Description

Technical Field

[0001] The present application relates to the field of oral appliances, and in particular to a tool for shaping the gums of adjacent teeth before crown restoration. Background Art

[0002] When a tooth is missing, an artificial implant is needed at the missing site. The implant will be placed in the alveolar bone at the missing site. The crown can only be installed after the alveolar bone and implant have completed bone fusion. This bone fusion period usually takes 3-6 months.

[0003] During this period of bone fusion, the adjacent teeth to the missing position will tilt toward the missing position.

[0004] The main reason for the tilting of adjacent teeth is that after tooth loss, the balance of the missing tooth area is destroyed. Without the support of the teeth on the other side, the adjacent teeth are prone to tilt toward the missing area. After tooth loss, the alveolar bone may be absorbed, making the gap in the missing area smaller, further affecting the position of the adjacent teeth. The remaining teeth may move to compensate for the missing teeth and change the normal occlusion relationship, which may also cause the adjacent teeth to tilt.

[0005] Therefore, in order to reduce the inclination of the adjacent teeth in the missing position, a tool for shaping the gingiva of the adjacent teeth before implant crown restoration was designed. Summary of the invention

[0034] The following is combined with Figure 1 -Attached Figure 4 , further details of this application are given.

[0035] The embodiment of the present application discloses a tool for shaping the gingiva of adjacent teeth before implant crown restoration.

[0036] A joint tool for shaping the gingiva of adjacent teeth before crown restoration. When a tooth needs to be implanted, a gingival implant 1 needs to be implanted in advance at the missing position. The crown can be installed only after the gingival implant 1 is integrated with the alveolar bone. The application is used to shape the gingiva of the adjacent teeth at the missing position during the time when the alveolar bone is integrated with the implant bone to prevent the adjacent teeth from shifting or tilting during this period.

[0037] Reference Figure 1 and Figure 2 As shown, it includes a base structure 2, a vertical adaptation structure 3, a support member 4, an adjacent tooth adaptation structure 5 and an adjacent tooth repositioning structure 6; the base structure 2 is connected to the gingival implant 1, and the base structure 2 is used to provide a stable support. The connection method between the base structure 2 and the gingival implant 1 can be a screw connection. The gingival implant 1 is provided with a thread groove, and the base structure 2 is provided with an external thread, which is screwed with the thread groove using the external thread.

[0038] The material and structure of the base structure 2 can be individually designed to meet the preset gingival contour of the patient, so as to better shape the gingival shape to fill the gap between the gingival papillae caused by the original tilting of the adjacent teeth.

[0039] The vertical adaptation structure 3 is slidably connected to the base structure 2 in the vertical direction and is fixed with a first locking portion 31. The vertical adaptation structure 3 can be raised and lowered along the base structure 2. Its main function is to be able to adjust and adapt to the tooth height of different patients. After the vertical adaptation structure 3 is raised and lowered along the base structure 2, the patient's tooth height is determined, and the first locking portion 31 is used to fix the vertical structure to the base structure 2 to facilitate the adaptation of the patient's tooth height.

[0040] The support member 4 is installed on one end of the vertical adaptation structure 3 away from the base structure 2. The support member 4 is laterally arranged on the vertical adaptation structure 3 along the direction from outside the oral cavity to inside the oral cavity to provide installation for other components. The support member 4 can adopt a support frame.

[0041] The adjacent tooth adaptation structure 5 is slidably connected to the support member 4 in the extension direction. The adjacent tooth adaptation structure 5 can slide along the support member 4 to adjust its position. The adjacent tooth adaptation structure 5 is mainly used to correct and restore the original adjacent area of ​​the adjacent teeth to prevent the adjacent teeth from twisting due to the influence of force, resulting in position displacement.

[0042] The adjacent tooth adaptation structure 5 is fixed with a second locking portion 51. After the adjacent tooth adaptation structure 5 slides along the support member 4 to a position adapted to the adjacent tooth and abuts against the adjacent tooth, the adjacent tooth adaptation structure 5 is locked by the second locking portion 51, so that the adjacent tooth adaptation structure 5 is always pressed against the adjacent tooth, thereby preventing the adjacent tooth from twisting or shifting.

