Powered by BlackPearl Technology & Controlled Memory (CM) Rootshaper SYMMETRY combines Koden's black-oxide BlackPearl Technology (BPT) with Controlled Memory (CM) NiTi wire, delivering a file that bends and folds through even abrupt or S-shaped curvatures without spring back — and visibly restores its shape and strength in the autoclave. BPT's surface treatment enhances fatigue resistance and cutting efficiency, while the CM wire is pre-bendable by hand for precise canal preparation and excellent centering ability. Built for specialist anatomy where predictability through severe curvature matters most.
