Abstract
A method for supporting a prosthesis or part thereof on bone tissue utilizes an anchoring element (1) that is substantially rotationally symmetrical and is provided with external threads (20) and a central bore (2). At least one slit (3, 4, 5, 6) is arranged in spiral form around the longitudinal axis (13) of the element (1), extending through and over at least the major part (11, 12) of the outer wall of the element to communicate with the central bore. The major part is provided with external threads (20), and the spirality of the slits (3, 4, 5, 6) is the same as that of the outer threads (20). After drilling a hole to completion in bone tissue, an inner end portion of element (1) is forced into the hole while rotating element (1) and utilizing the external threads to cut complementary internal threads in the bone tissue. The prostheses or parts thereof are then secured to the outer end portion of element (1).
