Description

Universal partial bite guide for measuring occlusal vertical dimension

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

In general, a dental restoration refers to an artificial periodontal tissue in the oral cavity that replaces a missing tooth and artificially restores the appearance and function.

In detail, when natural teeth are left in a lost state, distortion of the teeth occurs in adjacent teeth and opposing teeth of the missing teeth, resulting in deformation of the facial shape, and lowering of the masticatory function, thereby aggravating inconvenience in daily life. Moreover, when the state of loss of natural teeth is prolonged, the alveolar bone surrounding the lost teeth 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 masticatory function, and to prevent deformation or damage to the remaining teeth on the arch side of the opposing tooth or the target arch that requires a dental restoration. Here, the dental restoration may be provided as an artificial crown that is individually matched to the lost tooth, or may be provided in the form of a prosthesis to replace a plurality of or all missing teeth on the target arch side. These dental restorations are made of titanium, etc. that does not have a rejection reaction in the human body to replace the lost root, and are fixed in the oral cavity through an implant (fixture) to be placed on the alveolar bone.

On the other hand, in order to properly design the dental restoration for each patient and install it in an accurate position, accurate and precise oral information is required. For this, internal tissue information such as surface information of the oral cavity and alveolar bone shape/bone density is required together. Therefore, an image registration process is required to acquire scan images and CT images corresponding to the patient's upper and lower jaws, and to align and form them corresponding to the vertical height.

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

However, when only the anterior portion partially remains, there is a problem in that the upper and lower incisors are excessively engaged according to the anatomical dental structure. For this reason, the patient's accurate vertical diameter cannot be calculated, and the height of the finally manufactured dental restoration is set lower than the vertical diameter suitable for the patient.

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

However, this conventional bite means is substantially provided in an arc shape corresponding to the overall dental arch shape, and thus is formed to have a predetermined thickness as a whole. For this reason, it can be easily utilized when actually calculating the vertical diameter of an edentulous patient, but in the case of a partially edentulous jaw, interference occurs due to the thickness of the bite means between the remaining teeth and the opposing teeth. Therefore, in the case of a partially edentulous jaw, there is an inconvenience in that the 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 the bite means is difficult to be fixed in the oral cavity. Due to this, when the patient opens or moves the mouth in a state in which the bite means is in its mouth, there is a problem in that it is difficult to calculate the correct vertical height while the position of the bite means is moved/departed.

Moreover, in the case of the conventional custom splint, because it is individually designed for each patient, the design process and cost increase, and there is a problem in that the economic efficiency is lowered due to the increase in the overall cost and period of dental restoration.

In order to solve the above problems, the present invention aims to provide a general-purpose partial bite guide for measuring vertical height with improved usability.

In order to solve the above problems, the present invention provides a bite guide for measuring the vertical height of a partially edentulous patient who has lost posterior teeth of a target arch, extending corresponding to a preset posterior standard dentition line, and depending on occlusal pressure An occlusal base whose thickness is adjusted based on the depth of the occlusal scar formed by pressing and deforming corresponding to the outer end of the occlusal object on the side of the occlusal arch that is occluded with the target arch is stacked on the outer surface and provided on the inner surface of the posterior side of the target arch Doedoe concave to surround the gum ridge, a pair of base bite portions formed with a seating surface that is pressurized to match the posterior gum ridge surface in response to occlusal pressure; and the lingual side of the pair of base bite portions are interconnected to expose the remaining teeth on the anterior side of the target arch between the front ends of the pair of base bite portions, and each of the base bite portions on which the occlusal base is stacked is formed in the occlusion In order to align the position of the pair of base bite portions to face the object, the vertical height measurement general-purpose partial bite guide comprising an alignment extension formed with a mating surface that is pressurized and corrected to fit on the surface of the surrounding tissue adjacent to the gum ridge on the inner surface. do.

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

First, as the base bite part is provided to support the posterior spacing of the patient with tooth loss, it is possible to accurately measure the vertical diameter by preventing excessive occlusion of the remaining anterior teeth, so the overall plan of dental restoration can be established accurately.

Second, a pair of base bite parts can be aligned and arranged at the correct position on the posterior side at the same time through the alignment extension supported in the oral cavity. Since it does not interfere with the remaining teeth, the precision of vertical diameter measurement can be significantly improved.

Third, partial bite guides are 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 molars, so the occlusal base is pressed to the correct vertical height Since the calibration interval that can be corrected is secured, it is possible to accurately measure the vertical height of various patients.

