Benefits of technology

[0016] In a further aspect, the instrument or blank may have a coating for improving durability, and / or lubricity and / or improving cutting efficiency and / or strength.
[0063] One end of the shank portion adapted for attachment to a handle portion may be treated. The treatment may improve the attachment strength and minimize separation of the shank portion from the handle portion.
[0064] The substantially 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.

Problems solved by technology

Many endodontic instruments used for this operation have torsional limitations.

Abstract

A method of manufacturing endodontic instruments is disclosed. Each of the instruments includes a substantially non-cutting pilot portion, a relatively short working portion, and a flexible shank portion which is of a substantially smaller average circumferential span than the working portion. The working portion of the instrument has a maximum circumferential span larger than that of the blank from which it is made. The instrument may have a handle at its distal end for manual manipulation, or may be adapted for attachment to a mechanical handpiece. The non-cutting pilot, the short length of the working portion, and the flexibility of the shank combine to allow the instrument to be used in curved root canals without causing undue change in the natural root canal contours.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims the benefit of U.S. Provisional Patent Application 60 / 732,367 entitled “Endodontic Instrument” filed Nov. 1, 2005; U.S. Provisional Patent No. 60 / 732,047 entitled. “Endodontic Instrument” filed Nov. 1, 2005; U.S. Provisional Patent Application No. 60 / 732,631 entitled “Endodontic Instrument” filed Nov. 1, 2005; and U.S. Provisional Patent Application No. 60 / 732,039 entitled “Treated Endodontic Instrument” filed Nov. 1, 2005 the entire contents of which are incorporated by reference.FIELD OF THE-INVENTION [0002] This invention relates to endodontic instruments and a method for manufacturing endodontic instruments in general.
