Low‐level laser therapy vs Conventional orthodontic appliance treatment

Orthodontic tooth movement (OTM) during alignment stage · Adolescents and adults with malocclusion undergoing fixed orthodontic appliance treatment

It is very uncertain whether low level laser therapy (LLLT) changes rate of orthodontic tooth movement during alignment stage… compared with conventional orthodontic appliance treatment (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).

Thermoelastic copper NiTi (CuNiTi) arch wire vs Conventional (stabilised) NiTi arch wire

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

It is very uncertain whether thermoelastic copper NiTi (CuNiTi) arch wire changes alignment rate compared with conventional NiTi arch wire (very low certainty).

Thermoelastic copper NiTi (CuNiTi) arch wire vs Conventional (stabilised) NiTi arch wire

Time to alignment · People receiving orthodontic treatment with fixed appliances (upper and/or lower full arch)

Thermoelastic copper NiTi (CuNiTi) arch wire showed no clear difference in time to alignment (alignment rate ratio) compared with conventional NiTi arch wire (low certainty).
