Abstract: Orthodontic patients are often accompanied by the change of periodontal tissue in the process of tooth movement. Due to the thin thickness of keratinized gingiva and alveolar bone plate in the labial side of the upper and lower anterior teeth, some patients may have labial buccal dehiscence or fenestration in the process of tooth movement. It even causes tooth loosening and gingival retreatment. This paper reports a case of orthodontic treatment with periodontal assisted accelerated osteogenesis for a patient with upper and lower anterior teeth with buccal bone fracture. Good bone tissue increment and stable orthodontic treatment were obtained.

Key words: periodontal accelerated osteogenic orthodontics, dehiscence, fenestration
