ABSTRACT:
An orthodontic rotation spring, geometrically shaped as a "U" or an "S", that terminates at one end in a tube for the passage and retention of a tie wire, and at the other end with a curved surface. The entire spring is dimensioned for compression between an arch wire attached to an orthodontic bracket and a tooth band. A force vector results which acts to rotate the tooth about its axis.
