The new HyFlex EDM files represent the 5th generation of endodontic files. The NiTi EDM files possess entirely new properties due to their innovative manufacturing process using electrical discharge machining (EDM). This completely unique combination of flexibility and fracture resistance allows for a reduced number of files needed for cleaning and shaping during endodontic procedures without compromising the preservation of the root canal anatomy. Up to 700% greater fracture resistance, with a specially hardened surface, enables instrumentation with a reduced number of files.
