Abstract
A device for the registration of a mandibular position that is protruded relative to the normal position, with an impression plate that is flat on both sides and whose shape corresponds to the bite of the upper and the lower jaw, whose inner and outer contour is U-shaped, that comprises, in the area of the limbs of the U, finger-like registration surfaces that extend from the inner contour to the outer contour and are arranged at a distance from each other, and that is capable of limited elastic deformation in this area. Centered in relation to the limbs of the U, bite cones for accepting the upper incisors are arranged on the upper surface of the impression plate. A shaft that is of one piece with the impression plate, is centered on the impression plate, extends in an extension of the bite cones, serves for the manipulation as well as a holder of an element that can be moved in the longitudinal direction relative to the shaft, can be moved in a longitudinal slot, and has bite cones on its underside for accepting the lower incisors. Due to its thinness and deformability, the device permits the production of removable registrates with only a small increase of the occlusal height. D…
