摘　　要：BACKGROUND Maxillofacial deformities are skeletal discrepancies that cause occlusal,functional,and esthetic problems,and are managed by multi-disciplinary treatment,including careful orthodontic,surgical,and periodontal evaluations.However,thin periodontal phenotype is often overlooked although it affects the therapeutic outcome.Gingival augmentation and periodontal accelerated osteogenic orthodontics(PAOO)can effectively modify the periodontal phenotype and improve treatment outcome.We describe the multi-disciplinary approaches used to manage a case of skeletal ClassⅢmalocclusion and facial asymmetry,with thin periodontal phenotype limiting the correction of deformity.CASE SUMMARY A patient with facial asymmetry and weakness in chewing had been treated with orthodontic camouflage,but the treatment outcome was not satisfactory.After examination,gingiva augmentation and PAOO were performed to increase the volume of both the gingiva and the alveolar bone to allow further tooth movement.After orthodontic decompensation,double-jaw surgery was performed to reposition the maxilla-mandibular complex.Finally,implant placement and chin molding were performed to restore the dentition and to improve the skeletal profile.The appearance and function were significantly improved,and the periodontal tissue remained healthy and stable.CONCLUSION In patients with dentofacial deformities and a thin periodontal phenotype,multi-disciplinary treatment that includes PAOO could be effective,and could improve both the quality and safety of orthodontic-orthognathic therapy.
