Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a dental implant. Background Art

[0002] Ti and its alloys have good biocompatibility, corrosion resistance and mechanical properties, and are the preferred materials for dental implant modules. However, most of the Ti implants currently used in clinical practice are dense structures, and their elastic modulus (105-110GPa) is significantly higher than that of natural human bone (0.02-30GPa). The mismatch of elastic modulus can lead to the "stress shielding" effect, causing bone absorption around the implant, causing aseptic loosening, falling off and fracture. In addition, the "stress shielding" effect can easily cause excessive micro-motion at the implant module-bone tissue interface, plaque accumulation, and then cause inflammation around the implant module, ultimately leading to implant failure.

[0003] By introducing a pore structure into the Ti alloy, the elastic modulus of the implant can be changed by adjusting the shape, size and distribution of the pores. The unique pore structure is also beneficial to the adhesion, proliferation and differentiation of cells, promoting the growth of bone tissue and achieving biological fixation. However, the introduction of the pore structure will significantly reduce the mechanical properties of the material, resulting in its strength being unable to meet the requirements of hard tissue implantation.

[0031] Please refer to Figure 1 A dental implant comprises a tooth 1, an implant module 2 is arranged at the bottom of the tooth 1, a convenient mounting structure 3 is arranged inside the implant module 2, and the tooth 1 is mounted inside the implant module 2 through the convenient mounting structure 3.

[0032] When in use, the implant module 2 is implanted inside the patient's gums. After the patient's gum wound has healed for a certain period of time, the tooth 1 can be installed inside the implant module 2 by setting the installation structure 3.

[0033] By setting the implant module 2, the mechanical properties can be guaranteed under the condition of high porosity, and on the other hand, the bionic design of the oral mandible can be met, so as to facilitate the adhesion, proliferation and differentiation of cells, promote the growth of bone tissue, and realize biological fixation;

[0034] At the same time, by setting the convenient installation structure 3, the convenience of installing the tooth 1 can be improved.

[0035] Embodiment 2:

[0036] This embodiment 2 is used to further disclose the specific structure of the implant module 2 on the premise of the above embodiment. Through the coordination of the implant module 2 and the structure in the above embodiment, an axial gradient porous design is achieved. On the one hand, its mechanical properties can be guaranteed while meeting the high porosity, and on the other hand, the bionic design of the oral mandible is met, which is beneficial to the adhesion, proliferation and differentiation of cells, promotes the growth of bone tissue, and realizes biological fixation.

Specifically, Figure 3-Figure 6 As shown, the installation structure 3 includes a fixing column 8 and a limiting ring 9, a circular reserved groove is opened on the inner side of the implant neck 4, and a square reserved groove is also opened on the inner bottom of the implant neck 4, and the square reserved groove and the circular reserved groove are connected, and the bottom of the tooth 1 is fixedly connected with a fixing column 8, and the fixing column 8 and the circular reserved groove are clearance-matched, and the bottom of the fixing column 8 passes through the circular reserved groove and extends to the inner side of the square reserved groove, and the outer side of the bottom of the fixing column 8 is fixedly connected with a limiting ring 9, and limiting grooves are opened at both ends of the outer side of the bottom of the fixing column 8, and the limiting grooves are located below the limiting ring 9.

[0044] The installation structure 3 also includes a first spring 10, a first movable disk 11, a connecting column 12, a second movable disk 13 and a guide ring 14.

[0045] The installation structure 3 also includes a fixed shaft 15, a flip plate 16, a first plug plate 17, a first rotating seat 18 and a first connecting rod 19. The two ends of the inner side of the square reserved groove are fixedly connected to the fixed shaft 15, and the outer side of the fixed shaft 15 is rotatably connected to the flip plate 16. The top of the flip plate 16 near one end of the first movable disk 11 is fixedly connected to the first plug plate 17, and the first plug plate 17 and the limiting groove opened at the bottom of the fixed column 8 are plug-in and limited. The bottom of the flip plate 16 near one end of the first movable disk 11 is fixedly connected to the first rotating seat 18, and a first connecting rod 19 is arranged between the two first rotating seats 18 and the two ends of the first movable disk 11, and one end of the first connecting rod 19 is rotatably connected to the first rotating seat 18, and the other end of the first connecting rod 19 is rotatably connected to the first movable disk 11.

[0046] The installation structure 3 also includes a second rotating seat 20, a first rotating plate 21 and a second connecting rod 22. The second rotating seat 20 is fixedly connected to the top of the flip plate 16, and the first rotating plates 21 are rotatably connected at both ends of the inner side of the square reserved groove, and the first rotating plate 21 is located above the second rotating seat 20. A second connecting rod 22 is arranged between the first rotating plate 21 and the second rotating seat 20, and the top of the second connecting rod 22 is rotatably connected to the end of the first rotating plate 21 close to the guide ring 14, and the bottom of the second connecting rod 22 is rotatably connected to the second rotating seat 20.

[0047] The installation structure 3 also includes a second rotating plate 23, a second plug plate 24, a second spring 25, a support plate 26, a third rotating seat 27 and a third connecting rod 28. The second rotating plate 23 is rotatably connected to the top of the inner two ends of the square reserved groove. The second rotating plate 23 is provided with a sliding groove at one end close to the guide ring 14. The second plug plate 24 is fitted with a second spring 25 inside the sliding groove. One end of the second spring 25 is fixedly connected to the second plug plate 24, and the other end of the second spring 25 is fixedly connected to the inner side of the sliding groove. A connection is set up, and the end of the bottom of the second rotating plate 23 away from the guide ring 14 is fixedly connected to the support plate 26, and the support plate 26 supports the second rotating plate 23, and the end of the bottom of the second rotating plate 23 close to the guide ring 14 is fixedly connected to the third rotating seat 27, and a third connecting rod 28 is arranged between the third rotating seat 27 and the first rotating plate 21, and the top of the third connecting rod 28 is rotatably connected to the third rotating seat 27, and the bottom of the third connecting rod 28 is rotatably connected to the end of the first rotating plate 21 away from the guide ring 14.

