Class III surgical-orthodontic treatment: a cephalometric study.

摘要: Introduction: In this retrospective study, we investigated treatment outcomes in Class III surgical-orthodontic patients. Methods: Records of 151 consecutively completed patients (overjet, 0 mm or less) were obtained from 87 consultant orthodontists the United Kingdom. Pretreatment and posttreatment cephalometric radiographs analyzed. Results: Bimaxillary surgical (75%) had more negative initial ANB-angle values smaller SNA-angle than those treated with single-jaw mandibular surgery. Mandibular surgery (15%) greater pretreatment prominence (SNB angle) maxillary Maxilla-only (10%) lower overjet bimaxillary An within ideal range 1 to 4 was achieved 83% Logistic regression identified no predictors outcome. SNB angle corrected 75° 81° 44% This less likely only larger SNB-angle values. ANB (1° 5°) 40% surgery, angles, presurgical orthodontic extractions arch. Ideal unadjusted Holdaway angles (7° 14°) 59% when used. Incisor decompensation incomplete 46% associated arch extractions. Conclusions: Surgical-orthodontic a high success rate normalizing soft-tissue profile ranges most frequently used procedure an increased likelihood correction anteroposterior skeletal discrepancy.
