[0006] Optionally, the cross sections of the sliding block and the sliding groove are T-shaped, recesses are formed in the outer walls of the multiple inner support plates, and the number of recesses is multiple.

[0007] Optionally, a positioning block is fixedly connected to the inner wall of each of the multiple inner support plates, a positioning groove is formed in the outer wall of the implant body, and the number of positioning grooves is multiple, and the positioning block is arranged in the positioning groove.

[0008] Optionally, the outer wall of the pressure plate is provided with limiting blocks, and the number of limiting blocks is multiple. The top of the implant body is provided with limiting grooves, and the number of limiting grooves is multiple. The multiple limiting blocks are respectively located inside the multiple limiting grooves.

[0009] Optionally, the top of the inner wall of the implant body is provided with an internal thread, the outer wall of the implant body is provided with a positioning hole, the top inner wall of the implant body is threadedly connected to a base, and the top of the base is fixedly connected to a base.

[0010] Optionally, the plurality of positioning holes are located at the top edge of the implant body, the plurality of positioning grooves are located in the middle of the outer wall of the implant body, and the positioning grooves are located in the middle of the two telescopic grooves in the same group.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. When installing the implant body, place the implant body into the pre-drilled hole in the alveolar bone, ensuring the positioning hole on the outer wall of the implant body is facing forward. Then, insert a tool into the positioning hole to prevent displacement of the implant body. Next, rotate and screw the abutment base into the top of the implant body. As the abutment base enters the top of the implant body, it presses down the pressure plate and pressure rod, causing multiple connecting rods and sliders connected to the outer wall of the pressure rod to move downwards. Since the sliders are located in the grooves in the telescopic blocks, the multiple telescopic blocks move outwards along the telescopic grooves, thereby causing multiple inner support plates to move outwards synchronously. Simultaneously, due to the multiple inner support plates... The outer walls of the implant are grooved, allowing the inner support plates to extend and press tightly against the holes in the alveolar bone. The grooves on the outer walls of the inner support plates increase friction between them and the black holes in the alveolar bone as they extend outwards, preventing the implant from easily falling out. At this time, the springs are compressed, thus fixing the abutment and the implant body within the holes in the alveolar bone. Similarly, when maintenance or replacement of the implant body is needed, the springs rebound after the abutment base separates from the top of the implant body, causing the multiple pressure plates to retract inwards. This makes the implant body easy to assemble and disassemble quickly and conveniently, improving the success rate and stability of the surgery.

[0013] 2. The inner walls of the multiple pressure plates of this utility model are provided with positioning blocks, which makes the movement of the multiple pressure plates more stable when they extend outward and retract inward. This makes the outward extension force of the multiple pressure plates consistent, ensuring that the multiple pressure plates are fixed in the holes opened in the alveolar bone, extending the service life of the implant body, and reducing the probability of secondary surgery or postoperative discomfort caused by loosening of the implant body.
