Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surgical guide for a dental implant,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surge guide, and more particularly, to a surge guide for dental implant surgery and a method of manufacturing the same, in which a sorting guide is provided so that a surge guide for guiding an implant procedure is installed at an accurate position inside the mouth.

Generally, an implant refers to a substitute for replacing a human tissue when the original human tissue is lost, but refers to implanting an artificial tooth in the dentistry.

In detail, in normal prostheses or dentures, the surrounding teeth and bones are damaged over time, but the implants can prevent damage to surrounding tooth tissues and can be used stably because there is no secondary tooth decay factor. In addition, since the implant has the same structure as the natural teeth, there is no pain or foreign body sensation of the gums, and it is advantageous that the implant can be used semi-permanently.

In the meantime, the implant treatment is performed by forming a perforation in the alveolar bone using a drill and placing the fixture in the perforation. Procedures for forming the perforation and implanting the fixture are different for each patient. This is because the position, depth, and orientation of the implant should be determined in consideration of various factors such as the patient's tooth condition, the position of the tooth requiring the implant treatment, and the condition of the alveolar bone of the patient.

Thus, the drilling operation for drilling the alveolar bone has difficulty in not only the beginner but also the experienced person, it is very difficult to precisely measure the depth and direction in the process of work. Accordingly, an auxiliary device called a surgical guide is used to grasp the exact position and direction to perform the drilling operation.

In detail, the surgeon guide includes a fixing groove portion formed in the mouth of the subject and a guide hole formed corresponding to the positioning position and direction of the fixture. That is, when the fixation groove is drilled along the inner circumferential surface of the guide hole in a state where the fixation groove is formed in the mouth cavity of the subject, the perforation can be formed corresponding to the direction and depth in which the fixture is to be placed.

However, if the surge guide can not be installed at the correct position, there is a problem that the position where the perforation is formed is deviated from the position where the perforation is first established. In particular, in the case of a patient having a large amount of tooth loss or edentulous, even if the fixing groove portion is manufactured so as to be in conformity with the outer surface of the gum, there is a problem in that it is practically difficult to fix the correct mounting position due to fluidity of the gum.

This causes a problem that the puncturing direction and the fixture placement position are performed differently from a predetermined position. In addition, if the perforation and fixture are not formed at predetermined positions as described above, the surgeon feels uncomfortable after the implant procedure. In addition, there is a problem that the preparation is interrupted due to interference between the implant implant and the surrounding teeth, causing damage and pain to the surrounding teeth and gums. Further, when the implant re-treatment is required due to such a problem, there is a problem that a lot of re-operation time and cost are incurred due to bone loss occurring in the wrong procedure.

FIG. 2 is a schematic view of a surge guide according to an embodiment of the present invention. FIG. 3 is an exemplary view showing a state where a surge arrester according to an embodiment of the present invention is installed inside an oral cavity, and FIGS. 4A and 4B are views showing an A portion of FIG. 3. FIG.

In the meantime, the dental implant treatment is performed by forming a hole in the alveolar bone using a drill, and placing the fixture in the hole. At this time, an auxiliary device called a surgical guide is used so as to grasp the exact position and direction in which the drilling operation will be performed.

That is, if an implant procedure plan is established according to the condition of the inside of the mouth of the patient, the surge guide is prepared so as to guide the placing position and direction of the preparation to be prepared according to the established procedure plan. Then, the manufactured surge guide can be installed inside the oral cavity to guide a practitioner's procedure, that is, the direction and depth of the drill or fixture when the fixture is placed.

On the other hand, the implant can be understood as including a fixture, a crown, and an abutment that mediates the crown and the fixture in an implant procedure for replacing a lost tooth. Here, the crown can be manufactured corresponding to the vertical height and the dentition of the subject, and the fixture and abutment for the crown can be selected and used for implant treatment. Of course, depending on the case, the abutment may be produced individually corresponding to the dentist's dentition.

In detail, as shown in FIGS. 1 to 4B, a surgical guide for dental implant surgery showing alignment criteria according to the present invention and a method for manufacturing the same are performed as follows.

First, the inside of the mouth of the subject is orally scanned to obtain an oral scan image, and the upper and lower jaws (1, 2) are CT images to obtain a CT image. At this time, the alignment line is virtually arranged along the profile connecting the opposing outer side faces of the gingival section including the tooth placement target portion indicated in the oral scan image and the predetermined visible standard index on the inner side (s10). Here, it is preferable that the tooth placement target portion is a portion which is intended to perform the implant operation because natural teeth are lost in the maxilla (1) to the mandible (2).

