Superelastic NiTi arch wire vs Thermoelastic NiTi arch wire

Root resorption · People receiving orthodontic treatment with fixed appliances (upper and/or lower full arch)

It is very uncertain whether superelastic NiTi arch wire changes root resorption (reduction in root length) compared with thermoelastic NiTi arch wire (very low certainty).

Single-strand superelastic NiTi arch wire vs Coaxial superelastic NiTi arch wire

Alignment rate · People receiving orthodontic treatment with fixed appliances (upper and/or lower full arch)

Single-strand superelastic NiTi arch wire probably leads to lower alignment rate compared with coaxial superelastic NiTi arch wire (moderate certainty).