[0043] The adjacent tooth repositioning structure 6 is connected to the support member 4. After the original tooth at the missing position falls off, the adjacent tooth loses the support of the original tooth at the missing position and tilts toward the missing position. The adjacent tooth repositioning structure 6 is used to reposition the adjacent tooth. The adjacent tooth repositioning structure 6 presses against the adjacent tooth so that the adjacent tooth is supported and repositioned and returns to its original position. In cooperation with the adjacent tooth adaptation structure 5, the tilted adjacent tooth is moved to its original physiological position by squeezing and pushing during the bone integration time, and the adjacent tooth will not tilt toward the missing position.

[0044] Specifically, the base structure 2 is connected to the gingival implant 1, and the vertical adaptation structure 3 is used to move vertically along the base structure 2. After the position is adjusted, it is fixed by the first locking part 31 to adapt to the tooth height of different patients. The adjacent tooth adaptation structure 5 moves along the support 4 until it contacts the adjacent teeth. The position of the adjacent tooth adaptation structure 5 is fixed by the second locking part 51. The adjacent tooth adaptation structure 5 is against the adjacent teeth to prevent the adjacent teeth from twisting or shifting. Then, the adjacent tooth repositioning structure 6 provides a driving force to the adjacent teeth away from the missing position, so that the tilted adjacent teeth are repositioned and the original physiological position of the adjacent teeth is restored. After correction, the occlusal contact relationship of the adjacent teeth is restored, the original occlusal function of the adjacent teeth is restored, and the effect of combined orthodontics is provided.

[0045] For further reference, Figure 1 As shown, the abutment structure 2 includes a transgingival connection portion 21 and a working portion 22; the transgingival connection portion 21 is connected to the gingival implant 1, and the transgingival connection portion 21 can be the transgingival part of the personalized abutment. The structure conforms to the personalized designed gingival contour to adapt to the gingival shape and fill the gap caused by the original inclination of the adjacent teeth.

[0046] The working part 22 is fixedly mounted on the transgingival connection part 21 and extends away from the gingival implant 1. The working part 22 may be an upper working section of a personalized abutment, specifically a fixing rod or a fixing frame, which may provide insertion and support for the vertical adaptation structure 3 after extension.

[0047] Specifically, the transgingival connection part 21 is connected to the gingival implant 1 in the oral cavity. By personalizing the design of the site to meet the preset gingival contour, the gingival shape can be better shaped to fill the gap between the gingival papillae caused by the original tilt of the adjacent teeth. The transgingival connection part 21 provides support for the working part 22, and the vertical adaptation structure 3, the support member 4, the adjacent tooth adaptation structure 5 and the adjacent tooth reduction structure 6 can obtain a stable installation environment.

[0048] Further, refer to Figure 1 As shown, the vertical adaptation structure 3 also includes an adaptation sleeve 32, the inner diameter of the adaptation sleeve 32 matches the diameter of the working part 22, so that the adaptation sleeve 32 is plugged into the working part 22. After plugging, the adaptation sleeve 32 can be raised and lowered along the working part 22 to adjust the height to adapt to the tooth height of different patients.

[0049] A threaded hole is provided on the adapting sleeve 32, and the first locking portion 31 is screwed into the threaded hole and abuts against the working portion 22. After the adapting sleeve 32 is adapted to the patient's tooth height, the first locking portion 31 is inserted into the threaded hole. The first locking portion 31 can adopt a first bolt. After the first locking portion 31 is screwed into the threaded hole, it abuts against the working portion 22. As the first locking portion 31 is tightened, the adapting sleeve 32 cannot continue to move along the working portion 22, thereby achieving a locking effect.

[0050] Specifically, the adaptable sleeve 32 is moved up and down along the working part 22 to adjust the extension height of the adaptable sleeve 32 to adapt to the tooth height of different patients. After the adjustment is completed, the first locking part 31 is screwed into the threaded hole and tightened against the surface of the working part 22, so as to fix the installation height of the adaptable sleeve 32. When disassembly is required, the first locking part 31 can be screwed out of the threaded hole.

