Comparison of AdvanSync and intermaxillary elastics in the correction of Class II malocclusions: A retrospective clinical study

AdvanSync and intermaxillary elastics were effective in normalizing Class II malocclusions during comprehensive fixed orthodontics. AdvanSync produced its effects through maxillary skeletal growth restriction and mandibular dentoalveolar changes. Class II elastics worked primarily through dentoalveolar changes in both the maxilla and the mandible.
