The superelastic nickel-titanium arch wire is a kind of ordinary nickel-titanium wire, which has strong elasticity after special treatment.
It relies on unloading external stress to provide long-term and stable orthopedic force for tooth correction,
and achieves the effect of aligning the dentition and leveling the dental arch.
Mainly divided into round wire and square wire
The elasticity is better, and the friction between the bracket and the bracket is small, which is beneficial to the movement of the teeth, so it is often used for correcting the initial stage and aligning the dentition.
The square arch wire interacts with the bracket gap to help control the direction of movement of the teeth, so the square arch wire is often used in the middle and later stages of the treatment.
