Abstract

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.
