Description

Universal partial bite guide for measuring occlusal vertical dimension}

The present invention relates to a universal partial bite guide for measuring vertical diameter, and more particularly, to a universal partial bite guide for vertical diameter measurement with improved usability.

In general, dental restoration refers to artificial periodontal tissue in the oral cavity that artificially restores appearance and function by replacing missing teeth.

In detail, when natural teeth are left in a lost state, distortion of the dentition occurs in adjacent teeth and antagonistic teeth of the missing teeth, resulting in deformation of the facial shape, and reduced masticatory function, increasing discomfort in daily life. Furthermore, when the natural tooth is lost for a long period of time, the alveolar bone surrounding the lost tooth is absorbed into the body, making it difficult to install artificial periodontal tissue.

At this time, the dental restoration is installed in the oral cavity to restore the chewing function and prevent deformation or damage of the opposing tooth or the remaining tooth on the target arch side requiring a dental restoration. Here, the dental restoration may be provided as an artificial crown that is individually matched to the missing tooth, or may be provided in the form of a dental prosthesis that replaces a plurality of missing teeth on the arch side of the target arch or the entire missing tooth. These dental restorations are made of titanium, etc., which are not rejected by the human body, to replace the lost tooth root, and are fixed in the oral cavity through a fixture (fixture) implanted in the alveolar bone.

On the other hand, in order to design the dental restorations suitable for each patient and install them in an accurate position, accurate and precise oral information is required. To this end, internal tissue information such as oral surface information and alveolar bone shape/bone density are required together. Therefore, an image registration process of obtaining scan images and CT images corresponding to the upper and lower jaws of the patient and aligning and shaping them corresponding to the vertical height is required.

At this time, in order to prepare an implant suitable for the oral cavity of the patient and set the height of the dental restoration, the CT image is preferably obtained by CT imaging in a state in which the upper and lower jaws are occluded with respect to the vertical dimension of the patient.

However, when only the anterior teeth partially remain, there is a problem in that the upper and lower anterior teeth are excessively engaged according to the anatomical dentition structure. Due to this, the exact vertical dimension of the patient cannot be calculated, and the height of the final dental restoration is set lower than the vertical dimension suitable for the patient, and there are problems such as not being accurately occluded and straining the temporomandibular joint.

On the other hand, a biting means for calculating the patient's vertical dimension has been partially disclosed. Such a bite means includes a tray for impression taking, a wax rim formed in an arc shape as a whole along the dental arch of a target arch, or a custom splint individually designed and manufactured according to a patient.

However, such a conventional bite means is substantially provided in an arc shape corresponding to the overall shape of the dental arch, and thus is formed to have a predetermined thickness as a whole. Because of this, it can be easily used when calculating the vertical dimension of substantially edentulous patients, but in the case of partially edentulous patients, interference occurs between the remaining teeth and the opposing teeth due to the thickness of the bite means. Therefore, in the case of partially edentulous jaws, there is an inconvenience in that a conventional bite means must be cut or divided to be used.

At this time, when the bite means is cut or divided to partially occlude the oral cavity, there is a problem in that it is difficult to fix the bite means to the oral cavity. For this reason, when the patient opens or moves the bite means while holding the bite means in his mouth, the position of the bite means moves/displaces, making it difficult to calculate an accurate vertical diameter.

Moreover, in the case of conventional custom splints, design processes and costs increase due to individual designs according to patients, and there is a problem in that economic feasibility decreases due to an increase in overall cost and period of dental restoration.

In order to solve the above problems, an object of the present invention is to provide a universal partial bite guide for measuring vertical diameter with improved usability.

