摘要： 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.

摘要： An implant for implantation into bone tissue having an exterior surface includes an elongated body and at least one thread. The elongated body has a distal end portion for being submerged in the bone tissue, a proximal end portion for being located near the exterior surface of the bone tissue, a central axis, and an outer surface. When viewed in cross section, the elongated body has a non-circular cross section. The non-circular cross section includes a plurality of lobes and a plurality of dwells. Each of the plurality of dwells is disposed between adjacent ones of the plurality of lobes. The thread extends radially outward with respect to the central axis from the outer surface of the elongated body between the distal end portion and the proximal end portion. As the implant is screwed into the bone tissue, only the lobes on the elongated body engage the bone tissue. Because no contact exists between the dwells and the bone tissue, the amount of torque required to insert the implant is reduced.

摘要： A support post for use with a dental implant comprising a ceramic portion, a screw, and a metal portion. The ceramic portion is adapted to support a prosthesis thereon. The ceramic portion has a supragingival region for protruding beyond the gingiva and a subgingival end for extending into the gingiva. The ceramic portion has a passageway extending therethrough. According to one embodiment, the passageway narrows to form a shoulder that is made entirely of ceramic. The screw is adapted to engage an internally threaded bore in the implant and be insertable through the passageway. The screw comprises a head and a threaded section. The head of the screw seats entirely on the shoulder. The metal portion comprises a lower section and an upper section extending into the passageway. The metal portion abuts the subgingival end of the ceramic portion. The lower section is adapted to receive and engage the corresponding boss of the dental implant. The metal portion has an opening to provide access to the screw.

摘要： This invention is a post and socket connector (10, 12, 20, 22, 40) having anti-rotational elements (28, 44, 58, 68) near the base of one or both parts for filling selected portions of the space between them, thereby restricting or eliminating relative rotation of the two parts around a common axis.

Each of the plurality of dwells is disposed between adjacent ones of the plurality of lobes. The thread extends radially outward with respect to the central axis from the outer surface of the elongated body between the distal end portion and the proximal end portion. As the implant is screwed into the bone tissue, only the lobes on the elongated body engage the bone tissue. Because no contact exists between the dwells and the bone tissue, the amount of torque required to insert the implant is reduced.
