Comparison of the load-deflection characteristics of 0.012″ heat-activated, superelastic and bent superelastic nickel titanium wires

ConclusionsAfter any deflection, all bent NiTi wires produce lighter forces at 0.5 mm after deactivation than superelastic NiTi and heat-activated NiTi wires. This study indicates bending a NiTi wire close to a displaced tooth with up to 1 mm deflection can produce an active light deactivation force to level severely displaced teeth.
