• HyFlex™ EDM - up to 700% higher fracture resistance


HyFlex™ EDM

Root Canal Shaping

  • Up to 700% higher fracture resistance
  • Specially hardened surface
  • Less filing required for treatment success


The new HyFlex EDM files constitute the 5th generation root canal files. HyFlex EDM NiTi files have completely new properties due to their innovative manufacturing process using electric discharge machining. 

Workpieces are machined in the EDM manufacturing process by generating a potential between the workpiece and the tool. The sparks generated in this process cause the surface of the material to melt and evaporate. This creates the unique surface of the new Niti files and makes the HyFlex EDM files stronger and more fracture resistant. This entirely unique combination of flexibility and fracture resistance makes it possible to reduce the number of files required for cleaning and shaping during root canal treatments without having to compromise preservation of the root canal anatomy.

Just like HyFlex CM files, HyFlex EDM files have the already familiar controlled memory effect (CM). This results in very similar properties in terms of material flexibility and regeneration.

Unmatched Flexibility and Fracture Resistance in a Pre-Sterile, One File System


HyFlex EDM is the newest innovation in controlled memory rotary endodontics, featuring unmatched flexibility and fracture resistance in a one-file system. Fabricated using EDM (electrical discharge machining) breakthrough technology, HyFlex EDM offers up to 700% greater fracture resistance compared to traditional Niti files (Int Endod J. 2015 May 22. doi: 10.1111/iej.12470).

The combination of strength, flexibility and cutting efficiency of the HyFlex EDM makes it possible to reduce the number of files required to one or two while preserving canal anatomy. Provided as a modular system of sterile instruments, HyFlex EDM includes Shaping, GlidePath, OneFile, Orifice Opener, and Finishing files.

"These files definitely know their way around curves. That‘s for sure. I love them!"
