Problems solved by technology

[0003] The existing method of connecting implants with threads is cumbersome during the operation process. It needs to use drills with gradually increasing diameters to operate multiple times to generate threaded holes suitable for implant implantation. At the same time, the sharp corners of the threads are prone to stress Concentration, there is a hidden danger of fracture and failure of the implant

Abstract

The invention relates to the technical field of medical instruments, and discloses an internal expansion type artificial tooth root which comprises an implant, an abutment and a connecting device, the connecting device comprises a sleeve, an expansion part and a screw, the implant is provided with a mounting hole, the expansion part and the sleeve are sequentially assembled in the mounting hole, the abutment is assembled in the sleeve, the abutment is provided with a first through hole, the sleeve is provided with a second through hole, the expansion part is provided with an internal thread matched with the screw, the screw penetrates through the first through hole and the second through hole and is in threaded connection with the expansion part, and a plurality of elastic pieces are further arranged at the bottom of the sleeve and can expand outwards under supporting of the expansion part. Compared with the prior art, the internal expansion type artificial tooth root structure is simple and reliable and good in connecting effect.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an internally expanding artificial tooth root. Background technique [0002] Oral implants are components that are implanted in bone tissue to support the upper tooth restoration to withstand masticatory forces. In the case of dentition defects, implant implantation can be used to obtain artificial tooth roots that support the restoration. The degree of integration between the implant and the alveolar bone is an important indicator for judging the effect of the implant surgery. The degree of integration is mainly reflected in the growth of bone tissue on the surface of the implant and the stability of the implant itself in the alveolar bone. In the prior art, the implant is mainly connected to the alveolar bone through the external thread. During the implant operation, a drill bit is required to tap the internal thread on the alveolar bone. The connection between the ...
