An implant intended to be at least partially implanted into a bone, the implant including an implant part having an endosseous surface. The endosseous surface includes at least one zone having a surface topography exhibiting an arithmetic mean peak curvature parameter (Spc) which is less than or equal to 1 μm, and a density of peaks parameter (Spd) greater than or equal to 0.020 μm.

Bone-anchored implant, and method for manufacturing such an implant

The present invention is directed to a porous pre-densified CeO-stabilized ZrOceramic having a density of 50.0 to 95.0%, relative to the theoretical density of zirconia, and an open porosity of 5 to 50% as well as to a densified CeO-stabilized ZrOceramic having a density of 97.0 to 100.0%, relative to the theoretical density of zirconia, and wherein the grains of the ceramic have an average grain size of 50 to 1000 nm, methods for the preparation of the pre-densified and densified ceramics and their use for the manufacture of dental restorations.
