Single-File Reciprocating Shaping

Clinical Tip

Same manufacturer, same C.Wire heat treatment, two motions. One Curve shapes with a single 25/.06 in continuous rotation at 300 RPM / 2.5 Ncm on any rotary motor and can be pre-bent; One RECI reciprocates at 170° CCW / 60° CW on a motor with programmable angles across five sizes (20/.04 to 45/.04), and its IFU excludes retreatment use. Choose One Curve for rotary simplicity, One RECI when you prefer reciprocation and have the motor for it.
