Periodontal accelerated osteogenic orthodontics (PAOO) is a clinical procedure that combines selective alveolar corticotomy, particulate bone grafting, and the application of orthodontic forces. This procedure is theoretically based on the bone healing pattern known as the regional acceleratory phenomenon (RAP). Recently, partial evidences supported that PAOO had some advantages: 1. Shorter treatment time; 2. An increment in alveolar bone width; 3. Decreased amount of apical root resorption; 4. Increased post-treatment stability. This article reviewed the recent case reports, clinical studies, and animal studies, and tried to introduce the development, idea, and the method of PAOO for the application of rapid orthodontics. We also tried to discuss the basis of the theory of the PAOO according to the current results of animal studies. Concluded the advantages of the PAOO, the treatment time could be shorten about one-third to oneforth, and it had less risk of root resorption. The PAOO also could increase the volume of bone, and bony support of the teeth because of using of bone grafts in combination. In addition, the stability of the outcome of the PAOO treatment would be better than the conventional treatment. These benefits could be supported by the comparing of images of CT before and after PAOO treatment and some reported animal study models. The disadvantages of PAOO included the more charge and the risk of the surgery. The flap operation may increase the risk of swelling, infection, bony ridge resorption, and gingival recession. The PAOO is not applicable for all patients, so we should carefully evaluate and select the appropriate cases, such as the candidates with the narrow arch, and not obvious abnormally anterior-posterior and transverse discrepancy of the upper and lower jaws.
