Continuous-rotation NiTi shaping files. Heat-treated alloys (gold, blue, controlled-memory) offer improved cyclic-fatigue resistance compared with traditional superelastic NiTi.
Dentsply — heat-treated NiTi, multi-file (S1–F5). The reference rotary.
Dentsply — mixed-alloy current generation (Slider, Shaper, F1–FXL).
Coltene — EDM-finished, highly fracture-resistant single-file finisher.
FKG — expands at body temperature to reach isthmuses and oval canals.