In order to solve the above problems, the present invention is a bite guide for measuring the vertical dimension of a partially edentulous patient in which the posterior tooth of the target arch is missing, and is extended in correspondence with the preset molar side standard tooth line, An occlusal base whose thickness is adjusted based on the depth of an occlusal scar formed by pressing and deforming corresponding to the outer end of the occlusal object on the opposing arch side to be occluded with the target arch is laminated on the outer surface, and is provided on the inner surface on the posterior side of the target arch. A pair of base bite units formed with a seating surface that is concavely recessed to surround a gum ridge and pressurized and corrected to match the surface of the posterior gum ridge in response to occlusal pressure; and a pair of the base bites to form an exposure space in which the remaining teeth on the anterior side are exposed so that the pair of the base bites cut by the remaining teeth on the anterior side of the target arch are aligned and arranged at both posterior teeth at a constant interval at the same time. It is integrally formed by interconnecting the lingual surface side of the occlusion base, and the surrounding tissue adjacent to the gum ridge on the inner surface to align the position of a pair of the bas bite parts so that each of the bas bite parts on which the bite base is stacked faces the occlusion object. A molded surface that is pressure corrected to be molded to the surface is formed and includes an alignment extension part integrally formed with the base bite part and the base bite part made of a synthetic resin material having rigidity, so that a correction interval is secured between the upper and lower jaws. It is formed to a thickness less than a predetermined average molar height, so that the sum of the thicknesses of the occlusal base and the base bite portion exceeds a predetermined standard vertical diameter so as to support the gap between the bite object and the outer surface of the base bite portion. Characterized in that Provides a general-purpose partial bite guide for vertical diameter measurement.

Through the above solution, the present invention provides the following effects.

First, since the base bite part is provided to support the posterior spacing of the patient who has lost teeth, it is possible to accurately measure the vertical dimension by preventing excessive occlusion of the remaining teeth on the anterior side, so that the overall plan of dental restoration can be accurately established.

Second, a pair of base bite parts can be aligned and disposed at the same time in an accurate position on the posterior teeth side through the alignment extension part molded in the oral cavity, and the anterior side It does not interfere with the remaining teeth, so the precision of vertical dimension measurement can be remarkably improved.

Third, the partial bite guide is standardized and mass-produced in response to the average value representing the size of the arch by age and gender, but the thickness of the base bite part is formed smaller than the average height of the actual posterior teeth, so the occlusal base is pressed to an accurate vertical diameter Since the correction interval that can be corrected is secured, the vertical dimension of various patients can be accurately measured.

Fourth, the vertical spacing of the relief end extending along the lingual and labial edges of the seating surface is formed to be less than the standard gum ridge thickness so that the molded area with the oral cavity is increased, so pain and pain due to soft tissue compression when measuring the vertical dimension by occlusion in the oral cavity Discomfort can be minimized.

Referring to FIGS. 1A to 4, the vertical dimension measuring general-purpose partial bite guides 10A, 10B, 20A, and 20B according to a preferred embodiment of the present invention are the parts of the target arch where teeth on the posterior teeth are lost, which are the arches requiring dental restoration. It is for measuring the vertical dimension (VD) of an edentulous patient, and includes a base bite portion 11 and 21 and an alignment extension portion 15 and 25.

In detail, the base bite portions 11 and 21 are extended in correspondence with the predetermined molar-side standard teeth line (m), and are concavely recessed so as to surround the molar-side gum ridges (Ug, Lg) of the target arch on the inner surface It is preferable that the seating surfaces 12 and 22 are formed. At this time, the molar-side standard teeth line (m) is preferably understood as an arbitrary line connecting the standard teeth of premolars and molars in a dental arch model or virtual model corresponding to the anatomical average value.

And, it is preferable to understand that the gum ridges (Ug, Lg) are protruding structures in which teeth are embedded in the maxilla and mandible. In detail, the gum ridges (Ug, Lg) have an anatomical structure in which gum, which is a soft tissue, is wrapped around the surface of the alveolar bone protruding in an arc shape corresponding to the dental arch.

