Abstract
An endodontic reamer () and a method for manufacturing endodontic reamers () and files, more specifically an endodontic reamer () having a cylindrical shaft () and a working portion () extending forward from a removed end of the shaft. The working portion () includes, typically, a pair of wedged shaped projecting sections () that extend beyond the diameter of the shaft (). Forward from the wedge shaped sections () is a nose, typically noncutting nose (), that has a diameter of about equal to the diameter of the shaft (). There are typically two wedge-shaped sections projecting outward opposite one another. A novel method is provided for manufacturing an endodontic reamer (), which consists of using a two-piece mold and a wire blank between the mold, followed by forcing the mod together, under compression, against the wire blank, to deform the blank into the shape of mold parts.
