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.

Endodontic reamer and files

Endodontic reamer and a method for manufacturing endodontic reamers and files

An endodontic instrument having a shaft with a near end and a removed end. The shaft is comprised of a first material. A head, the head being comprised of a second material is attached to the removed and of the shaft. The shaft is rotated so as to move with the shaft. The head is permanently attached to the shaft. The head is typically shaped to allow for the cutting of dentin or other tooth or pulp material. Applicant also provides a method for manufacturing such an endodontic instrument by including the steps of forming a tooth cutting member such as a head, forming an elongated shaft and permanently attaching the tooth cutting member or head to the shaft.

Endodontic instruments with means for breakage containment

An endodontic instrument in accordance with the present invention includes a substantially non-cutting pilot segment, a relatively short cutting segment, and a flexible shaft segment, which can have a handle at its distal end for manual manipulation, or an adapter for attachment to a mechanical handpiece. The non-cutting pilot, the short length of the cutting segment, and the flexibility of the shaft combine to allow the instrument to be used in curved root canals without causing undue change in the natural root canal contours.