In detail, the oral scan image is obtained while moving the oral scanner along the internal profile of the subject and includes three-dimensional external information of the oral cavity. Here, the three-dimensional outline information is preferably understood as the crown of the remaining tooth in the oral cavity including the tooth placement target portion and the shape of the outside of the gum.

In this case, the oral scan image may include a primary scanning image in which a three-dimensional outer shape of a tooth placement target portion is orally scanned, and a secondary scanning image in which an opposite tooth side of the tooth placement portion is orally scanned. In addition, the secondary scanning image may be obtained by scanning an occlusal-scanned occlusion scanning image in a state where the upper and lower jaws 1 and 2 of the subject have been occluded, and a three-dimensional outer surface of the opposing tooth Lt; RTI ID = 0.0 > a < / RTI > scan. At this time, in the occlusion scanning image, the vertical height according to the occlusion of the upper and lower teeth (1, 2) can be confirmed.

The scanning images may be automatically or manually superimposed on a common area between images through a computer-based image processing process. At this time, the common area may be a part of the remaining teeth, or a separate overlapping reference point may be set in some cases. Moreover, the common area may be a registration marking means such as a reference marker installed inside the oral cavity before performing the image acquisition operation.

The primary scanning image and the spacing scanning image may be arranged corresponding to vertical heights, respectively, as the common areas of the occlusion scanning images are overlapped with reference points. Accordingly, it is possible to obtain an integrated scanning image in which the three-dimensional contour information of the tooth placement target portion and the three-dimensional contour information of the contour tooth are arranged in a state in which the vertical height of the subject is considered.

In addition, the CT image includes two-dimensional and three-dimensional internal tissue information obtained by CT imaging the upper and lower jaws (1) and (2). Here, the two-dimensional and three-dimensional internal tissue information is preferably understood as information such as the shape of the alveolar bone and the bone density of the inside of the subject. In addition, the CT image may further include the above-mentioned matching marking means.

At this time, the order of acquiring each image may be changed flexibly according to the practitioner's procedure style. For example, it is possible to acquire the CT image through the CT imaging first, obtain the ORAL scan image, and the modification of the image acquisition sequence falls within the scope of the present invention.

In the meantime, the alignment scan line may be arranged along the visual reference index. Here, the visible reference index is preferably understood as a reference area in which a practitioner can visually confirm the gingiva including the tooth placement part and guide the installation of the surge guide later.

Specifically, the visible reference indicator is set to a frenum connecting between the lips and the gums or between the tongue 3 and the gums within the oral cavity, such as the upper platelets 1a, lower platelets 2a, . Furthermore, the platelets 1a, 2a and 3a are formed along the midline ML of the oral cavity. The alignment mark 14 formed at a position corresponding to the alignment line of the surge guide 10 corresponds to the positions of the platens 1a, 2a, and 3a, Can be guided to be installed at an accurate position.

   In addition, the visual reference index may be set as an arrangement surface (k) between a pair of teeth (t1, t2) mutually adjacent among teeth remaining in the oral cavity. Specifically, the pair of teeth t1 and t2 are arranged such that mutually opposed faces are substantially in contact with each other or form a minute gap. At this time, since each of the teeth is substantially fixed to the alveolar bone, the array surface k can be set as a visible reference index.

Further, since the teeth are formed in a profile narrowing from the upper end of the crown to the root direction, the flexible tissue of the gums is filled in the gap between the pair of teeth t1 and t2. Accordingly, since the gums are displayed as a wedge shape between the pair of teeth t1 and t2, they can be used as a clear visible reference index.

Particularly, since the anterior and posterior teeth 1 and 2 are formed in pairs on the left and right with respect to the midline ML, the surgeal guide 10 is installed at the correct position as in the case of the platelets 1a, 2a, And can be a visible reference indicator that leads to As a matter of course, in the case of a subject who has lost the transposition according to circumstances, a pair of consecutively arranged teeth between teeth may be set as the visible reference index.

That is, the visual reference index is defined by the small platelets (1a, 2a, 3a) and the pair of teeth (t1, t2), which are predetermined on the inside and the inside of the mouth portion, (K) between the inner surface and the outer surface. The alignment line may be arranged in a virtual arrangement along a profile connecting the visible reference indices respectively set to the outer side surface and the inner side surface. At this time, the alignment line may be a reference for designing the alignment markers 14 when designing a surge guide 10 to be described later.

