This retrospective non-randomized controlled clinical trial aimed to compare the skeletal and dentoalveolar effects of two orthopedic treatment protocols for skeletal Class III malocclusion in growing patients: a conventional tooth-borne rapid maxillary expansion combined with facemask therapy, and a hybrid skeletal anchorage expander combined with chin-plate traction. Lateral cephalometric changes before and after maxillary protraction were analyzed to assess sagittal skeletal correction and dentoalveolar effects.
