Embodiment Construction

[0033] Embodiments of the invention described herein include methods of forming endodontic files by processing an elongated rod formed from a substantially predetermined length of superelastic material by applying appropriate heat and pressure substantially simultaneously. In one embodiment, rod 18 is conical, substantially cylindrical and grooveless prior to processing. Alternatively, the rods may be non-tapered and / or the rods may have various shapes, such as having triangular, rectangular, hexagonal, star-shaped, frusto-cylindrical, asymmetrical polygonal, rhomboid cross-sections, or other various shapes profile. In other embodiments, the rod may be slotted, for example having the helical shape of a conventional endodontic instrument.

[0034] Rod 18 is also preferably formed from a nickel titanium alloy, such as SE508 nickel titanium wire manufactured by Nitinol Devices and Components Inc. of Fremont, California. This is a typical binary nickel-titanium alloy used in end...

Abstract

An endodontic instrument and method for making same is provided. A rod of superelastic material is set into a shaped configuration to form an instrument, such that the instrument may be inserted into a root canal in a configuration different than the shaped configuration and revert towards its shaped configuration during the endodontic procedure.

Description

[0001] Cross References to Related Applications [0002] This application, filed under the Patent Cooperation Treaty (PCT), claims serial number 61 / 095,455 entitled "Endodontic Instrument and Method of Manufacturing," issued September 9, 2008 to John T. McSpadden and Mark S. Ferber Priority to filed U.S. Provisional Patent Application, the contents of which are hereby incorporated by reference in their entirety. technical field [0003] The present invention relates generally to the field of dentistry, and more particularly to endodontic instruments for safe and efficient enlargement of root canals. Background technique [0004] In the field of endodontics, one of the most important and delicate procedures is the cleaning and sweeping of the tooth's elongated, curved, tapered canal to provide a cavity of the correct size while substantially maintaining the canal's original central axis and Size ratio. This step is important in order to be able to fill the canal with as lit...