Here, the outer surface of the inside of the oral cavity is preferably understood as the outer surface of the tooth portion of the teeth, which is exposed to the outside while lifting the lips, and the teeth of the teeth remaining thereon. The inside surface of the oral cavity is preferably an inside surface of the gingival portion and a portion of the crown portion remaining thereon, which portion is opposed to the outside surface inside the oral cavity.

On the other hand, a three-dimensional occlusion guide image is obtained by matching the orthal scan image and the CT image on the basis of the matching markers matched with each other (s20). Since the OR scan image includes the primary scanning image and the secondary scanning image, it is preferable that the OR scanning image has the same meaning as the integrated scanning image.

Specifically, a portion of the oral scan image including three-dimensional outer shape information inside the oral cavity and a pair of a pair of the CT image including two-dimensional and three-dimensional internal tissue information inside the oral cavity are matched to the comparison region Setting. At this time, the comparison area may be a part of the remaining tooth, or a separate matching standard may be set in some cases.

Furthermore, the comparison area may be the matching marking means such as the reference markers. It is preferable that the matching marking means is formed of a radiopaque material so as to be attached to the inside of the oral cavity before acquiring the respective images and to be displayed in both the oral scan image and the CT image.

In detail, the reference marker is attached to the inside of the oral cavity in a shape having a constant volume such as a cylinder or a polygonal column, and can be used as a matching reference when the orthal scan image and the CT image are superimposed on each other. Of course, in some cases, the matching marking means may be provided in the form of a reference wire which is plastically deformed along the dental arch profile inside the oral cavity. That is, by setting the exposed reference surface of the reference marker or the reference wire as a matching reference, the OR scan image and the CT image can be easily overlapped.

Furthermore, the registration marking means may be attached directly to the interior of the mouth of the subject, but may be attached to the object corresponding to the interior shape of the mouth to prevent the problem of the position of the registration marking means being not fixed due to fluidity of the gums have.

For example, the matching marking means may be attached to an outer surface of a tray installed to obtain an impression of an inside of the mouth of the subject, and the tray may be installed inside the oral cavity of the subject to obtain images. Alternatively, the matched marker means may be attached to the outer surface of the denture used by the client in place of the natural teeth, and the denture may be installed inside the mouth of the client to acquire each image.

In this case, when the orthal scan image and the CT image are originally combined, the three-dimensional occlusion guide image including the three-dimensional outer shape information of the inside of the subject and the two-dimensional and three-dimensional internal tissue information can be obtained simultaneously.

In detail, the main matching overlaps the OR scan image and the CT image and sets a common portion as the comparison area. Then, each image is corrected so that the uppermost portion and the outermost portion of the comparison region, which are respectively displayed in the ORAL scan image and the CT image, coincide with each other.

At this time, the ORAL scan image and the CT image are converted into three-dimensional vector data and displayed, and the first difference map having a small error can be obtained by superimposing the comparison area displayed in each image. Then, an image correction operation is performed in the image matching process through the difference map, so that the highly precise and matched three-dimensional occlusion guide image can be obtained.

Here, the degree of association between the images means that similarity between the ORAL scan image and the CT image is expressed by a combination error between the two images. In detail, the lower the absolute value of the above-mentioned nulling error, the more the two images coincide with each other and overlap with each other. On the contrary, the higher the absolute value of the above-mentioned combination error, the more the two images are overlapped.

That is, when the operation of increasing the degree of association by superimposing the oval scan image and the comparison area set on the CT image is performed, the three-dimensional outer shape information and internal organization information inside the mouth appear on the respective images, Lt; / RTI >

At this time, as the degree of fit is decomposed and output for each color, the operator can quickly and intuitively judge the accuracy of the image registration result. As a result, a rapid image processing operation for the implant procedure is possible, and a subsequent correction operation for acquiring an accurate three-dimensional occlusion guide image can smoothly proceed.

In addition, since a precise operation plan can be established through the simulation operation on the 3D-guided guide image, a separate remeasurement process is not required for each implant step such as perforation formation and installation of each implant.

On the other hand, the surge guide 10 installed inside the oral cavity of the subject is designed and manufactured based on the three-dimensional occlusion guide image. The surge guide 10 includes a body portion 11 having an inner surface formed with a fixing groove portion 12 formed in the inner cavity profile and a guide hole 13 formed through the body portion 11 . The alignment mark 14 may be formed at a position corresponding to the alignment line so as to guide the precise position of the surgeal guide 10 in the oral cavity (s30).