On the other hand, it is preferable that the mating base 30 is stacked on the upper surface of the pair of the base bite parts 11 and 21. At this time, the occlusal base 30 is provided to support a gap between an occlusal object of an opposing arch that occludes with the target arch and an outer surface of each of the base bite portions 11 and 21 . Here, the occlusal base 30 is preferably made of a material whose thickness can be adjusted corresponding to the depth of the occlusal scar formed by pressing and deforming by the occlusal pressure so as to be corrected to a thickness corresponding to the vertical dimension VD. . In this case, the occlusal mark is preferably understood as a mark formed corresponding to the end shape of the object to be occlusal while the outer surface of the occlusal base 30 is pressed by the occlusal pressure.

Here, when there are residual teeth such as natural teeth or artificial teeth in the opposing arch, it is preferable to understand that the occlusion object is the residual teeth and the bite marks are the chewing marks of the residual teeth. Alternatively, when the opposing arch is also edentulous, the object to be occluded is a partial bite guide (10A, 10B, 20A, 20B) provided in the opposing arch, and the bite marks are partial bite guides (10A, 10B, 20A, 20B) is preferably understood as a mark corresponding to the outer surface of each of the base bite portions 11 and 21.

Moreover, when the tooth support portions 18 and 28, which will be described later, are formed on the outer surfaces of the base bite portions 11 and 21, the bite marks correspond to the chewing surfaces 18a and 28a of the tooth support portions 18 and 28. It can be formed into marks that do. On the other hand, in the embodiment, the bite marks 31 and 32 are provided on the upper and lower jaws, respectively, of the tooth support portions 18 and 28 formed on each of the base bite portions 11 and 21 of the partial bite guides 10B and 20B. It is described and illustrated with marks corresponding to the outer surface.

In detail, the occlusal base 30 is pressurized and deformed by the occlusal pressure in correspondence to the end shape of the occlusal object of the opposing arch and the vertical diameter VD to form occlusal marks 31 and 32 while supporting a predetermined pressure. It may be provided with a solid wax that can be used. Alternatively, the occlusal base 30 may be made of a curable material such as putty, alginate, or resin, which is commonly used when taking impressions in dentistry.

At this time, it is preferable that the base bite parts 11 and 21 are provided as a pair to correspond to the outer surfaces of the gum ridges Ug and Lg of both posterior teeth. In addition, the base bite portions 11 and 21 are formed to have a predetermined thickness w1, and more preferably may be formed to have a thickness w1 less than a predetermined average molar height.

In addition, the thickness sum of the bite base 30 and the base bite parts 11 and 21 exceeds a preset standard vertical diameter so as to support the gap between the bite object and the outer surfaces of the bite base 30 and the base bite parts 11 and 21. It is desirable to form Here, in the present invention, the standard vertical diameter is preferably understood as a standard separation distance between the gum ridge (Lg) and the predetermined occlusal plane (op), and generally has a dimension of 6 to 9 mm. Accordingly, the maximum thickness between the seating surfaces 12 and 22 and the tooth support portions 18 and 28 may be set to 4 mm or less.

Here, when the outer surfaces of the base bite parts 11 and 21 are formed to be smooth, the thickness of the base bite parts 11 and 21 is a dimension corresponding to the vertical distance between the inner and outer surfaces of the base bite parts 11 and 21. It is desirable to understand that Alternatively, when the tooth support portions 18 and 28 are formed on the outer surfaces of the base bite portions 11 and 21, the thickness w1 of the base bite portions 11 and 21 is formed from the seating surfaces 12 and 22. It is preferable to understand that it is a dimension corresponding to the vertical distance between the outer surfaces of the toothed support portions 18 and 28. Hereinafter, the thickness w1 of the base bite portions 11 and 21 will be described and illustrated as being a dimension corresponding to the vertical distance between the outer surfaces of the toothed support portions 18 and 28 from the seating surfaces 12 and 22. .

