Abstract
Abstract Objectives To describe a multidisciplinary treatment approach that includes corticotomy, orthodontic force and orthognathic surgery for the management of skeletal Class III surgical cases. The main advantage of the combined techniques is a reduction in treatment time for young adult patients. Method Accelerated Osteogenic Orthodontics (AOO) was delivered to three young adult patients during their pre-surgical orthodontic treatment. After aligning and levelling the dental arches, a piezosurgicalcorticotomy was performed to the buccal aspect of the alveolar bone. Bone graft materials were used to cover the decorticated area and soft tissue flaps were replaced. Results The mean time for extraction space closure was 5.4 ± 1.3 months and the mean time for pre-surgical orthodontic treatment was 12.0 ± 0.9 months. The average total treatment time was 20.4 ± 2.4 months. A pre-existing bony fenestration in the buccal cortex adjacent to the right lateral incisor root apex of Case 1 was corrected. Conclusion The facial aesthetics of three patients improved following multidisciplinary treatment. This approach may be an efficient method for the orthognathic patient who desires a reduced treatment time, but further clinical research is required.

The surgical intervention to accelerate tooth movement has been described by various procedures since the 1800s,7,8 but Köle’s publication in 1959 was the first to illustrate contemporary corticotomy-facilitated orthodontics.[20]
Summary
Young adults who are diagnosed with a severe maxillomandibular discrepancy seek treatment to improve their facial and dental aesthetics in the shortest possible time.[1]. Most severe skeletal Class III patients need orthognathic surgery to correct the dysplasia. Presurgical orthodontic treatment may take 1–2 years,[2] or longer in extraction cases. Post-surgical orthodontic treatment may take 0.5–1 year,[3] which extends overall treatment time to over three years. The burden of treatment is heavy and a reduction in treatment time that still meets facial aesthetic requirements is a desirable goal. Accelerated Osteogenic Orthodontic treatment (AOO) was first introduced by Wilcko et al in 2001.4 The