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

At this time, in FIGS. 3 to 4, a tooth support part to be described later is formed in a base bite part to be described later as an example in a state in which both upper and lower molars are lost.

1A to 4 , the general-purpose partial bite guides 10A, 10B, 20A, and 20B for measuring vertical height according to a preferred embodiment of the present invention are the part in which the posterior teeth of the target arch, which is the arch that requires dental restoration, are lost. For measuring the vertical diameter (VD) of an edentulous patient, it includes base bite parts 11 and 21 and alignment extension parts 15 and 25 .

In detail, the base bite portions 11 and 21 extend corresponding to the preset posterior standard dentition line (m), and are concavely recessed to surround the posterior gum ridges (Ug, Lg) of the target arch on the inner surface. It is preferable that the seating surfaces 12 and 22 are formed. In this case, the posterior standard dentition line (m) is preferably understood as an arbitrary line connecting the standard dentitions of premolars and molars in a dental arch model or virtual model corresponding to anatomical average values.

In addition, the gum ridges (Ug, Lg) are preferably understood as a protruding structure in which teeth are embedded in the maxilla and the mandible. In detail, the gum ridges (Ug, Lg) have an anatomical structure in which the gum, which is a soft tissue, is wrapped on 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 occlusal base 30 is laminated on the upper surfaces of the pair of base bite units 11 and 21 . In this case, the occlusal base 30 is provided to support a gap between the occlusal object of the occlusal arch and the occlusal arch and the outer surfaces of the base bite units 11 and 21 respectively. Here, it is preferable that the occlusal base 30 is made of a material whose thickness can be adjusted in response to the depth of the occlusal scar formed by being pressurized and deformed by the occlusal pressure to correct the thickness corresponding to the vertical diameter (VD). . At this time, the occlusal mark is preferably understood as a mark formed corresponding to the shape of the end of the occlusal object while the outer surface of the occlusal base 30 is pressed by the occlusal pressure.

Here, when residual teeth such as natural teeth or artificial teeth exist in the opposing arch, it is preferable to understand that the occlusion object is the remaining teeth and the occlusion marks are chewing marks of the remaining teeth. Alternatively, when the opposing arch is also edentulous, the occlusal object is a partial bite guide (10A, 10B, 20A, 20B) provided in the opposing arch, and the occlusal mark is a partial bite guide (10A, 10B) installed on the opposing side. It is preferable to understand that the marks correspond to the outer surfaces of the base bite portions 11 and 21 of each of 20A and 20B.

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

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

At this time, it is preferable that the base bite portions 11 and 21 are provided as a pair corresponding to the outer surfaces of the gum ridges (Ug, Lg) of both molars. 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.

And, to support the gap between the occlusal object and the outer surfaces of the base bite parts 11 and 21, the sum of the thicknesses of the occlusal base 30 and the base bite parts 11 and 21 exceeds a preset standard vertical diameter. It is preferable to form Here, it is preferable to understand that the standard vertical diameter in the present invention is the standard spacing between the gum ridge (Lg) and the preset 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 surface of the base bite part (11, 21) is formed to be slippery, the thickness of the base bite part (11, 21) is a dimension corresponding to the vertical distance between the inner and outer surfaces of the base bite part (11, 21) It is preferable 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 obtained from the seating surfaces 12 and 22 . It is preferable to understand that the dimension corresponds to the vertical distance between the outer surfaces of the tooth support portions 18 and 28 . Hereinafter, the thickness w1 of the base bite portions 11 and 21 is described and illustrated as a dimension corresponding to the vertical distance between the outer surfaces of the tooth support portions 18 and 28 from the seating surfaces 12 and 22 . .

On the other hand, it is preferable that the alignment extension parts 15 and 25 are integrally formed to connect the pair of base bite parts 11 and 21 . That is, a pair of the base bite portions 11 and 21 are integrally formed at both ends of the alignment extension portions 15 and 25, and both molars of the oral cavity are cut by the anterior residual teeth (FtU, FtL) through this. A pair of the base byte portions 11 and 21 may be arranged at the same time by maintaining a constant interval therebetween.

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

In addition, it is preferable that the inner surfaces of the alignment extensions 15 and 25 have molded surfaces 16 and 26 that surround the surface of the surrounding tissues adjacent to the gum ridges Ug and Lg. Here, it is preferable to understand that the surrounding tissue adjacent to the gum ridges (Ug, Lg) is a portion corresponding to the hard palate of the maxilla or the lingual surface of the gum ridges (Ug, Lg).

