FireWire Heat Treatment

FireWire is EdgeEndo's proprietary annealed heat treatment applied to NiTi wire, resulting in a predominantly martensitic alloy at body temperature with minimal shape memory. The process yields files with no imposed canal transportation forces, as the file conforms passively to canal curvature. EdgeEndo reports FireWire-treated files achieve up to 5× greater cyclic fatigue resistance compared to WaveOne Gold, with WaveOne-compatible motor settings for easy integration into existing reciprocating motor programs. FireWire systems are available in both continuous rotation (EdgeFile X7) and reciprocating (EdgeOne Fire) configurations.
