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 ). A dental anchoring unit for fixation in the os zygomaticum, the dental anchoring unit being elongated and comprising an apex ( 24 ) and a fixation portion ( 25 ) disposed at the apex ( 24 ), both adapted for fixation in the os zygomaticum, a basis ( 26 ), and an end portion ( 27 ) disposed between the fixation portion ( 25 ) and said basis ( 26 ). The fixation portion ( 25 ) has the form of a truncated cone having the smaller basis adjacent to the apex ( 24 ) and the larger basis adjacent to the end portion ( 27 ). |
