Description

Technical Field

[0001] This application relates to the field of medical device technology, specifically to a shaping system for treating proximal cavities of two teeth and its application. Background Technology

[0002] Interproximal caries is a highly prevalent and insidious type of dental caries. The lesions occur between the contact areas of two teeth and are difficult to detect in the early stages through routine examinations. Due to the special anatomical structure of the interproximal surfaces of teeth, the lesions progress much faster than on other tooth surfaces. By the time of clinical diagnosis, the tooth structure of two adjacent teeth has often been damaged simultaneously, forming the typical destructive pattern of "double interproximal caries".

[0003] Currently, the clinical approach to restoring "proximal cavities in both teeth" involves a single-tooth, staged restoration approach. This requires restoring the proximal morphology of one tooth first, followed by restoration of the other. This process is not only cumbersome, time-consuming, and labor-intensive, but also results in poor morphological restoration and presents a challenge in ensuring the coordination of the proximal morphologies of the two teeth. Even though existing technologies disclose the use of double-shaped pieces for the restoration of proximal cavities in both teeth, the clamping method used in existing single-tooth restorations cannot achieve precise restorative results and suffers from low treatment efficiency.

[0004] Therefore, there is an urgent need for those skilled in the art to develop an integrated solution that is easy to operate, improves diagnostic and treatment efficiency, and can simultaneously address the proximal morphology of two teeth. Summary of the Invention

[0005] In view of this, in order to solve or partially solve the above problems, this application provides a forming system and application method for treating proximal cavities of two teeth. The forming system forms a specific dual-forming-piece synchronous pressure structure through forming piece assemblies and matching forming clamp assemblies, thereby achieving one-time precise repair of proximal cavities of two teeth.

[0006] To achieve the above objectives, one embodiment of this application provides a shaping system for treating proximal cavities of two teeth, including a shaping sheet assembly and a matching shaping clamp assembly. The shaping sheet assembly includes two shaping sheets connected back-to-back, each shaping sheet being an arc-shaped thin sheet, a pressing member pressed against the end of the arc-shaped thin sheet, and a wedge-shaped rubber pad located in the area where the pressing member and the two shaping sheets intersect and close. The shaping 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. Under the adjustment operation of the adjustment structure, the clamping claw structure opens and closes, and pressure is applied to the two shaping sheets through the pressing member and the wedge-shaped rubber pad, so that the two shaping sheets fit tightly against the proximal surfaces of the two teeth.

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

[0008] Furthermore, the first pressing member includes a first pressing tube body and a first pressing block connected to both ends of the first pressing tube body; the second pressing member includes a second pressing tube body and a second pressing block 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 area space formed by the pressing member and the double-molded sheet, so that under the pressure of the pressing member, the wedge-shaped rubber pad applies pressure to the outer surface of the double-molded sheet from all directions.

[0010] Furthermore, the first pressing tube and the second pressing tube are provided with multiple slots for connecting and fixing the wedge-shaped rubber pad, the clamp of the claw structure, and for adjusting and fixing the position of the first pressing block and the second pressing block.

[0011] Furthermore, the wedge-shaped rubber pad has an insertion protrusion on its surface near the first pressing tube body and the second pressing tube body, and the insertion protrusion is inserted into one of the slots of the first pressing tube body and the second pressing tube body.

[0012] Furthermore, the gripper structure includes a first gripper, a second gripper symmetrically arranged with respect to the first gripper, and an arc-shaped connecting section for connecting the first gripper and the second gripper. Both ends of the arc-shaped connecting section are provided with protrusions on the inner side of the connection points with the first gripper and the second gripper, respectively, and the protrusions are provided with rotating holes.

[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 threaded, and the other end is rotatably connected to the connecting rod. A through hole is provided in the middle of the arc-shaped connecting section. After one end of the adjusting screw passes 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. Under the screwing of the nut rotating head, the first clamp and the second clamp open and close.

[0015] Another aspect of this application provides a method of applying the shaping system for treating proximal cavities of two teeth, comprising the following steps:

[0016] Step 1: Select the appropriate size of double-shaped sheet according to the size of the affected tooth to achieve the effect of surrounding the proximal surfaces of the two teeth, with the lower part of the arc-shaped sheet placed below the gingival wall of the cervical defect of the proximal surfaces of the two teeth;

[0017] Step 2: Install the pressing component on the jaws of the clamping structure of the forming clamp assembly, and insert the wedge-shaped rubber pad onto the pressing component. Tighten the clamping structure by rotating the adjusting structure of the forming clamp assembly. Apply pressure to the double forming piece through the pressing component and the wedge-shaped rubber pad to make the double forming piece fit tightly against the proximal surfaces of the two teeth, so that the double forming piece fits tightly against the cavity gingival wall.

