Comprehensive review reveals stage-dependent efficacy of growth modification, camouflage, and surgery in Class II malocclusion, highlighting tailored approaches based on skeletal maturity.
Key Points
To synthesize classic and current clinical evidence on treatment options for Class II malocclusion across growing and nongrowing patients.
Reviewed evidence across growth modification therapies, orthodontic camouflage techniques, and orthognathic surgical interventions.
Analyzed data from randomized clinical trials and contemporary systematic reviews, including a 2026 meta-review encompassing 65 surgical studies (N=6,482).
Randomized trials demonstrate that early growth modification produces short-term skeletal benefits but fails to reduce the duration or necessity of subsequent comprehensive orthodontic treatment.
A 2026 systematic review identified the Twin Block as the most efficient removable appliance and the Forsus device as the most efficient fixed functional appliance.
In severe adult discrepancies, orthognathic surgery achieves a mean ANB improvement of 5.4°, maintaining skeletal stability in 87.3% of patients at one year with an 87.6% patient satisfaction rate.
