Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a forming system for treating bilateral interproximal cavities and its application. Background Art

[0002] Interproximal caries, a highly prevalent and insidious type of dental caries, develops between the contact areas of two teeth, making it difficult to detect through routine examinations in the early stages. Due to the unique anatomical structure of interproximal surfaces, the disease progresses significantly faster than on other tooth surfaces. By the time a diagnosis is made, the dental tissues of both adjacent teeth have already been damaged, resulting in a typical pattern of "double interproximal cavities."

[0003] The current clinical restoration method for "double-tooth interproximal cavities" is to use a single-tooth, staged restoration plan, which requires first restoring the interproximal morphology of one tooth before trimming the other. This is not only cumbersome and time-consuming, but also results in poor restoration. It is also challenging to ensure the coordination of the interproximal morphology of the two teeth. Even though the prior art discloses the use of double-molding sheets for the restoration of double-tooth interproximal cavities, combined with the existing clamping method of single-tooth restoration, it cannot achieve a precise restoration effect and has the technical problem of low diagnosis and treatment efficiency.

[0004] Therefore, for those skilled in the art, there is an urgent need to develop an integrated solution that is easy to operate, helps improve diagnosis and treatment efficiency, and can simultaneously treat the adjacent surface morphologies of two teeth. Summary of the Invention

[0005] In view of this, in order to solve or partially solve the above problems, the present application provides a forming system and application method for treating bilateral interproximal cavities. A forming system with a specific dual-forming-sheet synchronous pressurization structure is formed by a forming sheet assembly and a matching forming clip assembly to achieve a one-time precise restoration of bilateral interproximal cavities.

[0006] To achieve the above-mentioned purpose, an embodiment of the present application provides, on the one hand, a forming system for treating bilateral proximal cavities, including a forming sheet assembly and a matching forming clamp assembly; the forming sheet assembly includes two forming sheets connected back to back, the forming sheet is an arc-shaped thin sheet, a pressing member crimped to the end of the arc-shaped thin sheet, and a wedge-shaped rubber pad located in the cross-closed area between the pressing member and the two forming sheets; the forming clamp assembly includes an adjustment structure and a clamping claw structure, the clamping head of the clamping claw structure is detachably connected to the pressing member, and under the adjustment operation of the adjustment structure, the clamping claw structure is driven to open and close, and pressure is applied to the two forming sheets through the pressing member and the wedge-shaped rubber pad, so that the two forming sheets are tightly fitted on the proximal surfaces of the two teeth.

[0007] Furthermore, the pressing member includes a first pressing member located on the labial side of the tooth and a second pressing member located on the lingual side of the tooth.

[0008] Furthermore, the first pressing member includes a first pressing tube body and first pressing blocks connected to both ends of the first pressing tube body; the second pressing member includes a second pressing tube body and second pressing blocks connected to both ends of the second pressing tube body.

[0009] Furthermore, the shape of the wedge-shaped rubber pad matches the shape of the regional space enclosed by the pressing member and the double-molded sheet, so that under the pressure of the pressing member, the wedge-shaped rubber pad applies omnidirectional pressure to the outer surface of the double-molded sheet.

[0010] Furthermore, a plurality of slots are provided on the first pressing tube body and the second pressing tube body for connecting and fixing the wedge-shaped rubber pad, the chuck of the clamping structure, and for adjusting and fixing the position of the first pressing block and the second pressing block.

[0011] Furthermore, an inserting protrusion is provided on the surface of the wedge-shaped rubber pad close to the first pressing tube body and the second pressing tube body, and the inserting protrusion is inserted into one of the slots of the first pressing tube body and the second pressing tube body.

[0012] Furthermore, the clamping structure includes a first clamping jaw, a second clamping jaw symmetrically arranged with the first clamping jaw, and an arc-shaped connecting section for connecting the first clamping jaw and the second clamping jaw. Both ends of the arc-shaped connecting section are respectively provided with protrusions on the inner side of the connection with the first clamping jaw and the second clamping jaw, and a rotating hole is opened on the protrusion.

[0013] Furthermore, the adjustment structure includes a nut rotating head, an adjusting screw, and a connecting rod connected to the adjusting screw and the rotating hole.

[0014] Furthermore, one end of the adjusting screw is provided with a thread, and the other end is rotationally connected to the connecting rod. A through hole is opened in the middle of the arc-shaped connecting section. After one end of the adjusting screw is passed through the through hole, the nut rotating head is screwed onto the thread, and the nut rotating head abuts against the through hole of the arc-shaped connecting section. When the nut rotating head is screwed, the first jaw and the second jaw are driven to open and close.

[0015] Another embodiment of the present application provides an application method of the shaping system for treating bilateral interproximal cavities, comprising the following steps: Step 1: Select a suitable double-molded sheet according to the size of the affected teeth to surround the adjacent surfaces of the two teeth, and place the lower part of the curved sheet below the gingival wall of the adjacent cervical defect of the two teeth; Step 2: Install the pressing member on the clamping head of the clamping claw structure of the forming clamp assembly, and insert the wedge-shaped rubber pad onto the pressing member. Tighten the clamping claw structure by screwing the adjusting structure of the forming clamp assembly.

