Description

Technical Field

[0001] This utility model relates to a splicing modular denture, and more particularly to a splicing modular denture, belonging to the field of dental technology. Background Technology

[0002] Modular prostheses are an advanced denture design that uses a modular assembly method to flexibly adapt to different patient oral conditions. Their advantages include simple and quick installation; the precise connection design ensures that the modules fit together tightly, guaranteeing both denture stability and ease of future maintenance and replacement. Furthermore, modular prostheses offer significant improvements in aesthetics and comfort, seamlessly integrating into the patient's oral environment and restoring chewing function and confidence. At the same time, the materials used are safe and harmless, posing no adverse effects on oral health.

[0003] A search revealed a Chinese patent application (patent number 202220596558.0) disclosing a modular denture assembly, comprising dentures and collars. Each denture has a collar fixed to its outer wall, and the outer wall of each collar is provided with a connecting component. This connecting component includes a connecting rod, a conical block, and sleeve plates. Multiple sleeve plates are fixed to the left and right sides of the outer wall of the collar. A connecting rod passes through the interior of each sleeve plate, with a clearance fit between the connecting rod and the sleeve plate. The inner side of each conical block is tightly fitted to the sleeve plate. This modular denture assembly, through the cooperation of the conical head, denture, bolt head, connecting rod, sleeve plate, support rod, and conical block, allows the denture with conical heads on both sides to be installed above the bolt head. Then, the connecting rod is inserted into the interior of the corresponding sleeve plate, and subsequently, the support rod with the conical block is inserted into the internal notch of the connecting rod. This, through the inclined plane and sleeve plates, achieves tension between adjacent dentures, facilitating the splicing of multiple dentures and avoiding the problem of inconvenient splicing and quick installation of existing multiple dentures.

[0004] The dentures in the aforementioned patent have the following shortcomings when disassembling: when adjacent dentures are assembled, they are in a taut state, but when replacing adjacent dentures, the taut state makes it difficult to disassemble them.

[0005] Therefore, there is an urgent need to improve a modular denture to solve the aforementioned problems. Summary of the Invention

[0006] The purpose of this invention is to provide a modular denture. When the first bolt is loosened and separated from the top of the support post, the spring deforms and pushes the limiting frame upward. The upward movement of the limiting frame causes the first and second auxiliary teeth to move away from the gums. The second bolt is loosened and disengaged from the insert. The first and second auxiliary teeth can be easily removed with medical tools. New auxiliary teeth can be taken out and installed by following the reverse disassembly steps.

[0007] To achieve the above objectives, the main technical solution adopted by this utility model includes: a splicing combination denture, comprising symmetrically distributed main teeth and a first auxiliary tooth and a second auxiliary tooth spliced ​​between the main teeth. The outer side of each main tooth has an inlay groove, and the interior of the inlay groove is connected to a clamp via a sleeve. The tops of the main teeth, the first auxiliary tooth, and the second auxiliary tooth are all wrapped with a limiting frame via limiting grooves. The bottom of the limiting frame is provided with symmetrical sliding rods. The top of each main tooth has a second sliding groove, and the interior of each second sliding groove contains a spring, a first sleeve, a second sleeve, and a support column. The top of the spring abuts against the bottom of the limiting frame. Symmetrical first bolts and second bolts are distributed through the top of each limiting frame.

[0008] Preferably, the top of the main tooth is provided with symmetrical first sliding grooves, the first sliding grooves are wrapped around the outside of the slide rod, and the bottom of the slide rod is fitted with the inside of the first sliding groove by a stop block.

[0009] Preferably, the top of the first slide groove is provided with a groove, and the inner side of the groove wraps around the outside of the slide rod. The top of the slide rod is threadedly connected to the bottom of the limiting frame, and the top of the stop block is threadedly connected to the bottom of the slide rod.

[0010] Preferably, the interior of the second groove is fixedly connected to the bottom of the first sleeve, the interior of the first sleeve is penetrated by the second sleeve, the top end of the second sleeve is disposed at the bottom end of the limiting frame, and the interior of the spring penetrates the exterior of the first sleeve.

[0011] Preferably, the outside of the support column extends through the inside of the second sleeve, and the top of the support column is provided with an internal thread, which is screwed into the bottom thread of the first bolt.

[0012] Preferably, both the first auxiliary tooth and the second auxiliary tooth have insert blocks on their inner sides at the top, and the insert blocks are inserted inside the limiting frame.

[0013] Preferably, the top of the insert has an internal thread, and the interior of the internal thread is screwed into the bottom thread of the second bolt.

[0014] This utility model has at least the following beneficial effects: by loosening the first bolt, the bottom of the first bolt separates from the top of the support column, the spring deforms and pushes the limiting frame and other parts upward, the limiting frame disengages from the limiting groove, and the limiting of the first and second auxiliary teeth is released. Since the top of the limiting frame is connected to the insert block by the threaded engagement of the second bolt, the upward movement of the limiting frame drives the first and second auxiliary teeth away from the gums, the second bolt is loosened and disengaged from the insert block, the first and second auxiliary teeth are removed with medical tools, and new auxiliary teeth are taken and installed according to the reverse disassembly steps.

