Abstract

A device for relocating a lower jaw relative to an upper jaw having a first sleeve with a first holder mounted on its one end, and a second sleeve. An internal thread is located in one of the two sleeves and a matching external thread on the other sleeve, by which they are screwed together over varying lengths. A third sleeve having one end, i.e. the end facing the first holder, is mounted on the second sleeve and is adapted to dampen impacts that may act in the longitudinal direction. A rod is arranged in the third sleeve for longitudinal displacement. A second holder is mounted outside the third sleeve on that end of the rod which faces away from the first holder. A stop is provided on the rod or in the neighborhood of the second holder, and abuts directly or indirectly against that end of the third sleeve which faces away from the first holder and toward the second holder. The length of the rod is selected to ensure that in its abutting position it will extend right into the first sleeve.
