Positioning gingival circumcision for dental implants

Abstract

The invention relates to a positing gingival ring cutting device for dental implantation. The ring cutting device structurally comprises a positioning pin and a ring cutter sleeving the positioning needle; a ring-shaped handle of which the diameter is larger than that of a needle rod is arranged at the upper end of the cylindrical straight shank needle rod so as to form the positioning needle; a conical needle head is arranged at the lower end of the needle rod; the needle tip of the needle head is positioned at the axial center line of the needle rod; a prismatic rotary handle extending out from the outer side wall of a needle cylinder is arranged at the upper end of the cylindrical cutter cylinder so as to form the ring cutter, and the lower end of the needle cylinder is a tapered circular cutting edge. The ring cutting device provided by the invention can cut gingival tissues circularly in a dental implantation process, is used in a second phase of dental implantation surgery, can cut gingivae on the surface of an implant in a ring manner to expose cover screws of the implant, so as to replace a gingival healing abutment. By adoption of the ring cutting device, surgical procedures are simplified, the surgical time is shortened, the surgical efficiency is improved, and the risk of infection is reduced.

Description

technical field

[0001] The invention relates to a dental operation appliance, in particular to a positioning gingival circumcision device for dental implantation. Background technique

[0002] Dental implantology is an independent new branch developed in recent years, mainly including implant surgery, implant restoration, implant materials, implant mechanics and implant biology. The "osseointegration" founded by Professor Branemark in Switzerland in the 1950s and 1960s laid the theoretical foundation for modern dental implantology. The most promising sub-discipline, oral implant restoration has become a common restoration method for dentition defects and edentulousness.

[0003] With the continuous maturity of dental implant technology and the continuous improvement of the success rate of dental implants, especially dental implants have many advantages, more and more people accept dental implants after tooth loss to restore dentition and chewing function.
