Nickel Titanium Arch Wire is an alive wire that constantly attempts to move back to its original shape. This wire shortens the treatment time required for rotations and leveling. It produces less patient discomfort and requires fewer wire changes than stainless steel wire. Our product is highly polished and always midline marked and will take a step up, a step down, or a cinch. Our Nickel Titanium will not make closing loops. Made of 50% Nickel and 50% Titanium.
