Abstract: An endosseous dental implant system having an implant body and an abutment. The implant body has a tapered cylindrical surface near its top end and an internally threaded or unthreaded passage extending into the implant body through an opening at the top of the implant. The abutment has an internal passage for receiving a fastener or, alternatively has a fastener as part of the abutment.The fastener threads into the implant body so that a tapered cylindrical cavity in the abutment mates with a matching tapered cylindrical surface of the implant to form an anti-rotational and locking junction with the implant when fastened by a screw or fastener. In addition to the anti-rotational and locking junction formed by the mating of external tapered cylindrical surface and internal tapered cylindrical surface, the dental implant system may also include an implant body having a multi-sided projection. In this embodiment, the abutment has a cavity for receiving the projection. The cavity and projection forms an additional anti-rotational junction between the implant body and the abutment.

Abstract: A single stage dental implant for implantation in living jawbone having overlying gingiva comprises a generally cylindrical body section having an exterior surface for confronting the jawbone and a head section attached to the body section for extending through the overlying gingiva when the body section is confronting the jawbone. The head section has an end portion which is generally near an outer layer of the gingiva. The implant further includes a bore within the head section extending to an opening at the end portion of the head section. The bore is defined by first, second, and third walls. The first wall has internal threads. The second wall has a larger diameter than the first surface and is substantially cylindrical. The second wall extends from the first wall toward the end portion. The third wall extends from the second wall to the opening and flares toward the opening to a diameter that is wider than a diameter of the second wall. The implant is delivered to the site in the patient's mouth with a carrier that is expanded into the second wall of the bore thereby developing a tight engagement capable of withstanding the insertion torque. The implant can be fitted with posts which extend above the upper portion of the implant. The post can be fitted with gingival forming components and temporary posts.

Abstract: A dental implant system comprising a fixture (301; 401; 501) for implantation in bone tissue (312, 314; 512, 514) of the maxilla or mandible by displacement thereof in a forward direction, the fixture having a forward end, a rearward end (330; 430; 530), and an outer surface (305; 405; 505) which extends between the forward and rearward ends and which forwardly of a predetermined position (307; 407; 507) on the outer surface is adapted for interlocking with bone tissue of the maxilla or mandible; and a superstructure (402) for mounting on the fixture, the superstructure having a forward end for interfacing with the rearward end of the fixture, the forward end of the superstructure and the rearward end of the fixture each presenting interfacing surfaces for interfacing with one another. The rearward end of the fixture and the forward end of the superstructure are so contstructed and dimensioned that a predetermined interfacing surface of the superstructure (423) is able to interface in the forward direction with a predetermined interfacing surface of the fixture (311; 409; 525) which is at a level which is disposed forwardly of the predetermined position on the outer surface. A more favourable stress distribution in the bone tissue adjacent the fixture results.

Abstract: The invention relates to an enossal tooth implant comprising a rotationally symmetrical lower section, a head and a threaded bore hole axially extending from the head to accommodate a fastening screw to retain a crown of the tooth. The head is tapered on both sides, formed by bevels extending on both sides of the threaded bore hole across the row of teeth. The bevels form cutting lines extending from the edges of one of the front faces of the head in conjunction with the periphery of the head, said cutting lines having a variable height and matching the natural shape of the upper edge of the jaw bone. A contact member joined to the crown of the tooth is adapted to the tapering on the upper end of the head of the implant and configured to match the crown of the tooth. The two-sided tapering can be asymmetrical in design for improved matching to the anatomy of the jaw bone and the soft tissue located above. The special shape of the implant enables it to compensate for the differences in height between the tongue, the mouth and the approximate height of the bone, thereby emulating the natural upper edge of the jaw bone.

Abstract: The invention relates to a rotationally symmetrical anchoring element for anchoring in bone tissue, for example permanent anchoring of artificial teeth and dental bridges in the jaw bone. The anchoring element is made of a biocompatible material and has a circumferential surface which includes a lower portion (6) intended to be incorporated with bone tissue, and an upper portion (9) which, following implantation, is located outside the bone tissue for the purpose of attachment of a spacer piece (12) or a prosthetic structure. The said upper portion (9) includes a smooth (unthreaded) conical portion (9) whose diameter increases in the direction away from the upper end surface (gable surface) (7) of the element. The conical portion (9) forms a bearing surface for the spacer piece (12) or the prosthetic structure.
