title: Anterior mandibular dentoalveolar advancement utilizing lyophilized bone.
abstract: Patients with low angle Class II malocclusions complicated by strong nasal and chin profiles, interarch width discrepancies, and an exaggerated mandibular curve of Spee present several diagnostic and treatment problems. Various treatment possibilities are discussed and anterior mandibular dentoalveolar advancement is suggested as a treatment for these patients. Lyophilized, homologous bone is recommended for placement into the defects created by segmental advancement to avoid root resorption and ankylosis caused by autologous bone grafts. Finally, a modified incision is presented that facilitates watertight closure of the surgical wound.
