Vibrational appliance with fixed appliances vs Fixed appliances: Amount of crowding

Population
Children or adolescents (aged 16 years old or under) receiving orthodontic treatment to prevent or correct crowded teeth
Intervention
Vibrational appliance with fixed appliances
Comparison
Fixed appliances
Outcome
Amount of crowding

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).

How reviews are matched to this question

Reviews word the same question differently. Four decision models (TypeSafe's Jev, Liquid AI's d1-ultra, SubQ Snap and Baseten's Elephant) judged each wording of the population, intervention, comparator and outcome against the others; two wordings count as the same when at least three of them agree and none clearly disagrees, and findings count as this question only when all four elements match. Timing, setting and subgroup never split a question: they are shown on each finding.
