A self-tapping dental implant (10) comprises a generally cylindrical body (12) with a threaded outer surface for securing the implant to the walls of a preformed hole in a jaw bone. The cylindrical body has a plurality of longitudinal recesses (22, 24, 26, 28) formed in the threaded surface at one end, and extends longitudinally through a plurality of turns of the thread to form a self-tapping cutting edge (32, 34, 36, 38) at each interruption of the thread by one of the recesses. Each thread segment extends between a pair of adjacent recesses and diminishes in radius between the leading and trailing ends of the thread end.
