    • 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.
    • 用于校正人牙不对准的装置包括杆状构件,该杆状构件具有用于将连接线固定到支架的夹持保持器和施加到牙齿的托架。 夹持器连接到布置在手管和端管内部的杆状管状扭力杆。 在扭杆的外圆周上形成螺纹,其经由球保持器与形成在手管上的螺纹配合。 旋转运动通过手管或端管的轴向运动而被施加到扭杆,从而赋予夹持器。 作为这种旋转运动的结果,插入到握持器中的连线的端部被扭转以固定在支架中引导的支架,因此支架固定到支架以将支架的力传递到齿。 因此,与其他固定方法相比,固定加快和简化。
