PCT No. PCT/SE95/00217 Sec. 371 Date Jan. 19, 1996 Sec. 102(e) Date Jan. 19, 1996 PCT Filed Mar. 2, 1995 PCT Pub. No. WO95/23561 PCT Pub. Date Sep. 8, 1995A spacing member for a securing element (fixture) permanently anchored in the jawbone. The spacing member comprises a substantially sleeve-shaped spacing element to be fitted on the securing element and a separate spacing screw. The spacing screw has an elongate, unthreaded middle portion and a threaded portion at its tip for engaging with an internally threaded bore in an upper part of the securing element. The sleeve-shaped spacing element includes a passage extending longitudinally therethrough for receiving the spacing screw. The passage has an internally threaded portion for engaging with the spacing screw, so that the spacing screw, after it has been threaded through the threaded portion, is joined together with the spacing element, and a recess in an upper part of the passage. The recess has a non-circular geometry for facilitating application of a counter-holding instrument in order to prevent the tightening force from being transmitted down into the securing element when the sleeve-shaped spacing element is fitted on the securing element.
