ABSTRACT:
A unitary, molded elastomeric wedge for rotating a tooth about its long axis during orthodontic treatment has a base which functions as a wedge portion, as well as two ligature loops connected to the base. In use, the loops cross over each other and function to ligate the archwire to the bracket while retaining the base in place. The wedge may be installed without removing the archwire from the bracket.
