Abstract: One-piece, root-form, endosseous dental implants include, in a single implant, a body portion for insertion into an opening in the jawbone of a patient, a neck portion above the body portion, and an abutment portion above the neck portion. The abutment portion includes a peripheral shoulder and an opening into an internally-threaded shaft. The implant may also include internal or external wrench-engaging surfaces.

Abstract: Endosseous dental implants having generally cylindrical-shaped or tapering bodies and, in some cases, external threads or ribs over a substantial portion of their external surface, may include internal or external wrench-engaging surfaces at the proximal end portion and include, below a relatively smooth proximal end or neck portion, an external transition zone with a rougher surface, and a body portion having greater surface roughness than the transition zone, or, on the body portion, an HA or TPS coating, to promote attachment of the implant to bone tissue when the implant is placed in a passage formed in bone tissue to receive the implant.

Abstract: A healing collar for use with an endosseous dental implant that has an internal-threaded passage and at the top has a multi-sided male projection includes a cylindrical-shaped external surface, a first cavity at one end that has the same number of sides as the male projection atop the implant and a size and shape adapted to fit frictionally or non-frictionally over the male projection. At the other end of the healing collar is an opening leading to a second internal cavity having a plurality of sides adapted to engage a tool suitable for inserting an implant, joined to the healing collar, into a passage formed in the jawbone of a patient formed to receive the implant. Between the first and second internal cavities is an inwardly-projecting flange that has upper and lower annular surfaces for engaging the head a fixation screw, and the top surface of the implant, respectively.

Abstract: A twist-bladed dental drill with an enhanced cutting tip for preparing surgical sites for endosseous implants includes a central, axially-extending internal passageway for carrying fluid through the shank of the drill to the outer surfaces of the drill.

Abstract: Endosseous dental implants having generally cylindrical-shaped bodies and self-tapping threads at the distal end and, in some case, external threads over a substantial portion of their external surface, include internal or external wrench-engaging surfaces at the proximal end portion and, between the relatively smooth distal and proximal end portions, an external middle region having greater surface roughness than the proximal or distal ends, or a coating, to promote attachment of the implant to bone tissue when the implant is placed in a generally-cylindrical passage formed in bone tissue to receive the implant.

Abstract: An endosseous dental implant system includes a dental implant having a multi-sided projection at its top end and an internally threaded or unthreaded passage extending into the body of the implant through an opening in the projection at the top of the implant, and an abutment having an internal passage for receiving a fastener that passes through the internal passage of the abutment, and threads into the internal passage inside the implant. The abutment has a multi-sided internal cavity at its bottom end with each of the cavity sides perpendicular to the longitudinal axis of the abutment so that the cavity, when seated over the projection at the top of the implant, forms an anti-rotational, interlocking junction with the implant.

Abstract: An abutment adapted for use with a dental implant includes a hollow tubular member of a size and shape adapted for use with an abutment or insert, and includes irregularities on its exterior surface that are adapted for engaging metals cast thereto. The tubular member has, at one end, a retention member for engaging a complementary retention member on the dental implant. The tubular member includes an internal passage adapted to receive a fastener for engaging a complementary fastener in the implant. The tubular member also includes an exterior sidewall portion adapted to form a positional transfer impression of the abutment in a dental cast.

Abstract: A multi-part abutment adapted for use with dental implants such as cylindrical-shaped endosseous dental implants having an internal opening or passage with an internal, non-circular shape at the top includes part one that sealingly engages the opening or passage in the top of the implant at the bottom end of part one, and engages another abutment part, part two, at the top end of part one through a multi-sided projection. Part two has at its bottom end a multi-sided cavity that interdigitates with the projection from part one so that part two can be seated in a plurality of positions atop part one. At the top end of part two is a prosthesis-engaging or prosthesis-forming projection which can be at an angle to the longitudinal axis of the implant, or lie on the longitudinal axis of the implant.

Abstract: A dental implant anchor includes a body portion having a first external wall portion carrying one or more circumferential projections separated by circumferential grooves and, below, a second external wall portion carrying threads. The implant can include a head portion with a smooth external wall; a through-hole and an apical hole passing through the bottom of the implant; and internal structure for engaging a tool for inserting the implant in a passage formed in bone tissue. This internal structure can be in a top portion, or in an internal passage in the body portion of the implant. The method for forming a passage in bone tissue to receive the implant includes forming a passage having a base with a diameter suited to self-tapping of the threaded part of the implant, and, above the base, a larger-diameter section to engage frictionally the circumferential projections.

Abstract: A substantially cylindrically-shaped dental implant includes on its outer surface one or more longitudinally-extending grooves and, near the base of the implant, one or more transversely-extending openings that communicate with the grooves and with a chamber internal to the implant. The chamber also communicates through an upwardly-extending passage with an apical opening at the base of the implant to permit tissue, fluids and debris to escape from a jawbone opening formed to receive the implant.

Abstract: A tiltable, rotatable, adjustable, castable insert adapted for use with dental implants includes two parts: first, a shaft with a receptacle attached to the shaft; second, within the receptacle, a tiltable, rotatable, adjustable prosthesis connector.

Abstract: A handle adapted for engaging, holding and delivering a dental implant to a surgical site, and for holding a dental implant within a package for the implant comprises a body section with a middle portion adapted to fit into a container for the implant; a flange portion connected to the middle portion and adapted to engage an opening in the implant container; a first end portion connected to the middle portion and including an implant-engaging configuration internal or external to the handle; and a second end portion connected to the flange and including a configuration suitable for engaging an implant-insertion tool. The body portion includes an internal passage adapted to receive a shaft that includes a portion for securing an implant to the handle at the implant-engaging configuration.

Abstract: A dental implant anchor includes a body portion having a first external wall portion carrying one or more circumferential projections separated by circumferential grooves and, below, a second external wall portion carrying threads. In some forms, the anchor also includes one or more longitudinally-oriented grooves on its exterior wall. The grooves extend across, and through the circumferential projections. The implant can include a head portion with a smooth external wall; a through-hole and an apical hole passing through the bottom of the implant; and internal structure for engaging a tool for inserting the implant in a passage formed in bone tissue. This internal structure can be in a top portion, or in an internal passage in the body portion of the implant.

Abstract: A screw-type dental implant anchor includes an externally-threaded body portion having internal structure for engaging an insertion tool. The body portion can be joined to a top portion having an unthreaded exterior wall. This internal is inside a top portion or inside the body portion of the anchor. The top portion is open, preferably chamfered at its upper end, and in registration with an internally-threaded shaft inside the body portion of the anchor that extends from a plane just below the head portion downwardly a substantial distance inside the body portion. The distal end of the anchor includes a through hole extending from one side of the body portion to the other, and an opening at the bottom of the body portion extending upwardly inside the body portion a distance sufficient to permit bone and associated tissue to grow into and through these openings and to permit blood tissue to escape.

Abstract: A thermoplastic, one-piece coping insert adapted for use with a dental implant anchoring means includes a shaft that fits into an opening in a dental implant, an abutment head joined to the shaft and adapted to conform to, and fit smoothly on, or in the top surface of the dental implant, a bendable restriction or groove to facilitate preferential bending of the insert at the restriction when the insert is heated to the softening temperature of a thermoplastic, and a relatively unbendable post atop the restriction for receiving and supporting a dental prosthesis such as one or more prosthetic teeth.
