An implant element for permanent anchorage in bone tissue in which at least the surface is intended to face the tissue in the implantation region. The element is made of titanium with a titanium oxide surface which has been modified by anodization to acquire an oxide thickness of approximately 10-200 nm. Also acquired are an increased surface oxide crystallinity and a roughness on the submicrometer scale in order to provide a high degree of bone-to-implant contact.