In detail, the three-dimensional occlusion guide image includes the three-dimensional contour information of the oral cavity and the oral scan image including the alignment line image virtually arranged along the visible reference index. The CT image matched with the ORAL scan image and the matching mark includes two-dimensional and three-dimensional internal tissue information in the oral cavity.

Here, the shape of the fixing groove 12 of the surge guide 10 can be designed based on the three-dimensional contour information of the ORAL scan image. In detail, the fixing groove portion 12 corresponds to the outer surface profile of the inside of the mouth including the tooth placement target portion, and can be set to a shape that is formed with the outer surface of the gums and the remaining teeth. Accordingly, the surgeal guide 10 can be substantially fixed to the inside of the oral cavity since the surgeal guide 10 is fitted into the oral cavity including the tooth placement target portion.

The guide holes 13 penetrate corresponding to the implant treatment position and the placement direction. At this time, the position and direction of the guide hole 13 may be previously set through the three-dimensional occlusion guide image.

In detail, the size and shape of the crown and the orientation of the fixture can be set through the three-dimensional outer shape information and the internal tissue information of the oral cavity superimposed on the three-dimensional occlusion guide image. The position and the direction of the guide hole 13 can be set on the 3D-guided guide image in accordance with the setting direction of the fixture set as described above.

The guide hole 13 may be directly formed in the body 11 but may be formed in a guide sleeve 13a inserted into the body 11 to prevent deformation when the contact hole 13 is in contact with a drill or the like. .

In detail, a through hole is formed in the body part 11 in correspondence with the direction in which the fixture is placed, and the guide sleeve 13a can be inserted and fixed in the through hole. At this time, the guide sleeve 13a may be formed as a base portion in which the guide hole 13 is formed and a protrusion portion for fixing the position of the guide sleeve 13a. Accordingly, the treatment instrument can be guided more stably during the implant treatment.

The alignment guide 10 guides the position where the surge guide 10 is installed in the oral cavity so that the precise procedure is guided through the guide hole 13 when the fixing groove 12 is installed in the oral cavity. The marking portion 14 is preferably formed.

Specifically, the surge guide 10 is designed and manufactured through the matching of the oral scan image and the CT image obtained with respect to the interior of the subject's mouth, and is installed inside the oral cavity. At this time, even if the subject has little or no residual tooth or is made of a profile in which the fixing groove 12 is formed with the inside of the oral cavity, the fluidity of the gum can not be fixed at a substantially correct position.

In order to precisely guide the fixture according to the implant procedure plan by guiding the surge guide 10 to the correct position in the oral cavity, the alignment markers 14 are formed on the body part 11 do.

Here, the body portion 11 may be formed of a synthetic resin material to be projected inside. Accordingly, even when the surgeon's guide 10 is installed in the oral cavity, the operator can visually confirm the internal shape of the oral cavity projected through the body portion 11 easily.

Preferably, the alignment markers 14 are designed on the three-dimensional occlusion guide image in a position corresponding to the alignment line that is virtually arranged when the surge guide 10 is three-dimensionally designed.

At this time, it is preferable that the alignment markers 14 are formed in at least one of grooves or protrusions. It is preferable that the alignment mark 14 is extended to cover the outer surface 11a and the inner surface 11b of the body 11. [

In detail, the 3D scan image is superimposed on the 3D scan image and the CT scan image, and the alignment line is arranged along the visual reference index of the OAL scan image. When the surge guide is three-dimensionally designed from the three-dimensional occlusion guide image, the alignment markers 14 can be designed at positions corresponding to the alignment lines.

In this case, as shown in FIG. 4A, the alignment markers 14 may be formed in a protruding shape protruding in the outer direction of the body part 11 along the alignment line. Here, the protruding alignment mark 14 may protrude from the outer side of the inside of the oral cavity to a profile surrounding the inside of the oral cavity.

Alternatively, as shown in FIG. 4B, the alignment mark 114 may be formed in a recessed shape recessed inward of the body 111 along the alignment line. Here, the groove-shaped alignment markers 114 may be recessed from an outer surface of the inside of the oral cavity to a profile that surrounds the inner surface of the oral cavity. Further, the groove-shaped alignment markers 114 may be further filled with a predetermined color coating material so as to easily distinguish the body part 111 from the alignment markers 114.

As a matter of course, the alignment marking portion may be formed on the upper side of the body portion of the surge guide so that the coating material is applied at a position corresponding to the alignment line. That is, if the indicator is displayed in a form that can be aligned with the visible reference indicator on the outside of the body portion of the surge guide, the form is not limited.

