Abstract

The oral implant is in the shape of a cylinder with a flat proximal end and a rounded distal end. Projecting members are formed on the cylindrical surface that taper from the proximal end of the cylindrical body toward the distal end thereof. The projecting members are radially spaced, and in one embodiment have flutes formed on the tapered surface. A lateral through-hole is provided at the distal end of the cylindrical body. The proximal end includes a hexagonal-shaped recess for reception of a twisting tool. After the twisting tool is removed the hexagonal recess receives a dental prosthesis. Another embodiment of the oral implant includes radially spaced ridges that are longitudinally aligned with projecting members on quadrants of the cylindrical surface. Either embodiment of the implant member is installed by press-fitting the implant into a hole in the jawbone and then twisting the implant a predetermined amount to permit the projecting members and the ridges to breach into the bone thereby forming undercuts in the bone that rigidly lock the implant in position.
