The distance screw (7) is provided with an upper bore (25) for securing of a cap (4) embedded in the prosthesis construction. The upper part of the distance member is designed to be accommodated within a conical, upwardly narrowing delimiting surface defined by the said cap (4). The upper part (17) of the sleeve-shaped element has a conical peripheral surface (18) with an engagement part (14) designed to cooperate with a tubular counterstay (29) in a fitting tool, and the distance screw (7) also has a conical peripheral surface which forms an extensions of the conical upper part (17) of the sleeve-shaped element, and which has an external engagement part designed to cooperate with a second part, a tightener (27) in the fitting tool. The design of the distance member permits a low distance height and facilitates handling.