Meanwhile, it is preferable that the alignment extension parts 15 and 25 are integrally formed to connect the pair of the base bite parts 11 and 21 . That is, a pair of the base bite parts 11 and 21 are integrally formed at both ends of the alignment extension parts 15 and 25, and through this, both posterior teeth of the oral cavity disconnected by the anterior teeth remaining teeth FtU and FtL. A pair of the base bite parts 11 and 21 may be aligned and arranged at the same time maintaining a constant interval.

Here, it is preferable that the alignment extension parts 15 and 25 are integrally formed by interconnecting the snow surface sides of the pair of the base bite parts 11 and 21 . Therefore, an anterior exposure space (e) in which the remaining teeth (FtU, FtL) on the anterior side of the target arch can be exposed can be formed between the front ends of the pair of base bite portions 11 and 21 . Accordingly, interference between the partial bite guides 10A, 10B, 20A, and 20B and the anterior residual teeth FtU and FtL can be prevented when the vertical dimension VD is measured. Through this, it is possible to accurately measure the vertical dimension (VD) of a partially edentulous patient whose molar side is edentulous by using the partial bite guides 10A, 10B, 20A, and 20B.

Further, it is preferable that molded surfaces 16 and 26 are formed on inner surfaces of the alignment extension parts 15 and 25 to surround the surfaces of the gum ridges Ug and Lg and adjacent tissues. Here, the surrounding tissue adjacent to the gum ridges (Ug, Lg) is preferably understood as a part corresponding to the upper hard palate or the lingual surface of the gum ridges (Ug, Lg).

At this time, the partial bite guides 10A, 10B, 20A, and 20B are manufactured by integrally 3-dimensionally printing the base bite portions 11 and 21 and the alignment extension portions 15 and 25 of a synthetic resin material having rigidity. this is preferable The partial bite guides 10A, 10B, 20A, and 20B are preferably made of a material capable of 3D printing and having a predetermined rigidity so as not to be excessively deformed by external force after curing. For example, oligomer acrylic resin, etc. It can be made of the same synthetic resin material.

In addition, it is preferable that the partial bite guides 10A, 10B, 20A, and 20B are manufactured in stages corresponding to an average value that can represent the size of the arch for each connection and gender. That is, the partial bite guides 10A, 10B, 20A, and 20B may be prepared as ready-made products that are standardized as large/medium/small.

Therefore, unlike the prior art in which the manufacturing cost and manufacturing period increased due to individually custom-made splints or bites for measuring the patient's vertical dimension according to each patient, the partial bite guides 10A, 10B, 20A, As 20B) is used, the overall cost of dental restoration is reduced, and the period required for manufacturing a dental restoration and placing a dental restoration implant (hereinafter referred to as a fixture) can be significantly shortened.

Moreover, the partial bite guides 10A, 10B, 20A, and 20B are prepared as ready-made products, but are mass-produced in a standard that can be universally applied to the oral cavity of various patients or an impression model corresponding thereto. Therefore, in a state where the partial bite guides 10A, 10B, 20A, 20B are prepared in advance according to the standard at the operator's side, such as a dentist, they can be applied immediately upon a patient's visit and corrected to correspond to the vertical dimension of the patient. .

Through this, the number of patient visits to the hospital can be substantially minimized to once in the process of acquiring scanning images and CT images, which is a step of acquiring information on the target arch and the opposing arch before the fixture is placed. That is, when a patient visits the hospital, an accurate vertical dimension can be measured using the partial bite guides 10A, 10B, 20A, and 20B. In addition, as soon as the partial bite guides 10A, 10B, 20A, and 20B are corrected and prepared to correspond to the vertical height VD, the scanning image including the information of the target arch and the opposing arch and the CT image can be obtained immediately. Moreover, since the point of time at which the plurality of scanning images and the CT image are acquired is substantially the same, the matching degree of each image is remarkably improved, and the overall plan of dental restoration can be precisely set based on this.