[0048] Specifically: insert the fixing column 8 into the inner side of the circular reserved groove on the inner side of the implant neck 4. At this time, the bottom of the fixing column 8 will drive the limiting ring 9 to move to the inner side of the square reserved groove on the inner side of the implant neck 4. Then, the bottom of the fixing column 8 will be plugged into the guide ring 14. The inclined setting of the top of the inner circumference of the guide ring 14 can play a guiding effect in the process of inserting the fixing column 8 into the inner side of the guide ring 14, so that the fixing column 8 can be more easily inserted into the inner side of the guide ring 14.

[0049] Through the arrangement of the second plug plate 24 and the second spring 25, when the fixed column 8 drives the limiting ring 9 to move downward, if the second plug plate 24 blocks the descending path of the limiting ring 9, the limiting ring 9 can squeeze the second plug plate 24 to squeeze the second plug plate 24 to the inside of the second rotating plate 23. After the limiting ring 9 passes through the second plug plate 24, the second spring 25 can be used to squeeze the second plug plate 24 again to the inside of the second rotating plate 23, so that it is convenient for the subsequent two second plug plates 24 to limit the top of the limiting ring 9.

[0050] As the fixed column 8 continues to move downward, the second movable plate 13 at the bottom of the guide ring 14 can be squeezed, and then through the connection setting of the connecting column 12, the second movable plate 13 moves downward while the first movable plate 11 is driven to move downward synchronously, and then through the connection effect of the first connecting rods 19 set at both ends of the first movable plate 11, when the first movable plate 11 moves downward, the first connecting rod 19 can be made to move away from the end of the first movable plate 11 to squeeze the bottom of the flip plate 16, so that the flip plate 16 rotates with the fixed axis 15 as the center and is in a vertical state. When the flip plate 16 moves, the first plug plate 17 at the top of the flip plate 16 will move in the direction close to the fixed column 8, and then be inserted into the inner side of the limiting groove on the outer side of the bottom of the fixed column 8. Through the setting of the two first plug plates 17, the fixed column 8 can be limited, so that the installation effect of the tooth 1 can be achieved;

[0051] When the flip plate 16 rotates, the second rotating seat 20 at the top of the flip plate 16 will drive the bottom of the second connecting rod 22 to move in the direction close to the guide ring 14, so that the first rotating plate 21 can be driven to rotate inside the square reserved groove through the connection setting of the second connecting rod 22, and the first rotating plate 21 can be kept in a horizontal state inside the square reserved groove. At the same time, the end of the first rotating plate 21 away from the guide ring 14 will have a downward driving effect on the bottom of the third connecting rod 28, and then through the connection setting of the top of the third connecting rod 28 and the third rotating seat 27, the end of the second rotating plate 23 close to the guide ring 14 can be driven to move downward synchronously. At the same time, through the setting of the support plate 26, a certain supporting effect can be exerted on the second rotating plate 23, so that the second rotating plate 23 can be kept parallel to the second connecting rod 22. At this time, the two second plug plates 24 will have a further limiting effect on the top of the limiting ring 9, so as to further improve the stability of the fixing column 8 on the inner side of the implant neck 4;

[0052] When the fixed column 8 needs to be taken out, the tooth 1 can be moved upward, thereby driving the fixed column 8 to move upward synchronously. At this time, the bottom of the fixed column 8 will cancel the squeezing effect on the first movable plate 11. At this time, the first movable plate 11 can move upward through the elastic deformation of the first spring 10, and drive the two first connecting rods 19 close to the ends of the first movable plate 11 to move upward synchronously. Through the connection setting of the first movable plate 11, while one end of the first movable plate 11 moves upward, it can achieve the effect of making the two sections of the first movable plate 11 drive the first rotating seat 18 at the bottom of the flip plate 16 to move synchronously, so that the flip plate 16 can be flipped with the fixed axis 15 as the center. At this time, the flip plate 16 can drive the two first plugging plates 17 to move in the direction away from the fixed column 8, and cancel the plug-in limiting effect of the limiting groove at the bottom of the fixed column 8;

[0053] At the same time, the top of the flip plate 16 can drive the second rotating seat 20 to move synchronously toward the end away from the fixed column 8. At the same time, through the rotation effect of the flip plate 16, the second rotating seat 20 will also rotate synchronously with the fixed axis 15 as the center, and drive the bottom of the second connecting rod 22. Then, the first rotating plate 21 can be driven to flip synchronously through the connection setting of the second connecting rod 22, and the effect of making the first rotating plate 21 move upward away from the end of the guide ring 14 can be achieved. Then, the bottom of the third connecting rod 28 can be squeezed upward, and through the setting of the third connecting rod 28, the third rotating seat 27 can be driven upward synchronously, so as to achieve the effect of making the second rotating plate 23 flip. At this time, the two second rotating plates 23 will drive the two second plug plates 24 to flip synchronously, and cancel the limiting effect with the top of the limit ring 9, so that the fixed column 8 can be taken out, and the tooth 1 can be replaced or maintained.