At this time, the partial bite guides (10A, 10B, 20A, 20B) are three-dimensionally printed integrally with the base bite parts 11 and 21 and the alignment extension parts 15 and 25 with a synthetic resin material having rigidity and are manufactured. 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 an external force after curing, for example, an oligomeric acrylic resin, etc. It may 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 by being divided into stages corresponding to an average value that can represent the size of each connection and gender. That is, the partial bite guides 10A, 10B, 20A, and 20B may be prepared as ready-made products standardized in large/medium/small.

Therefore, unlike the prior art in which the manufacturing cost and manufacturing period increased due to individual ordering of splints or bites for measuring the patient's vertical diameter, the partial bite guides (10A, 10B, 20A, 10A, 10B, 20A, 20B), the overall cost of dental restoration is reduced, and the period required for dental restoration manufacturing and placement of dental restorations (hereinafter referred to as fixtures) can be significantly shortened.

Moreover, the partial bite guides (10A, 10B, 20A, 20B) are prepared as ready-made products and 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, the dental operator can use the partial bite guides (10A, 10B, 20A, 20B) in advance according to the standard and immediately apply it when a patient visits the patient, correcting it to correspond to the patient's vertical height. .

Through this, the number of visits to the patient can be substantially minimized to one in the process of acquiring the scanning image and the CT image, which is the step of acquiring information on the target arch and the antagonistic arch before the fixture is placed. That is, the correct vertical height can be measured using the partial bite guides 10A, 10B, 20A, and 20B when the patient visits the hospital. In addition, as soon as the partial bite guides 10A, 10B, 20A, and 20B are corrected to correspond to the vertical height (VD) and prepared, the scanning image and the CT image including information on the target arch and the opposing arch are obtained. can be obtained immediately. Moreover, since the acquisition time of the plurality of the scanning images and the CT image is substantially the same, the degree of matching of each image is significantly 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 mating surfaces 16 and 26 are formed with the posterior side gum ridge (Ug, Lg) surface and the gum ridge (Ug, Lg) of the target arch, respectively, by the occlusal pressure. It is preferable to pressurize it so that it conforms to the surface of the adjacent tissue. To this end, it is preferable that a curable resin (r) is filled in the seating surfaces 12 and 22 and the mating surfaces 16 and 26 and is pressed by the occlusal pressure to re-line to fit into the oral cavity.

That is, even if the partial bite guides 10A, 10B, 20A, 20B are prepared and provided for general purpose, the inner surfaces of the seating surfaces 12 and 22 and the mating surfaces 16 and 26 are the curable resin (r) The pressure can be corrected to substantially conform to the oral cavity. Accordingly, the seating surfaces 12 and 22 and the mating surfaces 16 and 26 corrected to correspond to the oral cavity may be corrected and formed to substantially fit into the oral cavity after curing.

Accordingly, as the seating surfaces 12 and 22 and the mating surfaces 16 and 26 fit into the oral cavity, even if the partial bite guides 10A, 10B, 20A, 20B are separated from the oral cavity and then remounted, a pair of The positions of the base bite units 11 and 21 may be precisely aligned so that they always face the occlusal object. Accordingly, since the partial bite guides 10A, 10B, 20A, and 20B are provided as ready-made products and are calibrated to be individually fitted to each patient, precision when measuring vertical height can be significantly improved.

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

Here, it is preferable that the vertical interval w2 in which the margin ends 13 and 23 are extended is set to less than a preset standard gum ridge thickness. Through this, even when the occlusal pressure is applied so that the partial bite guides 10A, 10B, 20A, and 20B are corrected, the oral soft tissue is pressed to the ends of the spare ends 13 and 23, thereby preventing 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 spare ends 13 and 23 so that the curable resin r pressed by the occlusal pressure is discharged. do. Through this, the seating surfaces 12 and 22 and the mating surfaces 16 and 26 are filled in the gap between the partial bite guides 10A, 10B, 20A, 20B and the actual oral cavity so that they are mated with the oral cavity surface. An excess of the curable resin r may be discharged to the outside through the through holes 17 and 27 . Accordingly, since the inner surfaces of the partial bite guides 10A, 10B, 20A, and 20B are precisely re-lined, the accuracy of matching with the oral cavity can be significantly improved.

