Periodontally accelerated osteogenic orthodontics (PAOO): Past to present

Abstract

Different methods have been proposed and practiced to date by authors to reduce the treatment time for conventional orthodontic therapy. One of the main interdisciplinary approach to accelerate the tooth movement is the periodontally accelerated osteogenic orthodontic procedure (PAOO) introduced by the Wilcko brothers in 2001. This treatment modality has shown to reduce the overall orthodontic treatment time and has improved the post treatment outcomes. Thus, this article attempts to discuss about the historical perspectives of the treatment modality, the rationale behind the accelerated tooth movement, indications, contraindications and the modifications of this treatment approach till date.