On the other hand, the seating surfaces 12 and 22 and the mold surfaces 16 and 26 are respectively connected to the surface of the gum ridges Ug and Lg on the molar side of the target arch and the gum ridges Ug and Lg by the occlusion pressure. It is preferable to correct pressure so as to conform to the surface of the adjacent tissue. To this end, it is preferable that the curable resin (r) is filled into the seating surfaces 12 and 22 and the molding surfaces 16 and 26 and then pressed by the occlusal pressure to be molded into the oral cavity.

That is, even if the partial bite guides 10A, 10B, 20A, and 20B are pre-manufactured and provided for general purposes, the seating surfaces 12 and 22 and the mold surfaces 16 and 26, which are inner surfaces thereof, are formed of the curable resin (r) It can be pressure-corrected so as to be substantially molded in the oral cavity through. Therefore, the seating surfaces 12 and 22 and the molding surfaces 16 and 26 corrected to correspond to the oral cavity may be corrected and formed to substantially mold to the oral cavity after curing.

Accordingly, as the seating surfaces 12 and 22 and the molding surfaces 16 and 26 are molded to the oral cavity, even if the partial bite guides 10A, 10B, 20A, and 20B are separated from the oral cavity and then remounted, a pair of The positions of the base bite parts 11 and 21 may be precisely aligned so as to always face the object to be occluded. Therefore, since the partial bite guides 10A, 10B, 20A, and 20B are provided as ready-made products and are calibrated to be individually molded to each patient, precision in measuring the vertical diameter can be remarkably improved.

At this time, it is preferable that the margin ends 13 and 23 extend downwardly from the buccal and lingual rims of the seating surfaces 12 and 22 . Through this, the area covered by the gum ridges (Ug, Lg) increases, and since the area directly molded to the oral cavity is widened, the alignment accuracy can be remarkably improved.

Here, it is preferable that the vertical distance w2 at which the margin ends 13 and 23 are extended is set to less than the predetermined standard gum ridge thickness. Through this, even if the occlusal pressure is applied so that the partial bite guides 10A, 10B, 20A, and 20B are corrected, the oral soft tissue is pressed against the ends of the free ends 13 and 23 to prevent pain from occurring. .

In addition, it is preferable that a plurality of through holes 17 and 27 are formed in the alignment extension parts 15 and 25 and the margin ends 13 and 23 to discharge the curable resin (r) pressed by the occlusion pressure. do. Through this, the gap between the partial bite guides 10A, 10B, 20A, 20B and the actual oral cavity is filled so that the seating surfaces 12 and 22 and the molding surfaces 16 and 26 are molded with the oral cavity surface, and the remaining Excess of the curable resin (r) may be discharged to the outside through the through-holes 17 and 27 . Therefore, since the inner surfaces of the partial bite guides 10A, 10B, 20A, and 20B are precisely lined, the accuracy of molding with the oral cavity can be remarkably improved.

In addition, since the molded area between the oral cavity and the partial bite guides 10A, 10B, 20A, and 20B is increased through the spare ends 13 and 23, the mounted state in the correct position can be stably maintained.

On the other hand, the teeth support portion 18 including chewing surfaces 18a and 28a and interdental correspondence portions 18b and 28b corresponding to the standard outer shape of posterior teeth on the upper surface of the base bite portion 11 and 21 is further It is desirable to form That is, as shown in FIGS. 1A and 2A, the partial bite guides 10A and 20A may have the base bite portions 11 and 21 formed on a smooth surface, or the partial bite guides as shown in FIGS. 1B and 2B. (10B, 20B) may be provided in the form of the tooth support portion 18 is formed on the outer surface of the base bite portion (11, 21).

In addition, when the target arch is the maxilla, as shown in FIGS. 1A and 1B, the alignment extension part 15 of the partial bite guides 10A and 10B may be formed to correspond to the rear surface of the hard palate adjacent to the posterior teeth. there is. Alternatively, when the target arch is the lower jaw, as shown in FIGS. 2A to 2B, the partial bite guides 20A and 20B are arranged in the central part of the alignment extension parts 15 and 25 so that the tongue movement part is opened to the lingual side. It may be formed round to correspond to the lingual surface of the gum ridge (Lg) adjacent to the side.

