ABSTRACT:
An orthodontic tool for placing and measuring bends or twists in orthodontic arch wires, or the like, in order to place potential torquing forces in the wire, comprises first and second engaging means for engaging an elongated wire on respective opposite surfaces of the wire, one of the engaging means carrying an indicator member with a scale thereon and the other of the engaging means carrying a pointer. When the two engaging means are placed together and twisted around the arch wire, the pointer will indicate the exact degree of twist being placed in the wire on the indicating scale. The engaging means may comprise pliers, keyed members, or the like. Preferably, the scale is interposed between the engaging means to provide a bending space between the engaging means to prevent weakening of the wire when it is twisted. Also disclosed is a tool for bending orthodontic arch wires to provide second order bends.
