Abstract

Due to the increasing number of adult patients seeking orthodontic treatment, there is always a need to look for ways to accelerate tooth movement. Periodontally accelerated osteogenic orthodontics (PAOO) is a clinical procedure that combines alveolar bone corticotomy, particulate bone grafting and the application of orthodontic forces. This procedure is based on bone healing pattern known as the regional acceleratory phenomenon. This procedure results in an increase in alveolar bone width, shorter treatment time, increased post treatment stability and decreased amount of apical root resorption. Tooth movement can be enhanced, and cases completed with increased alveolar volume providing for a more intact periodontium, decreased need for extractions, degree of facial remodeling and increased bone support for teeth and soft tissues, thereby augmenting gingival and facial esthetics. The purpose of this article is to describe the history, biology, surgical techniques, advances, advantages, disadvantages and possible complications of the PAOO procedure.