[0051] In some embodiments, reference Figure 1 As shown, the adjacent tooth adaptation structure 5 also includes a transverse joint portion 52 and an adaptation splint 53; the transverse joint portion 52 is sleeved on the support member 4 and slides along the support member 4. The position on the support member 4 can be adjusted during sliding, and the adaptation splint 53 is installed on the outer wall of the transverse joint portion 52. Therefore, the adaptation splint 53 adjusts its position on the support member 4 as the transverse joint portion 52 moves until the adaptation splint 53 abuts against the adjacent tooth. The transverse joint portion 52 can adopt a transverse sleeve.

[0052] The transverse joint portion 52 is provided with a threaded hole. When the adaptable splint 53 abuts against the adjacent tooth, the second locking portion 51 is screwed into the threaded hole. The second locking portion 51 can adopt a second bolt. The second locking portion 51 is continuously tightened and abuts against the support member 4, so that the transverse joint portion 52 can no longer move along the support member 4, thereby achieving the effect of fixing the transverse joint portion 52 and the adaptable splint 53.

[0053] After the adaptive splint 53 abuts against the adjacent tooth, the twisting track of the adjacent tooth is blocked by the adaptive splint 53, so that the adjacent tooth cannot twist or shift, thereby achieving the effect of correcting and preventing the adjacent tooth from shifting.

[0054] The surface of the adaptable splint 53 may be provided with a fitting groove that fits the curvature of the adjacent teeth, so as to ensure that when in contact with the adjacent teeth, the contact is more stable and the force is more balanced.

[0055] For further reference, Figure 1 As shown, the adaptation sleeve 32 is connected to the center point of the support member 4, dividing the support member 4 into two sections. The adjacent tooth adaptation structure 5 is provided with two groups, which are respectively arranged on the two sections of the support member 4, so that the side of the adjacent teeth facing outside the oral cavity and the side facing the throat can be fixed, and the adjacent teeth are clamped from two directions, thereby further increasing the tightness of the adjacent teeth, avoiding deviation or twisting, and improving the accuracy and stability of correction.

[0056] Further, refer to Figure 1As shown, both ends of the support member 4 are provided with a stop protrusion 41, and the transverse joint part 52 is provided with an anti-drop protrusion 54. When the transverse joint part 52 moves to any end of the support member 4, the anti-drop protrusion 54 is engaged with the stop protrusion 41. The stop protrusion 41 and the anti-drop protrusion 54 can prevent the transverse joint part 52 from being separated from the support member 4, thereby preventing the transverse joint part 52 from falling off and providing a stable transverse joint part 52.

[0057] In some embodiments, reference Figure 2 As shown, the adjacent tooth reduction structure 6 also includes a fixed tube 61 and an elastic portion 62; the fixed tube 61 is installed at the center of the support member 4, one end of the elastic portion 62 is connected to the fixed tube 61, and the other end is in contact with the adjacent tooth. When the elastic portion 62 provides pushing and reduction for the adjacent tooth, the force can be located at the center of the adjacent tooth to prevent the adjacent tooth from being offset and tilted in other directions. Of course, the adjacent tooth adaptation structure 5 is provided with an adaptive splint 53 in other directions for fixation, which can also prevent the adjacent tooth from being offset or tilted.

[0058] The elastic part 62 can be made of orthodontic strong steel wire or orthodontic strong spring. The elastic part 62 is installed on the fixed cylinder 61, so that an elastic force is exerted on the wall of the adjacent teeth. The elastic force is directed in the direction away from the missing position, so that the adjacent teeth are subjected to force and reset in the direction away from the missing position, thereby achieving the effect of orthodontic resetting and correction on the adjacent teeth.

[0059] For further reference, Figure 3 As shown, a reset portion 63 is also slidably connected in the fixed cylinder 61; the elastic portion 62 abuts against the fastening portion 64 at one end and against the reset portion 63 at the other end, and applies elastic force to make the reset portion 63 abut against the adjacent tooth. The reset portion 63 can adopt a reset cylinder and a reset plate, and the reset cylinder is plugged into the fixed cylinder 61, so that the reset cylinder can drive the reset plate to move along the fixed cylinder 61, and the elastic portion 62 is located at the fixed cylinder 61, providing elastic force to the reset plate and the reset cylinder, and the reset plate is in contact with the adjacent tooth.

