Abstract
An apparatus for correcting misalignments in human teeth comprises a rod-like member which has a grip holder for fixing a ligature wire to a brace and to brackets applied to teeth. The grip holder is connected to a rod-like tubular torsion bar arranged in the interior of a hand tube and an end tube. On the outer circumference of the torsion bar are formed threads, which cooperate via a ball cage with the threads formed on the hand tube. A rotary movement is imparted to the torsion bar and thereby the grip holder by an axial movement of the hand tube or the end tube. As a result of this rotary movement, the ends of a ligature wire inserted in the grip holder are twisted for fixing a brace guided in the bracket, and consequently the brace is fixed to the bracket for transferring the force of the brace to the teeth. Therefore fixing is sped up and simplified as compared with other fixing methods.
