Coltene's HyFlex EDM is a state-of-the-art endodontic rotary file designed for efficient and precise root canal preparation. It features the latest technology in manufacturing, called "Electrical Discharge Machining" (EDM), which utilizes spark erosion to harden the surface of the nickel-titanium (NiTi) file.

Features and Benefits:

• Superior Fracture Resistance: The EDM process used in the production of HyFlex EDM results in a hardened surface that makes it highly resistant to fracture. This feature is especially beneficial when working with curved or calcified canals, where traditional files are more prone to break or deform.
• Improved Cutting Efficiency: The hardening effect of the EDM process also improves the cutting efficiency of HyFlex EDM. This means that the file can easily penetrate and negotiate even the most challenging canal anatomies, resulting in faster and more precise root canal preparation.
• Flexibility: Despite its superior strength, HyFlex EDM maintains its flexibility, allowing for controlled linear advancement and better control during use. This flexibility is essential in ensuring minimal stress on the root canal walls, which can lead to complications such as perforations or fractures.
