Clinical Tip
Both are pre-bendable controlled-memory systems. HyFlex CM runs every file at 500 RPM / 2.5 Ncm and is reusable, regenerating its shape in the autoclave; EdgeFile X7 is single-use in Fire-Wire wire at 300–500 RPM with a 25/.04 crown-down start. Choose HyFlex CM when reuse and shape regeneration matter, X7 when you want a sterile single-use .04/.06 matrix.