[0018] Step 3: Clean and dry the cavity, then perform direct bonding repair with composite resin.

[0019] Compared with the prior art, the advantages of this application are as follows:

[0020] This application provides a shaping system for treating proximal cavities of two teeth. The shaping system forms a specific dual-shaping-piece synchronous pressure structure through a shaping piece assembly and a matching shaping clamp assembly, enabling one-time precise repair of proximal cavities of two teeth and solving the technical problem of low diagnostic and treatment efficiency of existing proximal cavity repair techniques.

[0021] Specifically, the core technical solution of this application, formed by "back-to-back connection of double-molded sheets + pressing component and wedge-shaped rubber pad for pressure + screw adjustment structure and clamp structure", has the following significant advantages compared with existing adjacent hole repair technologies:

[0022] This application utilizes a synchronous wrapping design of two molding pieces bonded or welded back-to-back, combined with a quick-assembly and disassembly gripper structure, to achieve one-time molding of proximal cavities of two teeth. This avoids the secondary positioning errors of traditional split molding pieces, greatly improves the efficiency of diagnosis and restoration, and breaks through the efficiency bottleneck of proximal cavity restoration.

[0023] Furthermore, this application solves the problem of adjacent surface morphology coordination by setting a wedge-shaped rubber pad in the closed area formed by the pressing member and the double molding sheet, forming a three-dimensional uniform pressure field under the clamping of the claw structure, which acts on the adjacent surfaces of two adjacent teeth.

[0038] Example 1

[0039] See Figure 1 As shown, this embodiment provides a shaping system for treating proximal cavities of two adjacent teeth. The shaping system includes a shaping sheet assembly 2 and a matching shaping clamp assembly 3 for repairing proximal cavities of a first adjacent tooth 11 and a second adjacent tooth 12. The shaping sheet assembly 2 includes two shaping sheets 21 connected back-to-back. Each shaping sheet is an arc-shaped thin sheet. A pressing member 23 is pressed against the end of the arc-shaped thin sheet. A wedge-shaped rubber pad 22 is located in the area where the pressing member 23 and the two shaping sheets 21 intersect and close. The shaping clamp assembly 3 includes an adjustment 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. Under the adjustment operation of the adjustment structure 31, the clamping claw structure 32 is driven to open and close. The pressing member 23 and the wedge-shaped rubber pad 22 apply pressure to the two shaping sheets 21, so that the two shaping sheets fit tightly against the proximal surfaces of the two teeth.

[0040] Utilizing the technical solution of this embodiment, the synchronous wrapping design of the double molding pieces 21 bonded or welded back-to-back, combined with the quick-assembly and disassembly clamping structure 32, enables the one-time forming of proximal cavities of two teeth, avoiding secondary positioning errors of traditional split molding pieces and greatly improving the efficiency of diagnosis and restoration. Furthermore, by placing the wedge-shaped rubber pad 22 in the closed area formed by the pressing member 23 and the double molding piece 21, a three-dimensional uniform pressure field is formed under the clamping of the clamping structure 32, acting on the proximal surfaces of two adjacent teeth, solving the problem of proximal surface morphological coordination.

[0041] Example 2

[0042] Combination Figure 2 , Figure 3 , Figure 5As shown, based on Embodiment 1, in 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, with two first pressing blocks 232a movably connected to both ends of the first pressing tube 231a; the second pressing member 23b includes a second pressing tube 231b, with two second pressing blocks 232b movably connected to both ends of the second pressing tube 231b. The pressing tube 231b has multiple slots 2310 spaced 0.5-2mm apart, used to achieve: ① position adjustment of the wedge-shaped rubber pad; ② quick connection of the gripper structure; ③ sliding fixation of the pressing blocks.

[0043] Specifically, the wedge-shaped rubber pad 22 has an insertion protrusion 220 on its 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 achieve position adjustment and fixation of the wedge-shaped rubber pad 22. The clamping head of the gripper structure is provided with an elastic snap-fit ​​insertion protrusion, allowing the gripper structure to be quickly disassembled and connected to the slot 2310 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 and detachably connected to the slot 2310. When it is necessary to slide the pressing block 232, 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 released 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.

[0044] To enhance the overall fit and coverage of the dual-molding sheet on the proximal surfaces of the teeth, the position of the pressing blocks 232 of the pressing member 23 is adjusted so that the shape of the area formed by the dual-molding sheet 21 and the pressing block 232 at both ends matches the shape of the wedge-shaped pad 22. This ensures that under the pressure of the pressing member 23, the wedge-shaped pad 22 and the pressing blocks 232 at both ends apply pressure to the outer surface of the dual-molding sheet from all directions. 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 pad 22.

