Dental implant

Abstract

Abstract 0 A dental implant [10] is disclosed for rigidly anchoring a prosthesis to a jawbone implant site. The first embodiment of the dental implant comprises a center post [12] having a boss [16] connected to the proximal end [18] thereof. A plurality of fins [14] extend radially outward along the center post along the entire longitudinal length thereof. The boss [16] includes a counterbore [26] and a threaded hole [28] for receiving a support cone [20] having a threaded stud extending therefrom. Alternatively, the boss [16] defines a socket for the reception of a correspondingly shaped plug disposed on the support cone [20]. The base has disposed thereon a circumferential sleeve [17] of ceramic material. The second embodiment of the dental implant [46] comprises a major post [47] having a plurality of elongated fins [50A, 50B] extending radially outward from both sides of the major post [48]. The proximal end of the major post [48] includes a similar counterbore [26] and a threaded hole [28] for receiving the stud of the support cone [20]. One or more minor posts [52] may be connected traversely through the elongated fins [50A, 50B] to add rigidity thereto. In each embodiment, the support cone [20] is configured to receive a prosthesis. The angle of the support cone [20] with respect to the dental implant may be altered by angling the stud [32] with respect to the support cone [20]. A washer [56] is provided for connection between the support cone [20] and the boss [16] or the proximal end of the major post [48] for varying the rotational position of the tilted support cone [20] with respect to the dental implant.
