ABSTRACT:
A dental implant is adapted to be installed in a predrilled 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 open at a front end thereof and includes a front cylindrical cavity for receiving a cylindrical bone 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 open 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 includes a plurality of longitudinally spaced, reservoir-defining structures, each of which includes a recessed surface facing toward one of the longitudinal ends of the implant and arranged to store blood adjacent the surrounding bone to promote the growth of new bone tissue.
