Two part implant for attachment of artificial teeth comprising a base body having a bone contact surface and a soft tissue contact surface. The soft tissue contact surface is at least partially hydroxylated or silanated which results in an improved soft tissue integration.

A dental implant has a coronal body formed of solid metal that connects at an interface to a bone fixation body. The bone fixation body is made separately from the coronal body and has a porous structure with a cylindrical shape. The bone fixation body connects to the coronal body after the bone fixation body is separately made from the coronal body.

The present invention provides an implant body formed from metal or ceramics as a raw material, the implant body including a modified surface, provided with a plurality of projections and a plurality of crevasse-like nanoscale grooves, by which focal adhesion formation, penetration of collagen fibers, arrangement of the collagen fibers in a single direction to thereby adhere to connective tissue, and soft tissue sealablity are possible. According to such a surface modification, focal adhesion formation and the arrangement of the cell cytoskeleton can be enhanced, and penetration of collagen fibers into the surface internal portion is possible.

A method of manufacturing a dental implant wherein the resulting dental implant closely corresponds to or matches the size and shape of the extracted tooth. Generally stated, the method comprises the steps of (i) three dimensionally mapping the size and shape of the crown and root of a tooth to be extracted and (ii) using said mapping to manufacture a dental implant to correspond to the size and the shape of said crown and root of the tooth to be extracted. Further, the resulting dental implant may comprise a number of anti-migratory structural features that function to better secure the dental implant to the patient.

An implant is provided with an upper portion in which an internal socket extends. The implant can be tightened by a turning instrument which has first lateral surfaces that can cooperate with corresponding second lateral surfaces in the internal socket. One or more of the first and/or second lateral surfaces is/are arranged completely or partially with friction-enhancing means. The implant and the tool are arranged with interacting parts which extend beyond the first and second lateral surfaces and completely or substantially take up bending moments which act in or on said portion or are directed toward said portion and occur in the event of skewing, or a tendency toward skewing, between the implant and the tool. The arrangement counteracts mechanical stresses in said portion, the latter being able to retain its original shape even in the case of implants with small dimensions.

A dental implant assembly comprising an elongated inner body substantially resembling a tooth root (1-1) and an outer member for securing to a bone of a patient (1-2) having a heterogeneous porous structure adapted to provide bone growth, the inner body and the outer fixation member being formed in one piece, the fastening element being movable between a stored passive position and an extended active position (1-2).

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, ?-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.

A titanium 6 A1/4V alloy is provided with a surface topography that is similar to the Osseotite surface produced on commercially pure titanium. Native oxide is removed from the Ti 6A1/4V alloy, followed by contacting the metal at ambient temperature with an aqueous hydrochloric acid solution containing a relatively small amount of hydrofluoric acid.

An implant having a nanopatterned dimple surface and a method of preparing the same are provided, the method including forming titanium oxide nanotubes by anodizing an implant body composed of titanium or a titanium alloy and forming dimples on the surface of the implant body by removing the titanium oxide nanotubes. The surface of the implant body is anodized and the anodized surface is then removed, thus forming surface dimples, whereby the anodized titanium oxide film can be prevented from being released into the living body due to exfoliation thereof and impurities remaining on the surface can be effectively removed. When a bio-implantable titanium or titanium alloy is used as an implant body material, the surface area thereof can be maximized upon bio-implantation due to dimples formed through surface anodization, thus exhibiting superior biocompatibility, chemical stability and mechanical stability, and anodization is performed together with sandblasting or SLA (Sandblasting, Large-grit, Acid etching), thereby forming roughness having various sizes, including nanopatterns.

A dental implant and a method for manufacturing same which assure early stability and fixation power of an implant by suppressing early osteolysis after an implant procedure, and allowing better bone coherence of the implant surface during an osteogenic period by controlling the speed of bone remodeling.
