The aim of the study: evaluation of surgically- assisted orthodontics in correction of increased anterior overbite and treatment of gummy smile. Methods: 5 patients with anterior vertical maxillary excess were selected from the outpatient clinic of Oral and Maxillofacial Surgery Department and Orthodontics Department, Faculty of Dentistry, Cairo University. All patients were females, with an age range of 16- 30 years. The increase anterior overbite was corrected by compression osteogenesis, after surgical exposure labial corticotomy cuts performed (1 supra-apical, and bilateral vertical cuts between maxillary canines and first premolars). Compression osteogenesis protocol followed the sequence: latency period then active traction and functional loading on transmucosal mini-screws followed by a consolidation phase. The results showed decreased overbite with less gingival display within a period of time ranging between 4-6 weeks. Conclusion: Increased anterior overbite and gummy smile of skeletal etiology can be fixed under local anesthesia using surgically- assisted orthodontics through anterior maxillary corticotomy and compression osteogenesis.
