth to be cut, and an embedded complex axis.

Splint

When the alveolar bone is damaged, the teeth supported by the damaged portion of the alveolar bone begin to shake. If the shaking of the teeth is neglected, the alveolar bone is further damaged and eventually the teeth are shaken off. In an embodiment, to avoid the above results, the moving tooth and its adjacent teeth can be connected via a fistula to stabilize the shaking of the teeth. The above-mentioned connection between shaking the teeth and its adjacent teeth is called a splint. In an embodiment, the alveolar bone located below the rocking teeth can be stabilized if the shaking tooth is fixed by the buccal patch. In the above embodiments, the stable alveolar bone strongly supports the teeth to avoid shaking. Further, in the above embodiment, in which the splint is fixed and shaken, the damage to the alveolar bone can be delayed, and the alveolar bone can be regenerated in some cases.

According to an embodiment of the present invention, the splint is installed, and the damage of the alveolar bone can be first diagnosed and the teeth of the splint are also determined. In some embodiments, the splint is conjugated to at least two adjacent teeth. In some embodiments, once the teeth of the splint are determined, the rough appearance of the splint is determined. The splint according to the embodiment has a structure that strongly unites the teeth without joining the crown structure. Thus, in some embodiments, the splint assembly does not include any crown structure that requires cutting of all of the occlusal surfaces and/or side surfaces. On the other hand, according to the embodiment, the proper engagement and side surfaces of the teeth for engaging the splint are cut using the dressing guide. In some embodiments, the plywood comprising a shape that closely conforms to the shape of the cut portion is configured to be strongly secured and joined.

Frontal splint

Referring to Figures 23A, 23B, 23C, in an embodiment, the splint 60 is engaged to securely rock the tooth and its adjacent teeth. To do so, the dressing guide 100 of the embodiment is coupled to the rocking tooth 70a and its adjacent teeth 70. In some embodiments, the dressing guide 100 includes a tool rail 120 for each tooth. In some embodiments, the tool rail 120 generally has an arrow-shaped guide channel. In some embodiments, an arrow-shaped tamper-retaining recess 86 is formed in each of the teeth, as shown in Figures 23B and 23C, as the dental drill moves along the guide channel of the tool rail 120.

Figure 23D depicts an embodiment in which the indentation fixation groove 86 is formed in the tooth as viewed from the inlaid shaft 76. Referring to Fig. 23F, the splint 51 of the embodiment has a unitary structure in which each tooth includes a fixing projection 58. In some embodiments, the securing projections project from and extend over the inlaid turns. In an embodiment, the retaining projections 58 are embedded in their opposing tamper-evident recesses 86 and are secured such that the splint tamper 51 is secured to the teeth (see Figure 23C). As such, in an embodiment, the rocking tooth 70a is coupled to its adjacent teeth, substantially reducing the rocking motion but allowing the supporting alveolar bone to regenerate.

In the embodiment shown in Figures 23B, 23D and 23F, four securing projections 58 project and extend over the inset shaft 76. Figure 23D depicts the centerline 87 of each of the fixed recesses 86 depicting a dental drill shaft that rotates along the tool rail 120. Figure 23E is a cross-sectional view of the embodiment of the securing recess 86 along line 88 perpendicular to a centerline 87 at a fixed point. In the above embodiment, the four tamping fixing grooves 86 are visible along the entangled insertion axis 76.

In the embodiment shown in Fig. 23E, no undercut is present in the interior of the tamping fixing groove 86 in the embossed insert 76. In an embodiment, the side wall 80 of the tamper-retaining recess is inclined in the entangled shaft. The angle a between the side wall 80 and the line 78 parallel to the entangled embedded shaft 76 is in the range of from about 0.3 to about 3 . In an embodiment of the invention, the angle a is about 0.4, about 0.5, about 0.6, about 0.7, about 0.8, about 0.9, about 1 , about 1.1, about 1.2, about 1.3. , about 1.4, about 1.5, about 1.7, about 1.9, about 2, about 2.3, about 2.7, about 3, about 3.5, or About 4°. In other embodiments, the angle a can be within the range of either of the above numbers. In some embodiments, the tamper-retaining recess having a relatively large slope angle can be more easily embedded into the fixed projection and can have less retention than a relatively small slope angle.

In an embodiment, the four fixed grooves 86 shown in Figure 23B can be cut by a single drill. In some embodiments, when a single dental drill cuts all of the fixed fixation projections 86, the angles of the side surfaces of each of the grooves are equal. In contrast, in other embodiments, each of the tamper-evident grooves 86 can also be cut with a different drill.

As shown in Fig. 23, the teeth can be cut according to other embodiments of the embedded shaft different from the Fig. 23F.

