Clinical Tip

EdgeOne Fire is a single-file reciprocating system at 150°/30° with WaveOne-compatible motor settings and its own GlidePath file; the manufacturer cites bench data for its FireWire treatment against Gold-treated NiTi. ZenFlex is a ten-file controlled-memory rotary matrix at 500 RPM with torque set per taper and size, pre-bendable, and can also run in Adaptive Motion on a Kerr motor. Choose EdgeOne Fire if your motor already carries a WaveOne preset, ZenFlex for graduated rotary shaping in controlled-memory wire.