In addition, the alignment markers 14 and 114 may be formed at positions corresponding to the midline ML, but they may be formed to correspond to a pair of teeth arranged at any one side of the oral cavity, Such variations are within the scope of the present invention.

The outer surface side (inner surface) of the oral cavity including any one of the upper-order phallus 1a, the lower phallus 2a, and the pair of adjacent tooth-outer-side arrangement surfaces k projected through the body portion 11 Visible reference indicators can be visually confirmed. In addition, it is possible to visually confirm the inner visual reference index including any of the glenbrae 3a projected through the body portion and the pair of inter-tooth arrangement surfaces k adjacent to each other.

The surge guide 10 is arranged at an accurate position inside the oral cavity by aligning the alignment markers 14 along the profile connecting the outer surface visible reference index and the inner surface visible reference index, .

Further, the surgeon 10 can be firmly fixed by fastening a fixing pin or the like to the side surface of the surge guide 10 disposed at the precise position as described above, and then the implant procedure can be performed.

The surge guide 10 may be formed by applying a dental resin or the like made of a transparent material to the fixing groove 12 or attaching the alignment mark 14 to the portion excluding the portion to which the visual reference index is projected. Dental resins may also be applied. When the surge arrester 10 is installed in the oral cavity, the dental resin may be pressed between the oral cavity and the fixation groove to be corrected to the contour profile of the tooth placement target portion. As a result, the gap between the surge guide 10 and the inside of the oral cavity can be compensated by the dental resin, so that the fixing force of the surge guide 10 can be further improved.

Accordingly, the present invention can easily design and manufacture the surgeal guide 10 that acquires the oral scan image and the CT image of the inside of the oral cavity and guides the implant surgery precisely based on the matched three-dimensional occlusion guide image have. Thus, the number of times of visits by the physician and the procedure of the practitioner are significantly shortened, and the base technology device of the implant that can be completed in a short period of time can be provided.

At this time, in order to guide the position where the body part 11 is installed in the oral cavity, the alignment markers (not shown) are arranged at positions corresponding to the alignment lines set along the visible reference mark, 14 may be formed. The alignment marking portion 14 is formed by extending the outer side surface 11a and the inner side surface 11b of the body portion 11 so as to correspond to the outer side visible standard indicator and the inner side visible standard indicator simultaneously .

Accordingly, the surge guide 10 is installed at the precise position inside the oral cavity, so that the perforation and fixture placement work for the subsequent implantation procedure can be accurately performed. As a result, precise and precise placement of the implant according to the implant treatment plan can be achieved, which can significantly improve the patient's satisfaction with the procedure.

At this time, the alignment mark 14 formed to surround the outer side surface 11a and the inner side surface 11b of the body part 11 and the outer side surface and the inner side surface of the oral cavity can be visually checked, It is possible to arrange the surge guide 10 at an accurate position.

Further, since the body part 11 is formed of a material to be projected inside, the visual reference indicator can be easily checked through the body part 11 while the surge guide 10 is installed inside the oral cavity The installation property can be remarkably improved.

In addition, the design of the crown and the selection of the abutment and the fixture corresponding to the crown can be performed at the same time as the surge guide 10 is designed and manufactured through the three-dimensional occlusion guide image. That is, it is possible to obtain accurate information about the interior of the oral cavity by simply acquiring and matching images of the inside of the mouth without a separate impression-making process. Also, it is possible to simultaneously design and manufacture the implant for implant treatment and the surge guide 10 for guiding the implantation through the oral cavity information included in the image.

Accordingly, even in the case of a patient who has a large amount of tooth loss or a large amount of teeth lost and fluidity of the gum is high, the surgeon 10 can be prevented from being damaged, The visibility reference index can be easily confirmed through the probe 11 to accurately determine and fix the installation position, so that accurate fixture placement according to the implant procedure plan is possible.

Further, a profile connecting the visibility reference index, which is set from mutually opposing inner and outer sides of the platelets (1a, 2a, 3a) and a pair of teeth-arranged surfaces (k) calculated from the oral scan image, The surgical guide 10 can be disposed at an accurate position by a simple operation of mutually aligning the alignment markers 14 formed so as to cover the outer side surface and the inner side surface of the base plate 11,

As described above, the present invention is not limited to the above-described embodiments, and variations and modifications may be made by those skilled in the art without departing from the scope of the present invention. And these modifications fall within the scope of the present invention.
