Abstract: An anchoring element and an dental anchoring member for fixation in a first bone tissue and in a second bone tissue, each comprising an apex (1, 12) and 5 a first fixation portion (3, 13) disposed at the apex (1, 12), both adapted for fixation in the first bone tissue, a basis (6, 16), and a second fixation portion (5, 15) disposed at said basis (6, 16) and adapted for fixation in the second bone tissue, and an intermediate portion (4, 14). The second fixation portion (5) of the anchoring element has the form of a truncated cone while the second fixation portion (15) of to the dental anchoring member is threaded and comprises at least one groove forming cutting unit transverse to the threads and disposed at the intermediate portion (14).

Abstract: An elongate cylindrical body member is adapted for permanent anchoring of its lower end into bone tissue and constructed to support an attached device such as a tooth at its upper end. The body member has an external screw thread formed in its outer surface, and at least one cavity defined therein adjacent its bottom end. Each cavity forms at its intersection with the screw thread at least one cutting edge for self-tapping as the body member is screwed into the bone tissue. Such cavity defines a total volume within the outer surface of said body member sufficient to retain all the bone tissue material which is removed as a result of the self-tapping operation.
