摘要:
A dental component attaches to an implant implanted in living jawbone having overlying gingiva. The implant has an apical end embedded within the jawbone and a gingival end near an interface of the gingiva and the jawbone. The dental component comprises a body having a lower region, a gingival region, and a supragingival region. The lower region has an end surface to engage the gingival end of the implant. The gingival region extends through the gingiva and has an outer surface for forming and maintaining an aperture in the gingiva that exposes the gingival end of the implant. The supragingival region has a top surface projecting above the gingiva. The dental component includes first means for receiving a healing element and second means for receiving an impression element. The healing element includes means for fastening the body to the implant so as to allow the gingiva to heal around the body for an extended period of time thereby forming the aperture. The impression element includes an upper segment extending above the supragingival region for receiving impression material and means for securing the body to the implant. Consequently, the dental component serves as part of both a gingival healing component and an impression component.

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.

The present invention relates to a new dental implant (10) that includes a generally cylindrical section (14) and a tapered section (18). The implant has a thread (20) making a plurality of turns around the exterior surface. The implant (10) is installed into a bore that includes a generally cylindrical portion and a tapered portion. The dimensions of the cylindrical section (14) and the tapered section (18) of the implant are at least the dimensions of the generally cylindrical portion and the tapered portion of the bore, respectively. The bore is preferably shaped by a shaping drill that has a profile that generally mimics the profile of the implant. The female threads are preferably developed through a compression tap or a series of compression taps that cause the bone tissue defining the female threads to have increased density.

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.

A self-tapping dental implant (10) comprises a generally cylindrical body (12) with a threaded outer surface for securing the implant to the walls of a preformed hole in a jaw bone. The cylindrical body has a plurality of longitudinal recesses (22, 24, 26, 28) formed in the threaded surface at one end, and extends longitudinally through a plurality of turns of the thread to form a self-tapping cutting edge (32, 34, 36, 38) at each interruption of the thread by one of the recesses. Each thread segment extends between a pair of adjacent recesses and diminishes in radius between the leading and trailing ends of the thread end.
