Abstract: A dental attachment assembly has an abutment portion at the proximal end of a one-piece dental implant (an “abutment portion”), or is an abutment for attachment to a dental implant or to a bar joining two or more dental implants, and a two-part assembly including a metal cap for placement in/attachment to a dental appliance. The cap includes a flanged skirt that projects from the top surface of the cap. A second part, a plastic insert, snaps firmly inside the cap.

Abstract: A one-piece, screw-receiving, externally-threaded endosseous dental implant includes a body portion with external threading and, at its proximal end, an unthreaded, cylindrical portion including a retentive groove for engaging a complementary transfer component or comfort cap; a one- or two-piece screw-receiving implant abutment for attachment to a one or two-piece implant, including a retentive groove for engaging a complementary transfer component or comfort cap; and a fixture mount for insertion in a one-piece implant, that can be sectioned with the distal end used to extend the implant height.

Abstract: Endosseous dental implants tapered over at least part of their length, include two separate portions, a shorter proximal region with half the distance and half the depth between adjacent peaks of multiple lead threads as the longer distal region which has half the number of multiple lead threads as in the proximal region.

Abstract: An endosseous dental implants include a flared implant extender with an internal passage and with an unthreaded external surface that tapers downwardly from the proximal end of the extender toward its distal end that has a size and shape appropriate to cover the top surface of the implant.

Abstract: Endosseous dental implants include an at least partly, externally-threaded body portion, an internal cavity or shaft with an opening to the cavity or shaft at the top surface of the implant, and, in the internal cavity or shaft, a threaded portion, and a two part interlock chamber contiguous to said threaded portion including multi-lobed surfaces in a first part, and a plurality of lobes, slots or grooves in a second part.

Abstract: Endosseous, root-formed dental implants for insertion into an opening of the jawbone of a patient include a body with an internally-threaded shaft extending from the top surface of the implant into the body, a flared implant extender with an internal longitudinal passage, having an unthreaded external surface tapering downwardly from the proximal end of the extender toward its distal end of size and shape appropriate to cover the top surface of the implant, and a healing screw with a head joined to a threaded shank, said length of threaded shank of the healing screw and length of internally-threaded shaft of the implant, of adequate lengths to permit engagement of the internal threads of the implant when the head of the healing screw is seated on the top of the extender or on top of the implant, in the absence of the extender, covering the proximal opening into the longitudinal passage of the extender or the internal shaft of the implant.

Abstract: An externally-threaded, one-piece endosseous dental implant including an angled, proximal portion that functions as an abutment for cemented restorations.

Abstract: A one-piece, screw-receiving, externally-threaded endosseous dental implant includes a body portion with external threading and, at its proximal end, an unthreaded, cylindrical portion including a retentive groove for engaging a complementary transfer component or comfort cap; a one- or two-piece screw-receiving implant abutment for attachment to a one or two-piece implant, including a retentive groove for engaging a complementary transfer component or comfort cap; and a fixture mount for insertion in a one-piece implant, that can be sectioned with the distal end used to extend the implant height.

Abstract: Endosseous dental implants include external threads, and, within an internal passage inside the body of the implant, a lead-in bevel, 8-sided abutment-engaging surfaces, distally positioned 6-sided wrench-engaging surfaces, and internal threading distal to both the 8-sided and 6-sided surfaces, and fixture mounts and abutments including male projections to engage the 6-sided wrench-engaging surfaces inside the implants.

Abstract: Endosseous dental implants tapered over at least part of their length, include two separate portions, a shorter proximal region with half the distance and half the depth between adjacent peaks of multiple lead threads as the longer distal region which has half the number of multiple lead threads as in the proximal region.

Abstract: A multi-part abutment for use with an endosseous dental implant includes a first part with a tapered portion at its proximal end adapted to accept a dental restoration and an optional transfer cap, a distally-positioned external multi-lobed or other wrench-engaging portion, an inwardly-projecting non-circular bevel extending partly or entirely around the first part, connecting the proximal and wrench-engaging portions. The first part has an internal through passage with an internal projection or threads or both. The second abutment part, a screw, has a proximal region to engage the internal projection(s) or threads or both of the first part, and a threaded shank to engage internal threads in an endosseous dental implant.

Abstract: Externally-threaded endosseous dental implants that include the structure of an implant body and an abutment/head also include, between the head portion and the body portion, a beveled shoulder portion that extends downwardly and outwardly from the head portion.

Abstract: Endosseous dental implants include an at least partly, externally-threaded body portion, an internal cavity or shaft with an opening to the cavity or shaft at the top surface of the implant, and, in the internal cavity or shaft, a threaded portion, and a two part interlock chamber contiguous to said threaded portion including multi-lobed surfaces in a first part, and a plurality of lobes, slots or grooves in a second part.