DETAILED DESCRIPTION

[0021] Several embodiments of the present application will be disclosed below in the form of drawings, which clearly and completely describe the technical solution of the present application and constitute a part of the specification of the present application. The drawings are used to provide a further understanding of the present application. The schematic embodiments and descriptions of the present application are used to explain the present invention and do not constitute an improper limitation on the application.

For example, "connection" can refer to a fixed connection, a detachable connection, or an integral connection, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0024] In addition, the technical solutions between the various embodiments of the present application can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0025] Example 1 See Figure 1As shown, this embodiment provides a forming system for treating double-tooth interproximal cavities, the forming system comprising a forming sheet assembly 2 and a matching forming clamp assembly 3, for repairing the interproximal cavities of a first adjacent tooth 11 and a second adjacent tooth 12; the forming sheet assembly 2 comprises double forming sheets 21 connected back to back, the forming sheet being an arc-shaped thin sheet, a pressing member 23 crimped to the end of the arc-shaped thin sheet, and a wedge-shaped rubber pad 22 located in the cross-closed area between the pressing member 23 and the double forming sheet 21; the forming clamp assembly 3 comprises an adjusting structure 31 and a clamping claw structure 32, the clamping head of the clamping claw structure 32 is detachably connected to the pressing member 23, and under the adjustment operation of the adjusting structure 31, the clamping claw structure 32 is driven to open and close, and pressure is applied to the double forming sheet 21 through the pressing member 23 and the wedge-shaped rubber pad 22, so that the double forming sheet is tightly fitted to the interproximal surfaces of the two teeth.

[0026] Utilizing the technical solution of this embodiment, this embodiment achieves the one-time formation of two adjacent cavities through the synchronous wrapping design of dual forming sheets 21 bonded or welded back to back, combined with a quickly assembled and disassembled clamping structure 32. This avoids the secondary positioning errors of traditional split forming sheets and significantly improves the efficiency of diagnosis, treatment, and restoration. Furthermore, by placing the wedge-shaped rubber pad 22 in the closed area formed by the pressing member 23 and the dual forming sheets 21, a three-dimensional uniform pressure field is formed under the clamping of the clamping structure 32, acting on the adjacent surfaces of two adjacent teeth, solving the problem of adjacent surface morphological coordination.

[0027] Example 2 Combine Figure 2 、 Figure 3 、 Figure 5 As shown, based on Example 1, as a preferred embodiment, the pressing member 23 includes a first pressing member 23a located on the labial side of the teeth and a second pressing member 23b located on the lingual side of the teeth. The first pressing member 23a includes a first pressing tube 231a, which is movably connected to two first pressing blocks 232a at both ends of the first pressing tube 231a; the second pressing member 23b includes a second pressing tube 231b, which is movably connected to two second pressing blocks 232b at both ends of the second pressing tube 231b. The pressing tube 231 is provided with a plurality of slots 2310 with an interval of 0.5-2mm, which are used to realize: ① position adjustment of the wedge-shaped rubber pad; ② quick connection of the clamping structure; ③ sliding fixation of the pressing block.

[0028] Specifically, the wedge-shaped rubber pad 22 is provided with an insertion protrusion 220 on the surface near the pressing tube body 231. The insertion protrusion 220 is inserted into one of the slots 2310 of the pressing tube body 231 to adjust and fix the position of the wedge-shaped rubber pad 22. The clamping head of the clamping structure is provided with an elastically engaged insertion protrusion, so that the clamping structure can be quickly detached and connected to the slot 2310 opened in the middle section of the pressing tube body 231. The pressing block is provided with an elastic plug-in rod that is adapted to be detachably connected to the slot 2310. When the position of the pressing block 232 needs to be slidably moved, the elastic plug-in rod is pulled up to move the pressing block 232 to the appropriate position. At this time, the elastic plug-in rod can be loosened to insert the elastic plug-in rod into the slot 2310 of the pressing tube body 231, thereby achieving sliding fixation of the pressing block 232.

[0029] To enhance the overall fit and wrapping of the double-molded sheet against the adjacent tooth surfaces, the position of the pressing block 232 of the pressing member 23 is slidably adjusted to match the shape of the area enclosed by the double-molded sheet 21 with the shape of the wedge-shaped rubber pad 22. This allows the pressing member 23 to exert omnidirectional pressure on the outer surface of the double-molded sheet through the wedge-shaped rubber pad 22 and the pressing blocks 232 at both ends. Furthermore, the sliding adjustment width W2 of the pressing blocks 232 at both ends of the pressing tube 231 is consistent with the maximum lateral width W1 of the wedge-shaped rubber pad 22.

