Description

Technical Field

[0001] This invention belongs to the field of dental implant technology, specifically a multi-threaded dental implant. Background Technology

[0002] Multi-threaded dental implants are typically made of materials such as medical-grade titanium alloys, and their surfaces are decorated with multiple fine threads. When implanted into the alveolar bone, these threads increase the contact area with bone tissue, improve initial stability, promote osseointegration, and better distribute chewing forces. They are suitable for various tooth loss restorations and provide reliable support for dentures.

[0003] Existing multi-threaded dental implants are divided into upper implants and lower implants, which are usually connected together by threads. The upper implant is also connected to the abutment by threads, which makes the installation and disassembly of the three components inconvenient. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-threaded dental implant that can be installed by simply screwing the abutment onto the upper implant. Disassembly is simple and convenient, requiring only the abutment to be unscrewed to separate the three components.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A multi-threaded dental implant is provided, including an upper implant. A connecting disc is fixedly connected to the lower surface of the upper implant. An installation block is fixedly connected to the lower surface of the connecting disc. The sidewall of the installation block has four installation grooves. A movable block is disposed inside each installation groove. An inclined groove is disposed inside the movable block. A movable groove is disposed on the inner wall of the inclined groove. A connecting groove is disposed on the upper surface of the upper implant. A spring is fixedly connected to the bottom of the connecting groove. A movable disc is fixedly connected to one end of the spring. A movable plate is fixedly connected to the lower surface of the movable disc. Four movable plates are disposed. A pin is fixedly connected to the end of each movable plate away from the movable disc. The pin is located inside the inclined groove. A lower implant is disposed below the upper implant. A stabilizing groove is disposed inside the lower implant. The number of stabilizing grooves is four.

[0006] Optionally, the upper surface of the implant has a first groove, and the connecting disc is located inside the first groove.

[0007] Optionally, a second groove is provided at the bottom of the first groove, the second groove is connected to the stabilizing groove, and the mounting block is located inside the second groove.

[0008] Optionally, a positioning groove is provided at the bottom of the second groove, and a positioning block is fixedly connected to the lower surface of the mounting block, the positioning block being located inside the positioning groove.

[0009] Optionally, a first sealing groove is formed on the inner surface of the first groove, and a first sealing ring is fixedly connected to the inner surface of the first sealing groove.

[0010] Optionally, a second sealing groove is provided at the bottom of the connecting groove, a second sealing ring is fixedly connected to the inner surface of the second sealing groove, and a third sealing groove is provided on the lower surface of the movable disk.

[0011] Optionally, the inner surface of the connecting groove is provided with a threaded groove, the outer surface of the upper implant is fixedly connected with a first threaded ring, and the outer surface of the lower implant is fixedly connected with a second threaded ring.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This invention comprises an upper implant, a moving block, an inclined groove, a moving disc, a lower implant, a moving plate, a pin, a stabilizing groove, a positioning groove, and a positioning block. When connecting the upper and lower implants, the positioning block is first aligned with the positioning groove, allowing the upper and lower implants to slowly approach each other until they are fully seated within the positioning groove. The abutment is then screwed onto the upper implant via the threaded groove. As the abutment is screwed down, it compresses the moving disc, causing it to move downwards, which in turn moves the moving plate and pin downwards. Due to the inclined groove, adjacent moving blocks are moved away from each other, allowing the moving blocks to enter the stabilizing groove. The moving disc stops moving downwards when the abutment can no longer be screwed down. At this point, the upper and lower implants and the abutment are connected. Separation is achieved simply by unscrewing the abutment. This invention simplifies the installation of the upper and lower implants by screwing the abutment onto the upper implant, and disassembly is achieved by unscrewing the abutment. The operation is simple and convenient. Attached Figure Description

