This is a case of a 51 years old female with skeletal Class I malocclusion, suffered from root fracture of #46 & moderate generalized periodontitis. She asked for molar protraction of #47 #48 to close the extraction space of #46 without any prosthesis or dramatic change of profile. Treatment planning was removal of #46 & protraction of #47 #48 with mini screw. It became difficult to close the residual space of #46 after 17 months of treatment due to narrow edentulous ridge. Therefore corticotomy plus bone grafting was performed. After treatment, her occlusion was stable and profile was satisfied. Selective alveolar corticotomy can be a feasible treatment modality for adults. The procedure not only enhances the efficiency of treatment but also broadens the range of tooth movement.
