Surgical intervention to involve the alveolar housing and influence the tooth movement has been described in various forms since 19^th century. Periodontally Accelerated Osteogenic Orthodontics (PAOO) is an interdisciplinary clinical procedure that combines selective alveolar corticotomy, particulate bone grafting, and the application of orthodontic forces. This procedure facilitates faster orthodontic tooth movement and is theoretically based on the bone healing pattern known as the Regional Acceleratory Phenomenon (RAP). PAOO results in an increase in alveolar bone width, shorter treatment time, increased post treatment stability and decreased alveolar bone dehiscence. This article describes a case where PAOO technique was utilized for accelerated orthodontic closure of extraction space between maxillary right canine and second premolar in a young female with Class I malocclusion with bimaxillary protrusion.