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

On the other hand, the tooth support portion 18 comprising the masticatory surfaces 18a, 28a and interdental correspondence portions 18b, 28b corresponding to the standard shape of the posterior teeth on the upper surface of the base bite portions 11 and 21 is further It is preferable to form That is, as shown in Figs. 1a and 2a, the partial bite guides 10A and 20A may be formed of a smooth surface of the base bite portions 11 and 21, or, as shown in Figs. 1b and 2b, the partial bite guides (10B, 20B) may be provided in a form in which 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 partial bite guides 10A and 10B may be formed such that the alignment extension 15 corresponds to the posterior surface of the hard palate adjacent to the molar side. have. Alternatively, when the target arch is the mandible, as shown in FIGS. 2A to 2B , the partial bite guides 20A and 20B are located at the center of the alignment extensions 15 and 25 so that the tongue flow part opens lingually to the lingual root of the anterior part of the mandible. It may be formed to be rounded to correspond to the lingual surface of the gum ridge (Lg) adjacent to the side.

As such, the partial bite guides (10A, 10B, 20A, 20B) can be selected in one of large/medium/small sizes according to the oral environment of the patient, and the tooth support parts 18 and 28 are included or not included. It can be selected in non-existent form. In addition, when both the upper and lower molars are edentulous, at least one of the upper and lower jaws is equipped with the partial bite guides (10B, 20B) including the tooth support parts (18, 28), and the other side is the tooth support part (18, 28). The partial bite guides 10A and 20A that do not include may be mounted.

In addition, the partial bite guides (10A, 10B, 20A, 20B) can be purchased from the operator's side by purchasing a commercially manufactured and mass-produced product, and when the operator's side has a 3D printer and a curing machine, the partial bite guide (10A, Among the design models of 10B, 20A, 20B), a design model suitable for the patient can be selected and used after 3D printing. That is, the partial bite guides (10A, 10B, 20A, 20B) are supplied to the operator or the manufacturer as design model information for the actually printed and manufactured product or the partial bite guides (10A, 10B, 20A, 20B). can be

Furthermore, referring to FIGS. 3 to 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 mating surfaces 16 and 26 are It is placed on the posterior gum ridges (Ug, Lg) of the maxilla and mandible, respectively. At this time, the occlusal base 30 is laminated between the opposite outer surfaces of each of the tooth support parts 18, and the inner and outer surfaces of the occlusal base 30 by the occlusal pressure on the outer surface of each tooth support part 18. The pressure is corrected 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 have a thickness less than a 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 It is formed to exceed the standard vertical diameter. Accordingly, an extra thickness is secured on the occlusal base 30 so that the occlusal base 30 is corrected to correspond to the vertical height, and at the same time, an extra gap between the upper and lower gaps of the base bite parts 11 and 21 is secured. can be Through this, even if the vertical diameter of the patient is smaller or larger than the standard vertical diameter, the pressure correction can be accurately performed with respect to the vertical diameter of the patient.

That is, the base bite portions 11 and 21, in particular, the tooth support portion 18 supports the molar side of the oral cavity in place of the missing molars. Accordingly, the occlusal pressure can be stably supported from the mesial side to the distal side of the oral cavity through the anterior residual teeth (FtU, FtL) and the partial bite guides (10B, 20B). Through this, it is possible to solve the conventional problem that it is difficult to accurately measure the vertical height due to excessive occlusion of the anterior residual teeth (FtU, FtL).

In addition, since the base bite portions 11 and 21, particularly the tooth support portion 18, are formed to be smaller than the average height of the actual molars, the vertical distance range in which the vertical height of the upper and lower jaws can be corrected with respect to the occlusal pressure increases. That is, by securing the correction interval between the upper and lower jaws, the precision when measuring the vertical height can be significantly improved.

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

At this time, the seating surfaces 12 and 22 and the mating surfaces 16 and 26 are corrected to precisely fit the surface of the oral cavity through the curable resin (r). Accordingly, the vertical height and diameter can be precisely aligned and guided using the partial bite guides 10B and 20B. Moreover, as the spare ends 13 and 23 extend on the lingual and labial sides of the seating surfaces 12 and 22, the contact area between the oral cavity and the partial bite guides 10B and 20B increases. Therefore, even if the partial bite guides (10B, 20B) are repeatedly remounted after separation from the oral cavity, they can be mounted in substantially the same position, so that accuracy and precision can be significantly improved.

Furthermore, the base bite portions 11 and 21 and the alignment extension portions 15 and 25 formed integrally therewith are 3D printed and cured to form a material having rigidity. Therefore, the vertical diameter (VD) can be precisely measured because it is not arbitrarily deformed by the occlusal pressure between the upper and lower jaws. In addition, since the position where the base bite parts 11 and 21 are mounted on both molars is firmly maintained through the alignment extension parts 15 and 25, the accuracy of the measured vertical diameter (VD) can be further improved. have.