[0028] Reference Figure 1-8The present invention will now be described. A multi-threaded dental implant includes an upper implant 1. A connecting disc 2 is fixedly connected to the lower surface of the upper implant 1. An installation block 3 is fixedly connected to the lower surface of the connecting disc 2. The side wall of the installation block 3 has four installation grooves 4. A movable block 5 is disposed inside each installation groove 4. An inclined groove 6 is formed inside the movable block 5. A movable groove 7 is formed on the inner wall of the inclined groove 6. A connecting groove 8 is formed on the upper surface of the upper implant 1. A spring 9 is fixedly connected to the bottom of the connecting groove 8. One end of the spring 9 is fixedly connected to a movable disc 10. A movable plate 11 is fixedly connected to the lower surface of the movable disc 10. The number of movable plates 11... There are four implants. A pin 12 is fixedly connected to the end of the movable plate 11 furthest from the movable disk 10. The pin 12 is located inside the inclined groove 6. A lower implant 13 is located below the upper implant 1. The lower implant 13 has four stabilizing grooves 14 inside. When connecting the upper implant 1 and the lower implant 13, first align the positioning block 18 with the positioning groove 17, so that the upper implant 1 and the lower implant 13 slowly approach each other until they are in contact and the positioning block 18 is completely inside the positioning groove 17. Then, the abutment is screwed onto the threaded groove 24. On the upper implant 1, the abutment moves downward during the twisting process, which squeezes the moving disc 10 and causes it to move downward, thereby causing the moving plate 11 and the pin 12 to move downward. Due to the presence of the inclined groove 6, the adjacent moving blocks 5 will move away from each other, causing the moving blocks 5 to enter the interior of the stabilizing groove 14, until the abutment can no longer be twisted and the moving disc 10 stops moving downward. At this time, the upper implant 1, the lower implant 13 and the abutment are connected together. To separate them, simply unscrew the abutment, which is more convenient. The upper surface of the lower implant 13 has a first groove 15, and the connecting disc 2 is located inside the first groove 15. To provide a placement space for the connecting plate 2, a second groove 16 is provided at the bottom inner part of the first groove 15. The second groove 16 is connected to the stabilizing groove 14. The mounting block 3 is located inside the second groove 16, which provides a placement space for the mounting block 3. A positioning groove 17 is provided at the bottom inner part of the second groove 16. A positioning block 18 is fixedly connected to the lower surface of the mounting block 3. The positioning block 18 is located inside the positioning groove 17. The positioning groove 17 and the positioning block 18 are both triangular in shape and the same size. The positioning groove 17 and the positioning block 18 can prevent the upper implant 1 and the lower implant 13 from rotating after they are installed together.

[0029] The present invention provides a multi-threaded dental implant, which, compared with the prior art, only requires screwing the abutment onto the upper implant 1 to complete the installation of the upper implant 1, the lower implant 13 and the abutment. Disassembly only requires unscrewing the abutment to separate the three parts, making the operation simple and convenient.

[0030] Please refer to another embodiment of this utility model as well. Figures 1 to 8The inner surface of the first groove 15 is provided with a first sealing groove 19, and a first sealing ring 20 is fixedly connected to the inner surface of the first sealing groove 19. The first sealing ring 20 can prevent blood from entering the stabilizing groove 14 and the second groove 16 through the gap. The bottom of the connecting groove 8 is provided with a second sealing groove 21, and a second sealing ring 22 is fixedly connected to the inner surface of the second sealing groove 21. The lower surface of the moving disk 10 is provided with a third sealing groove 23. After the moving disk 10 moves down, the third sealing groove 23 will contact the second sealing ring 22, thereby preventing blood from flowing along the connecting groove 8 into the spring 9 and contaminating the spring 9.

[0031] In another embodiment of this utility model, please refer to Figures 1 to 8 The inner surface of the connecting groove 8 is provided with a threaded groove 24. The outer surface of the upper implant 1 is fixedly connected with a first threaded ring 25, and the outer surface of the lower implant 13 is fixedly connected with a second threaded ring 26. The first threaded ring 25 and the second threaded ring 26 cooperate with each other so that the threads can fully contact the bone tissue during the implantation of the implant into the alveolar bone.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
