Intraoral vertical ramus osteotomy (IVRO) vs Sagittal split ramus osteotomy (SSRO): Stability of correction: sagittal changes of B-point (1 week to 1 year)
- Population
- Adults (16 years of age or older) with an Angle Class III malocclusion (prominent lower front teeth); people with syndromes, clefts or traumatically-induced deformities excluded
- Intervention
- Intraoral vertical ramus osteotomy (IVRO)
- Comparison
- Sagittal split ramus osteotomy (SSRO)
- Outcome
- Stability of correction: sagittal changes of B-point (1 week to 1 year)
Intraoral vertical ramus osteotomy (IVRO) showed no clear difference in stability of correction: sagittal changes of B-point (1 week to 1… compared with sagittal split ramus osteotomy (SSRO); GRADE not reported.

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.
