Updates on periodontally accelerated osteogenic orthodontics

Abstract

ABSTRACT Purpose: The objective of this review was to investigate the recent reports on periodontally accelerated osteogenic orthodontics (PAOO) in major orthodontic journals in order to summarize the relevant updates and clinical findings. Materials and methods: The PubMed database was searched for PAOO-related articles published in The American Journal of Orthodontics and Dentofacial Orthopaedics (AJO-DO), The Angle Orthodontists (AO), The European Journal of Orthodontics (EJO), The International Journal of Oral and Maxillofacial Surgery (IJOMS), The Australian Orthodontic Journal (AOJ) and other major orthodontic journals. Keywords used for searching were corticotomy, PAOO, piezocision and micro-osteoperforations (MOPs). Based on the information from the titles and abstracts, relevant articles on PAOO were selected and analysed. Results: As an alternative surgical method, the PAOO technique can accelerate adult patients’ tooth movement and shorten the treatment time. Compared with conventional orthodontic treatment, the PAOO technique shows advantages in terms of treatment cycle and treatment effect. Currently, scholars tend to believe that the PAOO technique does not increase the risk of root resorption, periodontium injury, and alveolar bone defect. Conclusions: Long-term efficacy of PAOO lacks randomized controlled clinical trials. However, with the deepening of research, PAOO – a relatively mature means of accelerating tooth movement – is likely to be more attractive in orthodontic treatment.