Posterior teeth

Figures 18A, 18B, 18C, and 116-123 show the splinting of the different posterior teeth. In the embodiment depicted in Figures 18A, 18B and 18C, portions of the tongue and proximal surface are cut and the splint 51 is engaged. In the illustrated embodiment, the splint 51 is engaged to immobilize the tooth 70a to its adjacent teeth without damaging the contact point between the two teeth.

In the embodiment as shown in Figures 116-118, the dressing guide 100 includes a tool guide 120 for cutting the tongue, the distal and buccal surfaces of the first molar 70a, the tongue of the second molar, the intermediate and buccal surfaces, and The surface of the tongue of the front molar. In the illustrated embodiment, the tool rails 120 are all coupled such that the dental drill 200 is inserted into the tool hole 124 up and down and moves along the tool rail 120 for cutting. Although the contact point between the two molars is cut in this embodiment, since the splint 5151 of each tongue and the buccal surface (facing each other) is used, the retention of the sputum is stronger than that described in Fig. 18. An embodiment.

In the embodiment illustrated in Figures 119-121, the dressing guide 100 includes a tool guide 120 for cutting the tongue of the second molar, the distal and buccal surfaces, the tongue and cheek surface of the first molar, and the premolar The surface of the tongue. In the embodiment shown, the tool rails 120 are all connected such that the dental drill 200 is embedded The tool hole 124 is located adjacent to the front molar and moves along the tool guide 120 for cutting. In this embodiment, the splint 51 can be joined without the need to damage the contact points between two adjacent teeth. Further, since the tongue and the buccal surface of each of the molars are used, they face each other, and the splint 51 is joined, and the holding force is stronger than that of the embodiment shown in Fig. 18.

In an embodiment, as shown in paragraphs 122-123, the cutting occurs at the tongue of the second molar, the middle and buccal surfaces, the portion of the tongue and proximal surface of the first molar, and the tongue and proximal surface of the two premolars. Part of it. In the illustrated embodiment, the cheek surfaces of the two pre-caries and the first molar are not cut. In order to increase the holding force of the splint, the enthalpy is embedded between the near midplane of the first molar facing each other and the distal midplane of the second premolar. The 赝 is configured to use the tongue and cheek surface of the second molar. Therefore, although the contact point between the second premolar and the third and second molars can be damaged according to this embodiment, sufficient retention can be obtained.

As such, the multiple posterior teeth can also be joined using a splint, and the cutting guide can be used in accordance with the various embodiments described above in order to engage the posterior colloid.

Dental procedure using a dressing guide

In an embodiment, the dental procedure using the dressing guide includes determining a dental procedure to be performed, collecting three-dimensional shape data about the tooth, selecting a final desired shape with a refurbished installation, designing the shape of the tooth after cutting, designing, or The steps of selecting a dental drill, designing a dressing guide, manufacturing a tamper, manufacturing a tool, making a dressing guide, cutting a tooth, and installing a tamper.

Decide on dental procedures and collect data on patients' teeth

Referring to Fig. 105, when the patient visits the dentist's office, the dental operator examines the patient and decides on the dental procedure (S100). In an embodiment of the invention, the dentist decides to include a procedure for installing a tooth that is applied to the patient's mouth. At the same time, the dental operator roughly considers the general shape of the desired complex. The specific recovery is not designed at this point. For example, if the dentist decides to use a bridge, the dentist can Then decide how much and which tooth to use as an arch.

In the embodiment, three-dimensional data of the shape and/or the shape of the mouth of the patient's teeth are then collected (S200). In some embodiments, collecting patient tooth data can occur before the dental operator diagnoses the patient or determines the dental procedure. The collection of patient dental data can occur in different places using different methods. In an embodiment, the dental operator uses the impression to obtain data on the shape of the mouth of the patient. The dental operator or dental laboratory uses an impression to form a model containing the shape of the mouth of the tooth. In an embodiment, the shape of this model is scanned and digitized using a three-dimensional scanner. In some embodiments, the scanning and/or manufacturing of the model occurs at the dentist's office. In other embodiments, the scanning and/or manufacturing takes place outside of the dentist's office, such as a laboratory. In the above embodiments, the dental operator sends an impression to the dental laboratory or other location where the scan and/or manufacture is performed. In the above embodiments, the dental laboratory or other location creates an impression based model and digitizes the data. Additionally, in other embodiments, the dental operator can use an oral scanner to directly scan the oral shape and generate data, as well as send data to the dental laboratory.

In other embodiments, the collection of dental data can occur in a dental laboratory outside the dentist's office or elsewhere. Impressions can be generated from data collected in this manner and sent to the dental operator, and the dental operator can determine the dental procedure based on these images.

