The heat-activated nickel-titanium archwire is adjusted by the temperature of the phase transition point to exert the super-memory performance of the archwire. The clinical manifestation is that under the oral temperature environment, the heat-activated archwire will slowly recover the shape before the stress gradually increases, and Finally, continuous micro-force correction is achieved.
