ABSTRACT:
A dental implant is adapted to be installed in a bore formed in jaw bone tissue for retaining a dental prosthesis. The implant comprises a generally cylindrical body defining a longitudinal axis and including an outer periphery. The body is opened at a front end thereof and includes a front cylindrical cavity for receiving a cylindrical bore core. A plurality of through holes is formed in the body and communicates with the front cavity to accommodate the growth of bone tissue therethrough. The body is opened at a rear end thereof and includes a rear cavity communicating with the open rear end for receiving a prosthesis-attachment. The outer periphery of the body can be cylindrically smooth or may include a plurality of longitudinally spaced, circumferentially disposed ribs. There are thus defined on the outer periphery a plurality of circumferentially continuous surface regions adapted to engage the wall of the bore in the bone to resist the flow of blood past the implant. This, in turn, promotes blood clotting and the regeneration and regrowth of bone tissue.