[0045] It should be noted that, in this embodiment of the application, each side of the double-molded sheet 21 can be made of a 0.03-0.06mm thick medical stainless steel arc-shaped sheet, welded or bonded back-to-back to form a symmetrical structure. The thickness of the connecting section in the middle is consistent with the thickness of each side of the molded sheet, and its curvature matches the curve of the proximal surface of the tooth, so that it can simultaneously surround the proximal area of ​​two adjacent teeth. Generally, the double-molded sheet 21 is designed in three sizes: large, medium, and small (S / M / L). The appropriate size of the double-molded sheet is selected according to the size of the affected tooth to achieve the effect of surrounding the proximal surface of the two teeth, and to ensure that the lower part of the arc-shaped sheet can completely cover the gingival wall below the cervical defect of the proximal surface of the two teeth by 0.5-1mm.

[0046] The wedge-shaped pad 22 in this embodiment is made of medical-grade silicone. Its wedge-shaped body 221 has an isosceles triangular cross-section and abuts against the connection point of the bi-molded sheet. Figure 5 As shown, the wedge-shaped main body 221 has main body side wings 222 on both sides. The bending arc of the connection between the wedge-shaped main body 221 and the main body side wings 222 on both sides is consistent with the bending arc of each side molding piece. Combined with the sliding adjustment and fixation of the pressing blocks at both ends of the pressing tube, it ensures that the wedge-shaped rubber pad 22 is completely matched with the spatial shape enclosed by the pressing component and the molding piece, which facilitates enhancing the overall fit and wrapping feel of the double molding piece on the proximal surfaces of the teeth. The surface of the wedge-shaped rubber pad 22 near the pressing tube has an insertion protrusion 220, which can be inserted into different slots 2310 to achieve position fixation. When pressed, it can produce an elastic deformation of 0.1-0.5mm, ensuring uniform pressure on the outer surface of the molding piece.

[0047] Example 3

[0048] like Figure 1 , Figure 2 As shown, based on Embodiment 1 and Embodiment 2, in a preferred embodiment, the gripper structure 32 includes a first gripper 321a, a second gripper 321b symmetrically arranged with the first gripper 321a, and an arc-shaped connecting segment 322 for connecting the first gripper 321a and the second gripper 321b. Both ends of the arc-shaped connecting segment 322 are provided with protrusions 320 on the inner side of the connection between the first gripper 321a and the second gripper 321b, respectively. The protrusions 320 are provided with rotating holes 3201.

[0049] 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 by a commonly used pin insertion method in the rotating hole 3201.

[0050] One end of the adjusting screw 311 is threaded, and the other end is rotatably connected to the connecting rod 313. A through hole is provided in the middle of the arc-shaped connecting section 322. After one end of the adjusting screw 311 passes 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. Under the screwing of the nut rotating head 312, 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 component 23.

[0051] Example 4

[0052] Another aspect of this application provides a method of applying the shaping system for treating proximal cavities of two teeth, comprising the following steps:

[0053] Step 1: Select the appropriate size of the double-shaped sheet 21 according to the size of the affected tooth to achieve the effect of surrounding the proximal surfaces of the two teeth. The lower part of the arc-shaped sheet is placed 0.5-1mm below the gingival wall of the neck defect of the proximal surfaces of the two teeth, which can be confirmed by observation with an endoscope.

[0054] Step 2: Install the first pressing component and the second pressing component on the jaws of the first and second clamps respectively, and insert the two wedge-shaped rubber pads into the first pressing component and the second pressing component respectively. Specifically, the wedge-shaped rubber pads are fixed by inserting the insertion protrusion 220 of the wedge-shaped rubber pads into the corresponding slots 2310. Then, place them on the double-forming plate. The pressing blocks at both ends of the pressing tube first contact the ends of the double-forming plate. The wedge-shaped rubber pads are arranged in the closed area formed by the pressing tube, the pressing blocks at both ends, and the double-forming plate. By turning the adjustment structure of the forming clamp assembly, the clamp structure is tightened. The wedge-shaped rubber pads 22 undergo elastic deformation as the pressure increases, applying a uniform lateral force to the double-forming plate. The double-forming plate gradually conforms to the tooth surface until it forms a seamless fit with the cavity gingival wall, which can be confirmed by checking with a periodontal probe.

[0055] Step 3: Clean and dry the cavity, then perform direct bonding repair with composite resin.

[0056] In summary, the overall technical solution formed by "double-molded sheet back-to-back connection + pressing component and wedge-shaped rubber pad pressure + screw adjustment structure and clamp structure" has the following significant advantages over existing proximal cavity repair technology. Clinical verification shows that this system can shorten the repair time of proximal cavities of two teeth by 40%, reduce the incidence of food impaction to below 8%, and control the incidence of secondary caries to within 5%.
