ABSTRACT:
This invention consists of three main parts and a shock-absorbing resilient member. The first main part is a self-drilling implant. The self-drilling implant is tubular in design, having a hollow basket that saves some of the bone granulate from the osteotomy. The bone granulate encourages the formation of a blood clot, helps to immobilize the implant and provides an absorbable substance to precipitate recalcification. The second part is a tissue extension that screws into the implant. The tissue extension has a socket which receives the third element, i.e., the keeper. Two alternative keeper designs, each with its own type of shock-absorbing member, are disclosed. Each keeper embodiment has a bi-frustum principle shape and a longitudinal central shaft. Various dental prosthesis may be attached to the keeper.