[0060] The purpose of setting the resetting portion 63 is to increase the contact area with the adjacent teeth, so that the adjacent teeth are subjected to force more evenly and avoid single-point force on the adjacent teeth. Using only the elastic portion 62 to contact the adjacent teeth can easily damage the adjacent teeth. Therefore, when the resetting portion 63 slides along the fixed tube 61, the elastic force of the elastic portion 62 pushes the resetting portion 63 toward the adjacent teeth, thereby providing a force for resetting the adjacent teeth, so that orthodontic correction can be performed while maintaining the resetting force for a long time.

[0061] Further, refer to Figure 3As shown, the adjacent tooth reduction structure 6 also includes a fastening portion 64 and a third locking portion; the fastening portion 64 is plugged into the fixed tube 61, the third locking portion 65 is screwed into the threaded hole and abuts against the fastening portion 64, the fastening portion 64 can adopt a fastening rod, and the third locking portion 65 can adopt a third bolt. The fastening portion 64 is arranged at one end of the fixed tube 61 away from the adjacent tooth, one end of the elastic portion 62 is located in the fixed tube 61 and abuts against the fastening portion 64, and the other end extends out of the fixed tube 61 and abuts against the reduction portion 63 or the adjacent tooth, and the elastic portion 62 provides a force to push the reduction portion 63 or the adjacent tooth to reduce.

[0062] After the adjacent teeth are gradually repositioned, the elastic portion 62 will relax and gradually lose its thrust, so a fastening portion 64 is provided. The function of the fastening portion 64 is to apply pressure to the elastic portion 62, thereby compressing the elastic portion 62 and adjusting the elastic force of the elastic portion 62. Specifically, the fastening portion 64 can be pushed, and the fastening portion 64 moves along the fixing tube 61 and presses the elastic portion 62, so that the elastic portion 62 continues to maintain or increase the elastic force on the repositioning portion 63 or the adjacent teeth, so that the adjacent teeth are displaced until they are restored to their original physiological positions.

[0063] After the elastic force of the elastic portion 62 is adjusted, the fastening portion 64 is rotated and pressed through the third locking portion 65 and the threaded hole, so that the position of the fastening portion 64 is fixed, providing a stable compression effect on the elastic portion 62 .

[0064] In some embodiments, the contact surfaces of the base structure 2, the vertical adaptation structure 3, the adjacent tooth adaptation structure 5 and the adjacent tooth reduction structure 6 are all provided with friction patterns. Specifically, the friction patterns are arranged at the contact surface between the working part 22 and the adaptation sleeve 32, the contact surface between the transverse joint part 52 and the support member 4, and the contact surface between the fastening part 64 and the fixed tube 61. The friction patterns can increase the friction between the contact surfaces, thereby further improving the stability of the connection.

[0065] In some embodiments, reference Figure 4 As shown, the working part 22, the fastening part 64 and the support member 4 are all provided with a limiting groove 221, a friction plate 311 is provided in the limiting groove 221, a pivot groove 312 is provided on the friction plate 311, the first locking part 31, the second locking part 51 and the third locking part 65 are all pivotally connected to the corresponding pivot groove 312, and the illustration of this embodiment takes the working part 22 and the first locking part 31 as an example.

[0066] The friction plate 311 is slidably connected to the limiting groove 221, and the surface of the friction plate 311 and the inner wall of the limiting groove 221 are also provided with friction patterns. The friction plate 311 can increase the contact area between the first locking portion 31, the second locking portion 51 and the third locking portion 65 and the corresponding structure, thereby increasing the friction force to improve the tightness of the connection and prevent the looseness of each structure during the use of the combined tool.

[0067] Among them, the limiting groove 221 can adopt a T-shaped groove, and the first locking part 31, the second locking part 51 and the third locking part 65 can extend from the vertical groove of the T-shaped groove without affecting the movement of the friction plate 311. The friction plate 311 can be a circular plate or a rectangular plate, depending on the needs.

[0068] In some embodiments, when there are adjacent teeth on both sides of the missing position, a connecting frame can be set on the top of the adaptation sleeve 32, and two groups of support members 4, as well as adjacent tooth adaptation structures 5 and adjacent tooth reduction structures 6 on the support members 4 are set on the connecting frame, so that the adjacent teeth on both sides can be reduced and corrected synchronously.

[0069] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