Detailed Implementation

[0022] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0023] Examples, such as Figures 1-5 As shown, a splicing modular denture includes symmetrically distributed main teeth 1 and a first auxiliary tooth 4 and a second auxiliary tooth 8 spliced ​​between the main teeth 1. The outer side of the main teeth 1 is provided with an inlay groove 101. The inside of the inlay groove 101 is connected to a clamp 3 through a sleeve 2. The tops of the main teeth 1, the first auxiliary tooth 4 and the second auxiliary tooth 8 are all wrapped with a limiting frame 5 through a limiting groove 102. The bottom of the limiting frame 5 is provided with symmetrical sliding rods 104. The top of the main teeth 1 is provided with a second sliding groove 106. The inside of the second sliding groove 106 contains a spring 110, a first sleeve 107, a second sleeve 109 and a support column 108. The top of the spring 110 abuts against the bottom of the limiting frame 5. The top of the limiting frame 5 is provided with symmetrical first bolts 111 and second bolts 7.

[0024] Furthermore, the inner part of the second slide groove 106 is fixedly connected to the bottom of the first sleeve 107, the inner part of the first sleeve 107 is penetrated by the second sleeve 109, the top end of the second sleeve 109 is set at the bottom end of the limit frame 5, the inner part of the spring 110 penetrates the outer part of the first sleeve 107, the outer part of the support column 108 penetrates the inner part of the second sleeve 109, the top of the support column 108 is provided with an internal thread, and the internal thread is screwed into the bottom thread of the first bolt 111.

[0025] First, loosen the first bolt 111 to detach it from the top of the support column 108. The spring 110 pushes the limit frame 5 upward inside the first slide groove 103. The limit frame 5 slides along the inside of the first sleeve 107 through the second sleeve 109. At this time, it prevents the spring 110 from bending during deformation. At the same time, the first sleeve 107 and the second sleeve 109 can ensure that the limit frame 5 is more stable when moving upward, and prevent the limit frame 5 from shaking.

[0026] Furthermore, the top of the main tooth 1 is provided with symmetrical first grooves 103, the first grooves 103 are wrapped around the outside of the slide rod 104, and the bottom of the slide rod 104 is fitted with the inside of the first grooves 103 through the stop block 105.

[0027] The upward movement of the limiting frame 5 causes the slide rod 104 to slide inside the first slide groove 103. During the upward movement of the slide rod 104, the bottom stop 105 plays a limiting role to prevent the slide rod 104 from disengaging from the first slide groove 103. Therefore, the limiting frame 5 can be connected with the main tooth 1. This connection facilitates the upward movement of the first auxiliary tooth 4 and the second auxiliary tooth 8.

[0028] The first slide groove 103 has a groove at its top, and the inner side of the groove wraps around the outside of the slide rod 104. The top of the slide rod 104 is threadedly connected to the bottom of the limit frame 5, and the top of the stop block 105 is threadedly connected to the bottom of the slide rod 104.

[0029] When the slide rod 104 slides inside the first slide groove 103, the stability of the slide rod 104 can be increased by the covering of the groove. At the same time, the slide rod 104 provides secondary stability when the limit frame 5 moves upward, preventing the spring 110 from shaking significantly when pushing the limit frame 5, and ensuring that the limit frame 5 is more stable.

[0030] Furthermore, the inner sides of the top of the first tooth 4 and the second tooth 8 are provided with insert blocks 6, which are inserted into the limit frame 5. The top of the insert block 6 is provided with internal threads, and the inside of the internal threads is screwed into the bottom thread of the second bolt 7.

[0031] Spring 110 pushes the limiting bracket 5 to move the first auxiliary tooth 4 and the second auxiliary tooth 8 upward. After moving upward, the bottom ends of the first auxiliary tooth 4 and the second auxiliary tooth 8 will detach from the gum. By loosening the second bolt 7, they will be separated from the inside of the insert block 6. The first auxiliary tooth 4 and the second auxiliary tooth 8 can be easily removed using medical tools, which is also conducive to replacing new auxiliary teeth.

[0032] like Figures 1-5 As shown in this embodiment, the principle of a modular denture is as follows:

[0033] When replacing the first auxiliary tooth 4 and the second auxiliary tooth 8, first loosen the first bolt 111 that penetrates the top of the main tooth 1. The bottom end of the first bolt 111 will disengage from the top of the support column 108. The spring 110 inside the second slide 106 pushes the limiting frame 5 upward. The connection between the second bolt 7 and the insert block 6 is maintained, so the first auxiliary tooth 4 and the second auxiliary tooth 8 will also move. The bottom ends of the first auxiliary tooth 4 and the second auxiliary tooth 8 will move away from the gum line. By loosening the second bolt 7, they will disengage from the top of the insert block 6. Use medical tools to clamp the first auxiliary tooth 4 and the second auxiliary tooth 8. At this time, the insert block 6 will disengage from the slot, so that the first auxiliary tooth 4 and the second auxiliary tooth 8 are completely disengaged from the bottom of the limiting frame 5. Take the new auxiliary tooth and install it according to the reverse disassembly steps. Apply pressure to the limiting frame 5 and move it into the limiting groove 102. At this time, the second sleeve... 109 slides inside the first sleeve 107. The first sleeve 107 and the second sleeve 109 ensure that the limiting frame 5 is more stable when moving, and at the same time prevent the spring 110 from bending when it deforms. When the limiting frame 5 feels resistance, the first bolt 111 is screwed into the top thread of the support column 108 to ensure that the limiting frame 5 is connected to the main tooth 1. When replacing the main tooth 1, firstly, the clamp 3 is disengaged from the patient's tooth, and the first bolt 111 is loosened from the support column 108. At this time, the main tooth 1 will be completely disengaged from the limiting frame 5. Then, the slide rod 104 is rotated to disengage from the bottom of the limiting frame 5, thereby completing the disassembly of the main tooth 1. The slide rod 104 inside the new main tooth 1 is screwed into the bottom thread of the limiting frame 5, and then the new main tooth 1 is installed with the limiting frame 5. The clamp 3 is then clamped onto the patient's tooth.
