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 non-cutting nose, that has a diameter of about equal to diameter of the shaft. There are typically two (2) wedge shaped sections projecting outward opposite one another. Applicant also provides a novel method for manufacturing an endodontic reamer, which consists of using a two piece mold and placing a wire blank between the mold, followed by forcing the mold together, under compression, against the wire blank, to deform the blank into the shape of the mold parts.
