Abstract

Abstract A self-threading pin (1) for the implantation of dental prosthesis is formed at one end with a drill bit (2). The screw threaded portion (3) of the pin (1) is provided with longitudinal flutes (5) for discharging the drilled material, departing from the rear end of the discharge grooves (4) of the drill bit (2) and extending along the whole length of the screw threaded portion (3) of the pin (1). The head (6) of the pin has a polygonal cross sectional shape for driving the pin by means of a tool.