As such, the partial bite guides 10A, 10B, 20A, and 20B can be selected in one of large/medium/small sizes according to the patient's oral environment, and include or do not include the tooth support portions 18 and 28. It is possible to choose a form that does not. In addition, when both the posterior teeth of the upper and lower jaws are edentulous, at least one side of the upper and lower jaws is equipped with the partial bite guides 10B and 20B including the tooth support portions 18 and 28, and the other side is equipped with the tooth support portions 18 and 28 The partial bite guides 10A and 20A that do not include may be mounted.

In addition, the partial bite guides 10A, 10B, 20A, and 20B may be used by purchasing pre-manufactured and mass-produced commercial products from the operator, and when the operator has a 3D printer and a curing machine, the partial bite guides 10A, 10B, 20A, 20B), a design model suitable for the patient can be selected and 3D printed. That is, the partial bite guides 10A, 10B, 20A, and 20B are actually output and manufactured products or design model information for the partial bite guides 10A, 10B, 20A, and 20B are supplied to the operator or manufacturer. It can be.

Furthermore, referring to FIGS. 3 and 4 , the partial bite guides 10B and 20B coated with the curable resin r on the inner surfaces of the seating surfaces 12 and 22 and the mold surfaces 16 and 26 It is disposed on the upper and lower molar side gum ridges (Ug, Lg), respectively. At this time, the occlusal bases 30 are stacked between the facing outer surfaces of the tooth support portions 18, and the occlusal pressure exerts pressure on the inner and outer surfaces of the occlusal bases 30 and the outer surfaces of the tooth support portions 18 respectively. Pressure correction is performed so that the corresponding occlusal marks 31 and 32 are formed.

Here, the thickness w1 of each of the base bite portions 11 and 21 is formed to a thickness less than the preset average molar height, and the sum of the thicknesses of each of the base bite portions 11 and 21 and the occlusal base 30 is formed to exceed the standard vertical diameter. Accordingly, a marginal thickness is secured in the occlusion base 30 so that the occlusion base 30 is corrected to correspond to the vertical height, and at the same time, a marginal gap is secured between the upper and lower gaps of the base bite portions 11 and 21. It can be. Through this, even if the vertical diameter of the patient is smaller or larger than the standard vertical diameter, pressure correction can be accurately performed with respect to the vertical diameter of the patient.

That is, the base bite parts 11 and 21, in particular, support the posterior teeth of the oral cavity in place of the missing posterior teeth. Therefore, the bite pressure can be stably supported from the mesial side to the distal side of the oral cavity through the anterior residual teeth FtU and FtL and the partial bite guides 10B and 20B. Through this, it is possible to solve the conventional problem that it is difficult to accurately measure the vertical dimension due to excessive occlusion of the anterior residual teeth (FtU, FtL).

In addition, since the base bite portions 11 and 21, in particular, the tooth-shaped support portion 18 is formed smaller than the average height of the actual posterior teeth, the upper and lower spacing range in which the vertical diameter of the upper and lower jaws can be corrected for the occlusion pressure increases. That is, since the corrected interval between the upper and lower jaws is secured, precision in measuring the vertical diameter can be remarkably improved.

Furthermore, since the alignment extension parts 15 and 25 are formed to correspond to the lingual side of the oral cavity or the hard palate spaced apart from the anterior residual teeth FtU and FtL, the anterior teeth are interposed between the pair of base bite parts 11 and 21. The anterior exposure space (e) in which the side remaining teeth (FtU, FtL) can be exposed is formed. Through this, even if the partial bite guides 10B and 20B are mounted as they are in the oral cavity, interference with the anterior residual teeth FtU and FtL does not substantially occur, so that the occlusal base 30 has a precise vertical diameter corresponding to the correct vertical diameter. can be corrected accordingly.

