ABSTRACT:
A dental implant is disclosed for rigidly anchoring a prosthesis to a jawbone implant site. The first embodiment of the dental implant comprises a center post having a boss connected to the proximal end thereof. A plurality of fins extend radially outward along the center post along the entire longitudinal length thereof. The boss includes a counterbore and a threaded hole for receiving a support cone having a threaded stud extending therefrom. Alternatively, the boss defines a socket for the reception of a correspondingly shaped plug disposed on the support cone. The base has disposed thereon a circumferential sleeve of ceramic material. The second embodiment of the dental implant comprises a major post having a plurality of elongated fins extending radially outward from both sides of the major post. The proximal end of the major post includes a similar counterbore and a threaded hole for receiving the stud of the support cone. One or more minor posts may be connected traversely through the elongated fins to add rigidity thereto. In each embodiment, the support cone is configured to receive a prosthesis. The angle of the support cone with respect to the dental implant may be altered by angling the stud with respect to the support cone. A washer is provided for connection between the support cone and the boss or the proximal end of the major post for varying the rotational position of the tilted support cone with respect to the dental implant.
