- an implant including a cylindrical body having an externally threaded portion and a hemispherical dome at one end of the cylindrical body, the threaded portion having a plurality of vertically extending grooves extending through the threaded portion but stopping short of the threads toward the other end of the cylindrical body and at least one pair of diametrically opposite depressions for securing the implant in the jawbone, the cylindrical body further having a smooth neck portion at the other end that extends to the threaded portion, a threaded internal bore at the other end with a first diameter, and a cylindrical cavity at the other end abutting said threaded internal bore and having a second diameter larger than the first diameter;
- and
- a dental prosthesis supporting superstructure securable in the cylindrical cavity and including screw means for connecting it with the implant.
