<p>The piece, designed for dental osseointegration implants, is made of a biocompatible matenal such as titanium and consists of a body (1, 1') of a generally cylindrical shape, with a smooth segment (2, 2') with its free end (4, 4') round and a threaded cylindrical segment (3, 3') ending with a short cylindrical segment (5, 5') on which the corresponding polygonal head (7,7') of the implant is established. The entire length defined by both segments (2, 2') (3, 3') is provided with double-ruled grooves (6, 6') equidistant from each other. The piece constitutes a mixed implant which may be placed in the patient by a simple surgical technique without perforating the sinus mucous. <IMAGE></p> |