At this time, the seating surfaces 12 and 22 and the molding surfaces 16 and 26 are corrected to precisely match the surface of the oral cavity through the curable resin r. Therefore, the vertical diameter can be accurately aligned and guided using the partial bite guides 10B and 20B. Moreover, as the free ends 13 and 23 extend to the lingual and labial sides of the seating surfaces 12 and 22, the contact mold area between the oral cavity and the partial bite guides 10B and 20B increases. Therefore, since the partial bite guides 10B and 20B can be mounted at substantially the same position even if they are repeatedly remounted after being separated from the oral cavity, accuracy and precision can be remarkably improved.

Moreover, the base bite parts 11 and 21 and the alignment extension parts 15 and 25 integrally formed therewith are formed of a material having rigidity by being three-dimensionally printed and hardened. Therefore, since the upper and lower jaws are not arbitrarily deformed by the occlusion pressure, the vertical diameter VD can be accurately measured. In addition, since the position where the base bite parts 11 and 21 are mounted on both posterior teeth is firmly maintained through the alignment extension parts 15 and 25, the accuracy of the measured vertical diameter (VD) can be further improved. there is.

Occlusal, the thickness of which is adjusted based on the depth of the occlusal scar formed by pressing and deforming in response to the outer end of the occlusal object on the side of the opposing arch, which is extended in response to the predetermined molar-side standard dental alignment line and occluded with the target arch by occlusal pressure A pair of base bites having a base laminated on the outer surface and a seating surface formed on the inner surface that is concavely recessed to surround the posterior gum ridge of the target arch and pressurized and corrected to match the posterior gum ridge surface in response to occlusal pressure wealth; and
The pair of base bite parts, which are cut off by the remaining teeth on the anterior side of the target arch, maintain a constant interval and are arranged simultaneously on both posterior teeth to form an exposure space where the remaining teeth on the anterior side are exposed. The tongue surface side is integrally formed by interconnecting, but the surface of the surrounding tissue adjacent to the gum ridge on the inner surface to align the position of the pair of the base bite parts so that each of the base bite parts on which the occlusal base is stacked faces the bite object A molded surface that is pressed and corrected to be molded is formed and includes an alignment extension part integrally formed with the base bite part and a synthetic resin material having rigidity with the base bite part,
The base bite portion is formed to a thickness less than a predetermined average molar height so as to secure a correction interval between the upper and lower jaw, and the thickness of the bite base and the base bite portion is the sum of the thicknesses to support the gap between the bite object and the outer surface of the base bite portion. A universal partial bite guide for measuring vertical diameter, characterized in that it is formed to exceed the predetermined standard vertical diameter. delete According to claim 1,
The vertical dimension measuring universal partial bite guide, characterized in that the free end extends downward from the buccal and lingual edges of the seating surface, and the vertical interval at which the free end extends is set to less than a predetermined standard gum ridge thickness. According to claim 3,
The seating surface and the mold surface are formed to have a continuous surface contour corresponding to a predetermined standard oral surface, and a curable resin is filled therein and pressed by the occlusal pressure to mold and match the oral cavity.
A universal partial bite guide for measuring vertical diameter, characterized in that a plurality of through-holes are formed in the alignment extension part and the margin end to discharge the curable resin pressed by the occlusal pressure. According to claim 1,
On the upper surface of the base bite portion, a tooth support portion including a chewing surface and an interdental correspondence corresponding to the standard appearance of the molar side teeth is further formed,
The alignment extension part is formed to correspond to the rear surface of the hard palate adjacent to the molar side when the target arch is the upper jaw, and when the target arch is the lower jaw, the gum adjacent to the root side of the anterior tooth of the lower jaw is formed so that the tongue moving part is formed in the central part to the lingual side. A universal partial bite guide for measuring vertical diameter, characterized in that it is formed round to correspond to the lingual surface of the ridge.