[0030] It should be noted that the forming sheets on each side of the double forming sheet 21 of the embodiment of the present application can be made of medical stainless steel curved thin sheets with a thickness of 0.03-0.06mm, welded or bonded back to back to form a symmetrical structure. The thickness of the middle connecting section is consistent with the thickness of the forming sheets on each side, and the curvature of the forming sheet matches the curve of the tooth's interproximal surface, which can simultaneously surround the interproximal area of ​​two adjacent teeth. Generally, the double forming sheet 21 is designed in three sizes (S / M / L): large, medium, and small. The appropriate size of double forming sheet is selected according to the size of the affected tooth to achieve the effect of surrounding the interproximal surfaces of both teeth and ensure that the lower portion of the curved thin sheet can completely cover the 0.5-1mm below the gingival wall of the interproximal cervical defect of both teeth.

[0031] The wedge-shaped rubber pad 22 of the embodiment of the present application is made of medical silicone material, and the cross section of the wedge-shaped main body 221 is an isosceles triangle shape, which abuts against the connection between the two molding sheets; Figure 5As shown, the wedge-shaped body 221 is flanked by body wings 222 on either side. The curvature of the connection between the wedge-shaped body 221 and the body wings 222 on either side matches the curvature of the molding sheet on each side. Combined with the sliding, adjustable fixation of the pressing blocks at both ends of the pressing tube, this ensures that the wedge-shaped rubber pad 22 perfectly matches the spatial form enclosed by the pressing member and the molding sheet, thereby enhancing the overall fit and wrapping of the dual molding sheets on the adjacent tooth surfaces. The wedge-shaped rubber pad 22 is provided with a plug-in protrusion 220 on the surface near the pressing tube, which can be inserted into different slots 2310 to secure its position. When subjected to pressure, it can produce an elastic deformation of 0.1-0.5 mm, ensuring uniform pressure on the outer surface of the molding sheet.

[0032] Example 3 like Figure 1 、 Figure 2 As shown, on the basis of Example 1 and Example 2, as a preferred embodiment, the clamping jaw structure 32 includes a first clamping jaw 321a, a second clamping jaw 321b symmetrically arranged with the first clamping jaw 321a, and an arc-shaped connecting section 322 for connecting the first clamping jaw 321a and the second clamping jaw 321b, and both ends of the arc-shaped connecting section 322 are respectively provided with a protrusion 320 on the inner side of the connection with the first clamping jaw 321a and the second clamping jaw 321b, and the protrusion 320 is provided with a rotating hole 3201.

[0033] Furthermore, the adjustment structure 31 includes a nut rotating head 312, an adjusting screw 311, and a connecting rod 313 connected to the adjusting screw 311 and the rotating hole 3201; specifically, the rotational connection between the connecting rod 313 and the protrusion 320 can be achieved through a commonly used connection method of a pin shaft inserted into the rotating hole 3201.

[0034] One end of the adjusting screw 311 is provided with a thread, and the other end is rotationally connected to the connecting rod 313. A through hole is opened in the middle of the arc-shaped connecting section 322. After one end of the adjusting screw 311 is passed through the through hole, the nut rotating head 312 is screwed onto the thread, and the nut rotating head 312 abuts against the through hole of the arc-shaped connecting section 322. When the nut rotating head 312 is screwed, the first clamping jaw 321a and the second clamping jaw 321b are driven to open and close, thereby realizing the clamping function of the pressing member 23.

[0035] Example 4 Another embodiment of the present application provides an application method of the shaping system for treating bilateral interproximal cavities, comprising the following steps: Step 1: Select a suitable type of double-molded sheet 21 according to the size of the affected teeth, so as to surround the adjacent surfaces of the two teeth, and place the lower part of the curved sheet 0.5-1 mm below the gingival wall of the adjacent cervical defect of the two teeth, which can be confirmed by endoscopy; Step 2: Install the first pressing member and the second pressing member on the clamping heads of the first clamping jaw and the second clamping jaw respectively, and insert the two wedge-shaped rubber pads on the first pressing member and the second pressing member respectively, specifically by inserting the inserting protrusions 220 of the wedge-shaped rubber pads 22 into the corresponding slots 2310 to fix the wedge-shaped rubber pads; then, place them on the double-molding sheet, and the pressing blocks at both ends of the pressing tube body first contact the ends of the double-molding sheet, and the wedge-shaped rubber pads are arranged in the closed area formed by the pressing tube body and the pressing blocks at both ends, and the double-molding sheet; by screwing the adjustment structure of the molding clamp assembly, the clamping jaw structure is tightened, and the wedge-shaped rubber pads 22 are elastically deformed as the pressure increases, applying a uniform lateral force to the double-molding sheet, and the double-molding sheet gradually fits the tooth surface until a seamless fit is formed with the cavity-shaped gingival wall, which can be confirmed by a periodontal probe inspection; Step 3: Clean and dry the cavity, and perform direct bonding and repair with composite resin.

[0036] In summary, the overall technical solution formed by "back-to-back connection of double forming sheets + pressing component and wedge-shaped rubber pad pressurization + screw adjustment structure and clamping claw structure" in this application has the following significant advantages compared with the existing interproximal cavity repair technology. Clinical verification shows that this system can shorten the repair time of bilateral interproximal cavities by 40%, reduce the incidence of food impaction to below 8%, and control the incidence of secondary caries within 5%.
