Clinical Tip

Both are constant-taper .04/.06 systems at 500 RPM. Vortex Blue spans 15–50 in blue heat-treated wire with file-specific torque and a crown-down technique; ZenFlex spans 20–40 in controlled-memory wire with a 1 mm flute diameter, is pre-bendable and can run in Adaptive Motion on a Kerr motor. Choose Vortex Blue for the wider size matrix, ZenFlex for conservative shaping and pre-bent navigation.
