Abstract: A dental sub-assembly for individual prosthetic restoration of a tooth is shaped so as to be received on a dental implant. The dental sub-assembly is able to be assembled with a first element in the form of a core on which stratification is performed, or in the form of a ceramic core. The first element has a first through-passage. The dental sub-assembly includes a ring intended to be fitted into the first through-passage of the first element and to be retained firmly in order to form there a seat for a first fastening screw intended to be screwed into the dental implant.

Abstract: Embodiments of the present invention provide an osseointegrative implant and related tools, components and fabrication techniques for surgical bone fixation and dental restoration purposes. In one embodiment an all-ceramic single-stage threaded or press-fit implant is provided having finely detailed surface features formed by ceramic injection molding and/or spark plasma sintering of a powder compact or green body comprising finely powdered zirconia. In another embodiment a two-stage threaded implant is provided having an exterior shell or body formed substantially entirely of ceramic and/or CNT-reinforced ceramic composite material. The implant may include one or more frictionally anisotropic bone-engaging surfaces. In another embodiment a densely sintered ceramic implant is provided wherein, prior to sintering, the porous debound green body is exposed to ions and/or particles of silver, gold, titanium, zirconia, YSZ, α-tricalcium phosphate, hydroxyapatite, carbon, carbon nanotubes, and/or other particles which remain lodged in the implant surface after sintering. Optionally, at least the supragingival portions of an all-ceramic implant are configured to have high translucence in the visible light range. Optionally, at least the bone-engaging portions of an all-ceramic implant are coated with a fused layer of titanium oxide.

Abstract: Disclosed is a dental prosthetic device having an implant, a cap and an abutment interposed between the implant and the cap. The abutment includes an abutment head which is at least partially delimited by an abutment external face and which is configured to retain the cap. The abutment has an abutment body with an attachment to the implant. Retention is accomplished by a nesting arraignment for fitting the abutment head inside a cavity which is formed inside the cap and which is at least partially delimited by a cap internal face. The cap is screwed onto the abutment head. The cap internal face is provided with a tab which is in contact against the abutment external face. A space is left between a point of contact of the cap internal face and a cone lip of the cap internal face between the abutment external face and the cap internal face.

Abstract: A multi-unit abutment aligning a dental implant and a screw-attached prosthesis with copings is disclosed. The multi-unit abutment has a threaded base post for attachment to the implant and a ball portion. A swivel post into the implant with the multi-unit assembly in a linear configuration. The swivel shell is then positioned and fixed at a desired tilt and azimuthal angle. The swivel shell has a mating surface for a coping. The lock screw remains accessible through an aperture in the coping when the prosthesis is positioned on the implant abutments. Different embodiments are disclosed for capturing the swivel shell on the ball. Methods for improving passive alignment of the prosthesis to the implants are described.

Abstract: A zygomatic implant for supporting a dental bridge is provided. The zygomatic implant has a stem with a longitudinal axis having a threaded apical portion, an intermediate portion, and a neck portion having a seat for attachment of an abutment. The zygomatic implant has a head with a polygonal cross section that protrudes atop the neck portion, and two internal threads, each having an axis orthogonal to the longitudinal axis of the stem and a mouth located on a lateral wall of the stem. The two internal threads are arranged longitudinally offset along the longitudinal axis of the stem.
