Our Goal of modified segmental osteotomy on maxilla accompanied by mandibular anterior subapical osteotomy was to get the best results from patients of bi-alveolar or bi-maxillary protrusion. In this study, cephalometric and photo (en face, profile) analysis have been compared to define the soft tissue change after surgery. Lip protrusion was efficiently reduced and nasolabial angle was much obtused. Although nose was a little widened, it was quite acceptable. Blood circulation on osteotomized segment was well maintained. This relatively simple methods could be successfully applied to many patients.

This paper describes the case of a 50-year-old female with a Class II malocclusion who presented with severe bimaxillary protrusion and generalized alveolar bone loss due to adult periodontitis. The treatment plan consisted of extracting both upper and lower first premolars and periodontal treatment. Anterior segmental osteotomy(ASO) of the mandible and upper anterior segment retraction using compression osteogenesis after peri-segmental corticotomy(Speedy orthodontics) was performed. Correct overbite and overjet, facial balance, and improvement of lip protrusion were obtained. However, a slight root resorption tendency was observed on the lower anterior dentition. The active treatment period was 9 months and the results were stable for 27 months after debonding. This new type of treatment mechanics can be an effective alternative to orthognathic surgery.
