Abstract
The invention relates to a method for treating the surface of surgical implants made of titanium or a titanium alloy, for instance dental implants, before implantation in bone tissue. The method results in a roughened exterior implant surface and at the same time a cleaning action is obtained, should there be any contaminants. The surface is blasted with particles of an oxide of titanium, preferably titanium dioxide. In this way an implant having an improved retention in bone tissue is obtained. The blasted implant is used in a method for treating toothlessness.