Select the desired tooth shape after the installation

In an embodiment, once the dental procedure is determined, the data of the original tooth shape is processed after the tampering to produce data relating to the expected tooth shape and a corresponding image is produced. In an embodiment, the data and images of the expected shape are produced in different complex forms. The resulting image is sent to the patient. In some embodiments, after the dental procedure is installed, at least one image of the intended shape of at least one tooth can be posted via email, text message, mail, manual delivery, video conference, meeting with the patient or his agent, Deliver appropriate communication to the patient on the Internet site, or any recent or future development. In an embodiment, the patient confirms the image and selects the suggested shape One. After installation, the desired shape is selected to be the final tooth shape.

Designed intended tooth shape

In some embodiments, a CAD/CAM system is used to model and design the post-cut shape of each tooth before or after the installation determines the desired shape of the tooth. In an embodiment, during the modeling process, the three-dimensional image of the tooth to be cut is tilted in multiple directions, and one direction is selected from different selections. In an embodiment, based on this direction, the surface of the tooth to be cut and the direction of the embedded axis or the complex are determined later. In an embodiment, the corresponding basic structure or cutting conditions or parameters corresponding to the teeth are entered into the computer program based on the selected direction. In an embodiment, the program allows the design of the desired tooth shape on the computer and displays the finished image on the screen. As described in Figures 106-109, in some embodiments, three-dimensional data regarding the intended shape of the cut tooth can be presented in advance and displayed on a monitor as an image. In an embodiment, the portion to be cut and the amount to be cut are determined based on the desired tooth shape.

Determining the embedded axis

According to an embodiment, the dental operator selects the inlaid shaft to provide sufficient space for the reduction of the number of teeth to be cut. More specifically, in some embodiments, the CAD/CAM computer program allows for tilting of a three-dimensional image of a patient's teeth in different directions. In some embodiments, the program may display portions of the teeth to be cut in each oblique direction based on the selected parameters. In an embodiment, the above parameters may include the angle between the direction and the cutting surface (see the angle a of Figures 92B and 92C) and the position of the lower portion to be cut (e.g., the boundary between the gums and the teeth). In the above embodiment, if the three-dimensional image is tilted in a specific direction and the line of the angle α (including 0 degrees) in the direction of the top of the direction is reversed so that the line conforms to the boundary between the gums and the teeth, the above line will be displayed. The side surface of the tooth to be cut. If this step is repeated at all points on the boundary between the gums and the teeth, the number of tooth cuts (three-dimensional volume cut or two-dimensional depth cut) can be displayed on the screen when a particular direction is selected. In addition, by repeating this step in different directions of the three-dimensional image, the user The amount of teeth to be cut can be seen depending on the embedded axis. Based on this, when reducing the number of tooth cuts, the embedded shaft can be decided to obtain a relief with the desired topography.

Design recovery

In the embodiment, the tooth is expected to be determined after the installation is completed, and the design is designed based on the above-described expected shape (S700). As shown in the flow chart of Fig. 105, the design is repeated and it is decided that the expected tooth shape can occur simultaneously, but the invention is not limited thereto. In other embodiments, it is contemplated that the shape of the teeth can be determined prior to design failure, and vice versa. Moreover, in another embodiment, the complex shape and the desired tooth shape can be determined simultaneously by examining how the shape of one affects other shapes. For example, in an embodiment, this can be done by viewing the additional retention force to change the shape of the complex and viewing the corresponding desired tooth shape.

Design dental drill and guiding device

In an embodiment, after the desired tooth shape design, the dental drill is designed based on the expected tooth shape. In the design of the dental drill according to the embodiment, the factors to be considered include the diameter of the cutting head and the distance between the end of the cutting head and the guiding projection (S400). In some embodiments, the design of the dental drill may also involve the use of a CAD/CAM system. Although the dental drill is designed in the above embodiment, several dental drills can be previously manufactured or designed and appropriately selected from the viewpoint of the teeth to be cut.

In an embodiment, after designing the desired tooth shape and determining the dental drill, the moving path of the dental drill is determined using a CAD/CAM system (S500). In the described embodiment, the design of the channel can occur as if by the tool design showing how the other is affected. In the embodiment, after the passage is determined, the dressing guide of the tool guide having the shape of the passage is designed (S600). As shown in Figures 100-115, in an embodiment, the design of the trim guide is detectable as a graphical image. According to an embodiment, the mounting portion of the dressing guide is designed using factors such as arch tooth data, adjacent tooth data, and gum data. In some embodiments, the number and shape of the dental drill inlet and the cooling water The number and shape can also be designed.

In the above embodiment, the dental drill can be designed first, and the dressing guide is then designed, but the design of the drill and dressing guide can occur simultaneously by considering how they affect each other.

Manufacture of tamping, guiding devices and dental drills

In the embodiment, the tampering is manufactured according to the design of the tampering (S800), and the dressing guiding device is manufactured according to the design of the trimming guiding device (S620).
