Amount of crowding · Children or adolescents (aged 16 years old or under) receiving orthodontic treatment to prevent or correct crowded teeth
It is very uncertain whether lower lip bumper changes amount of crowding (change in mandibular incisor crowding) at 6 months compared with no active treatment (control) (very low certainty).

Crossbite correction · Children and adults with a posterior crossbite, without a Class III skeletal relationship, cleft lip or palate (or both), or other…
Fixed tooth-borne expansion (quad-helix) leads to higher crossbite correction compared with observation (no treatment) (high certainty).

Fixed tooth-borne expansion (quad-helix) may leads to higher canine expansion (inter-canine distance) compared with observation (no treatment) (low certainty).

Amount of crowding · Children or adolescents (aged 16 years old or under) receiving orthodontic treatment to prevent or correct crowded teeth
It is very uncertain whether vibrational appliance with fixed appliances changes amount of crowding (change in mandibular crowding) at 10 to 30 weeks compared with fixed appliances only / no vibrational appliance (control) (very low certainty).

Amount of crowding (change in mandibular crowding) at 8 weeks · Children or adolescents (aged 16 years old or under) receiving orthodontic treatment to prevent or correct crowded teeth
It is very uncertain whether nickel-titanium archwire changes amount of crowding (change in mandibular crowding) at 8 weeks compared with stainless steel archwire (very low certainty).
