The HyFlex EDM OGSF Sequence from Coltene is a nickel-titanium rotary endodontic file system manufactured with Electric Discharge Machining (EDM) and Controlled Memory (CM) heat treatment for exceptional flexibility and high resistance to cyclic fatigue and fracture. The OGSF sequence includes one orifice opener, one glidepath file, one shaping file, and one finishing file, providing a structured progression from glide path to finishing for efficient, predictable canal preparation. The 21 mm length offers improved control and maneuverability in shorter canals and cases with limited access, while the variable cross-section design supports centered preparation and reduces the risk of ledging or perforation. The files are pre-sterile and can be regenerated through heat sterilization for safe reuse.
