[0002] Metal implants are oral prostheses made of metal materials and are suitable for patients who need to replace missing teeth. Metal implants have advantages such as high strength, corrosion resistance, and good biocompatibility, making them a new choice in the field of oral restoration. There are many types of metal implants, the most common being titanium alloy implants, pure titanium implants, and stainless steel implants. Each of these implant materials has its own advantages and disadvantages, and doctors will choose the appropriate implant material based on the patient's specific situation.
[0003] After metal implants are fixed to the alveolar bone by threads, if they gradually loosen due to external forces and the threading effect deteriorates, they are prone to falling out, which in turn affects the use of the metal implants.
[0004] Therefore, a metal implant that prevents loosening is needed to solve the above problems. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting a limiting groove and a limiting piece, before installing the root canal, a limiting groove is first machined at a deep position inside the installation groove. After the root canal is installed into the inner side of the installation groove by thread, the adjusting rod located inside the root canal can be rotated. With the adjusting rod and the adjusting hole threaded together, the adjusting rod can be driven to move the cone upward. During the upward movement of the adjusting rod, it contacts the limiting piece inside the sliding groove. During this process, the limiting piece can be pushed outward to drive it to insert into the limiting groove, thereby assisting in limiting the root canal and preventing the root canal from falling out of the inner side of the installation groove, thus strengthening the anti-loosening function of the metal implant after installation.
[0015] With the buckle located in the auxiliary hole on the outer wall of the base, as the base is inserted into the docking groove at the top of the docking platform, the buckle can spring into the slot on the inner wall of the docking groove with the assistance of the second spring. In this way, the pre-installation of the connecting platform can be completed, and the stable installation of the fixing bolt can be assisted in the later stage, thus realizing the positioning assistance function during the installation of the metal implant.
[0016] By setting a sealing groove and a sealing ring, the sealing groove is located on the top surface of the docking platform. In use, the sealing ring is placed in the sealing groove. When the base on the bottom side of the docking platform is inserted into the docking groove at the top of the docking platform for installation and connection, the sealing ring can be compressed. During the deformation of the sealing ring, it can help to seal the connection, thus enhancing the sealing effect of the metal implant connection. Attached Figure Description

[0029] Working principle: In use, a mounting groove 2 is first machined in the alveolar bone 1. Then, a ring-shaped limiting groove 12 is machined deep inside the mounting groove 2. During later installation, the root canal 3 is threaded into the mounting groove 2. After installation, the adjusting rod 18 located inside the root canal 3 can be rotated with the help of a tool, thereby driving the bottom cone 19 to move upward. During this process, it contacts the limiting plates 14 around the perimeter. Through the curvature, the limiting plates 14 are pushed outward along the sliding groove 13 and locked into the inside of the limiting groove 12. They cooperate to further prevent the root canal 3 from separating from the mounting groove 2. After the root canal 3 is installed, the tooth body 8 can be installed. Before the connecting platform 7 and the tooth body 8 are installed, the sealing plate is first installed. The sealing ring 26 is placed in the sealing groove 25 on the top surface of the docking platform 4. When the connecting platform 7 docks with the docking platform 4, the sealing ring 26 can be compressed. The sealing ring 26 can help seal the connection and prevent foreign objects from entering. When the base 6 at the bottom of the connecting platform 7 docks with the docking groove 5 at the top of the docking platform 4, the buckle 22 on the outer wall of the base 6 can be inserted into the second spring 23. This helps to position the connecting platform 7 and the tooth 8 on the docking platform 4. Then, the fixing bolt 10 can be inserted into the fixing hole 11 through the internal hole of the tooth 8 and the fixing bolt 10 can be tightened to complete the installation and fixing operation of the tooth 8. After that, the internal hole of the tooth 8 can be repaired.
