Intraoral distalising appliance vs Headgear (extraoral appliance): Movement of upper incisor teeth (mm)
- Population
- Children and adolescents (aged 16 years or less at the start of treatment) undergoing orthodontic treatment to distalise upper first molars; patients with cleft lip and palate or other craniofacial problems excluded
- Intervention
- Intraoral distalising appliance
- Comparison
- Headgear (extraoral appliance)
- Outcome
- Movement of upper incisor teeth (mm)
Intraoral distalising appliance may leads to higher movement of upper incisor teeth (mm) compared with headgear (extraoral appliance) (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.
