Claim:
1. A pliers for crimping coils of an orthodontic torquing spring to an arch wire comprising: a pair of plier halves, each of the plier halves including a handle, a jaw, and a pivot section, each of the jaws including a substantially rectangular shaped crimping face defined by a distal edge having a length in a range of 200 percent to 400 percent of a diameter of the orthodontic torquing spring, a first lateral edge, and a second lateral edge that extend substantially perpendicularly from the distal edge, where each of the distal edge, the first lateral edge and the second lateral edge have a radius of curvature in a range of 0.1 millimeters to 0.5 millimeters; a textured surface on at least one of the substantially rectangular shaped crimping faces to frictionally engage the coil of the orthodontic torquing spring; and a pivot joint connecting the pivot sections of the pair of plier halves such that the handles can be manipulated to cause the substantially rectangular shaped crimping faces of the jaws to move together to crimp a coil of the orthodontic torquing spring to the arch wire.
