000000794 520__ $$aThis retrospective chart review compared treatment outcomes of cervical versus high-pull headgear in Class II patients with high mandibular plane angles (MP-SN > 36°). Sixty-two patients were treated with straight-wire appliances and adjunctive mechanics as needed. Pretreatment and posttreatment cephalograms were digitized and analyzed, and intergroup differences were assessed with independent t-tests. Sagittal changes were similar between groups. Vertically, the cervical headgear group showed greater increases in Y-axis angle, occlusal plane angle, and lower facial height. Despite some statistically significant differences, changes were small and of limited clinical significance, suggesting both headgear types are acceptable treatment options.
