Advances in the effect of periodontally accelerated osteogenic orthodontics on periodontal soft tissue
Periodontally assisted accelerated osteogenic orthodontics(PAOO)is a clinical procedure that combines selective alveolar corticotomy and particulate bone grafting.Its biological theory is based on regional acceleration phenomenon(RAP).A large number of clinical studies have shown that PAOO can shorten the orthodontic time,increase the alveolar bone thickness and reduce the risk of root resorption.However,there is no systematic review to analyze the influence of PAOO on soft tissue.The objective of this review is to evaluate the effective evidence of PAOO in improving periodontal soft tissue,and to provide reference for clinical application of this technique.
