This case report documents the first use of particulate autogenous bone graft with the corticotomy-assisted rapid orthodontic procedure known as periodontally accelerated osteogenic orthodontics (PAOO). A 41-year-old man, with class II, division 2 crowded occlusion, was treated with the PAOO procedure. Buccal mucoperiosteal flaps were reflected, and selected vertical and horizontal corticotomy was performed around the roots in both the maxillary and mandibular arches. Particulate bone graft was harvested from the rami and exostosis for alveolar ridge augmentation. Orthodontic movement was initiated immediately after the surgical intervention and adjusted every 2 weeks. Eight months after corticotomy surgery, total active orthodontic treatment was completed. No detrimental periodontal effects or root resorption were observed. The alveolar ridges of both the maxilla and mandible maintained the original thickness and configuration despite facial tipping of the incisors. It was concluded that PAOO is an effective treatment approach in adults to decrease treatment time and reduce the risk of root resorption. Selected corticotomy limited to the buccal and labial aspects also significantly reduces treatment time. More clinical studies with additional patients and long-term follow-up are needed to determine the optimal amount of autogenous bone graft.
