US 2006/0137184 A1 · Method for manufacturing endodontic reamers and files

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.

Dependent claims

A process for manufacturing a dental instrument having a working portion, the process comprising the steps of:

providing a wire and a die, said die having walls defining, at least in part, the shape of said working portion of said dental instrument;
placing said wire adjacent to said die;
applying a compressive force to said wire, sufficient to deform said wire into a shape reflecting said walls of said die transforming said wire into a deformed wire and to create a working portion of said wire;
and
releasing said deformed wire from said die.
