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.Des modes de réalisation de la présente invention concernent un implant pour osséo-intégration et des outils, des composants et des techniques de fabrication associés pour des applications de fixation dos chirurgicale et de restauration dentaire. Un mode de réalisation concerne un implant fileté ou ajustable par pression en une pièce tout en céramique qui a des caractéristiques de surface finement détaillées formée par moulage par injection de céramique et/ou frittage par étincelles de plasma dune poudre compactée ou dun corps cru comprenant de la zircone finement pulvérisée. Un autre mode de réalisation concerne un implant fileté en deux pièces
