ABSTRACT:
A threaded pin for implantation use in dentistry, comprising a cylindrical stem with an external thread near one end, a head for application of a tool at the other end and a point at the opposite end near the thread. The point has the same shape as the point of the milling cutter used to make the elongated hole in the bone in which the implantation is to be make. The dimensions of the thread are relatively small in comparison with the diameter of the stem to avoid exerting excessive pressure and cause damage to the bone as the pin is screwed thereinto.
