Abstract
A wire-bending plier set for permanently twisting a portion of orthodontic arch wire about the wire axis to enable application of a torque force to a malpositioned tooth. The plier is configured to grip the wire at spaced-apart positions between which the twisting bend is to be made. A lever or key is then engaged with the wire between the gripped areas, and the key is rotated about the wire axis to stress the wire beyond the elastic limit and impart the desired twist.
