NICKEL-TITANIUM ENDODONTIC ROTARY FILE WITH HYBRID CROSS-SECTION

摘要

Provided in the present invention is a file cross-section structure for endodontic treatment increasing maintenance of an endodontic center of the cross-section structure of radial land and a cutting force of a blade structure at the same time. The nickel-titanium rotary file structure has a composite cross-section structure. The file made of a nickel-titanium alloy includes at least one cutting blade and at least one radial land part sharing the same center of rotation, where the file has a triangular cross-section, and the cutting blade and radial land part independently have an angle between 95° and 110°.
