<p>The invention relates to a rotationally symmetrical anchoring element for anchoring in bone tissue, for example permanent anchoring of artificial teeth and dental bridges in the jaw bone. The anchoring element is made of a biocompatible material and has a circumferential surface which includes a lower portion (6) intended to be incorporated with bone tissue, and an upper portion (9) which, following implantation, is located outside the bone tissue for the purpose of attachment of a spacer piece (12) or a prosthetic structure. The said upper portion (9) includes a smooth (unthreaded) conical portion (9) whose diameter increases in the direction away from the upper end surface (gable surface) (7) of the element. The conical portion (9) forms a bearing surface for the spacer piece (12) or the prosthetic structure.</p> |
