Device for regulation of tooth position, comprising three elements sliding along U-shaped base

摘要

Three individually movable sliding segments (5-7) are arranged along a U-shaped bow (1) and can be controlled with threaded bolts (16-18) positioned between the arms (3,4) of the bow. Each bolt is guided through an opening in a bolt holding element (13-15) connected with each of the sliding elements. When the bolt is rotated the element is moved along the U-shaped base, acting on the particular tooth to be corrected at a time and facilitating the regulation of the position of a group of more than two teeth.
