Description

Technical Field

[0001] The invention relates to the technical field of implant bridges, and in particular to a high-strength titanium alloy bridge for dental implants. Background Art

[0002] A dental implant bridge is a structure used to support artificial teeth. It can be used to connect multiple dental implants and is made of metal or ceramic materials. It is shaped like a bridge and can be fixed on dental implants. By connecting multiple dental implants, it provides better support and stability. The implants connecting the bridge are implanted in the alveolar bone and fused with the femoral tissue to form a stable support structure.

[0003] A Chinese patent with publication number CN112807109A discloses a structural device for solving the problem of personalized full-mouth implant bridges in complex oral cavity. The device has an inclined threaded hole above the nerve in the alveolar bone, so that the opening of the threaded hole is located at the corresponding connection between the alveolar bone and the bridge body, and the nerve is avoided in the threaded hole. The mounting base is then tightened in the threaded hole; ultimately, the bridge body can be stably and firmly installed on the alveolar bone, avoiding the nerve, and the strong bolt can press the bent part into the connecting hole, thereby making the bending base and the mounting base more firmly connected, thereby improving the stability of the bridge body after installation.

[0004] The device fixes the bridge frame by installing two-stage bolts, and the bolts are fixed by threads. After the teeth on the bridge frame are used in occlusion for a long time, they will cause a certain impact on the bolts and the threaded holes, causing a gap between the bolts and the threaded holes, thereby affecting the stability of the bridge frame on the alveolar bone.
