The invention relates to an implant element for permanent anchorage in bone
tissue in which at least the surface intended to face the tissue in the
implantation region is made of a biocompatible material such as titanium
and having a clinically well documented surface. The element is provided
with a thin, uniform and adherent calcium-phosphate coating with a well
controlled dissolution rate. The coating follows the topography of the
underlying well documented surface in order to combine properties for
rapid bone growth during the healing phase and properties for a guaranteed
long-term stability during clinical loading conditions.
