The present invention relates to a screw-shaped titanium anchoring member for permanent anchorage in bone tissue, specifically permanent anchorage of artificial teeth or tooth bridges in the jaw-bone. The tip of the anchoring member comprises at least one cavity (4). The edges of the cavities on the outer cylindrical surface form cutting edges (5) to provide self-tapping when the anchoring member is screwed into the bone tissue. The total volume of the cavities is adapted to contain the scraped-off bone tissue material, i.e. all the scraped-off bone tissue material can be housed in the screw in the volume formed by the cavities. Behind the cutting edges (5) the anchoring member has a clearance surface (9), i.e. behind each cutting edge the surface of the anchoring member is slightly bevelled towards the center of the anchoring member. By means of such clearance surface any squeezing effect which might occur in the cutting portion of the fixture when it is screwed into hard bone tissue can be avoided.
