Abstract:
1. A process for manufacturing a dental instrument having a working portion, the process comprising the steps of: providing a wire and dies, said wire being made of a material having a diameter and said dies having walls defining, at least in part, a shape of said working portion of said dental instrument having opposed tapered surfaces, a nose and at least a pair of wedges; placing said wire adjacent to said dies; applying a compressive force to said wire, sufficient to deform said wire into a shape reflecting said walls of said dies transforming said wire into a deformed wire and to create a working portion of said wire; and releasing said deformed wire from said dies; wherein said working portion comprises at least the pair of wedges which extends beyond a radius R of said wire as measured perpendicular to a longitudinal axis of said wire and the nose, located forward of the wedges, each of said wedges having a larger traverse span than the diameter of the wire and a cutting portion proximate the nose.
