| description | The utility model relates to an annular cutter for positioning gingivae applied to tooth implantation. The annular cutter for positioning gingivae applied to the tooth implantation structurally comprises a positioning needle and an annular cutter which sleeves the positioning needle, wherein the positioning needle is characterized in that a cylindrical handle with the diameter being larger than that of a needle rod is arranged at the upper end of a cylindrical straight handle needle rod, a conical needle head is arranged at the lower end of the needle rod, and a needle tip part of the needle head is arranged on an axial center line of the needle rod; the annular cutter is characterized in that a prismatic rotary handle extending out of the outer side wall of the needle cylinder is arranged at the upper end of a cylindrical needle cylinder, and a circular cutting edge with the conical degree is formed in the lower end of the needle cylinder. The annular cutter for positioning gingivae is capable of annularly cutting the gingival tissue in the tooth implantation process; the annular cutter is used for annularly cutting the gingivae on the surface of an implantation body in the two-stage operation of the tooth implantation, so that a coverage screw of the implantation body is exposed, and a gingivae healing abutment is replaced. By virtue of the annular cutter for positioning gingivae applied to the tooth implantation, the surgical operations can be simplified; the surgical time is shortened; the surgical efficiency is improved; the infection risk is reduced. |
