[Periodontally accelerated osteogenic orthodontics in clinical treatment].

Orthodontic tooth movement inevitably affects adjacent periodontal tissue. The labiobuccal alveolar bone is generally thin, and patients with dental crowding often present alveolar dehiscence and fenestration. These may lead to prolonged treatment time, even gingival atrophy, tooth loosening and other complications in the orthodontic tooth movement. Periodontally accelerated osteogenic orthodontics (PAOO) could accelerate the orthodontic tooth movement and promote the formation of new bone by using corticotomy and bone grafting. This article, starting from the influence of orthodontic treatment on periodontal hard tissue, describes the application of PAOO in orthodontic treatment.
