Micro-Mega (COLTENE) Systems
One Shape is the original single-file continuous rotation system with variable asymmetric cross-section. 2Shape provides a two-file workflow with T.Wire heat treatment. One Curve offers single-file rotary shaping with C.Wire controlled memory alloy.

System Comparisons
One Curve vs One Shape
One Curve for controlled-memory, pre-bendable single-file rotary. One Shape for cost-effective single-file rotary in continuous rotation.
One Curve vs One RECI
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.
One Curve vs 2Shape
Same manufacturer, one file versus two. One Curve shapes most canals with a single pre-bendable C.Wire 25/.06 at 300 RPM / 2.5 Ncm, single-use; 2Shape uses TS1 (25/.04) then TS2 (25/.06) in T.Wire at 250–400 RPM, reusable for up to 5 canals per its IFU, and its IFU excludes retreatment use. Choose One Curve for single-file speed, 2Shape for a two-step progression and reuse.
