TruFlex Thermal NiTi is provided in the martensitic or soft and pliable state and becomes super elastic once it reaches the transformation temperature of 90°F/32°C and becomes activated or austenitic. TruFlex Thermal provides gentle, lower force levels and a smooth, bright finish. The extreme pliability of Truflex Thermal wires offers easy ligation and therefore larger size wires can be introduced at earlier phases in treatment without compromising patient comfort.
