Cone beam computed tomography of bone dimensions in periodontally accelerated osteogenic orthodontics: A retrospective study

With an improved awareness of dental esthetics and function, an increased number of adult individuals are seeking orthodontic therapy. Adult patients present with unique challenges for the treating orthodontist such as extensive restorative work, missing teeth, thin alveolar bone, and thin gingival tissues. This might result in increased recession, bone loss and fenestration, and dehiscence. Periodontally accelerated osteogenic orthodontics (PAOO) allows for quicker tooth movement, as well as increasing alveolar bone thickness to prevent subsequent hard and soft tissue deficiencies. In this retrospective study, we compared the effects of orthodontic treatment completed with and without PAOO on alveolar bone thickness. Our findings demonstrated increased bone thickness and a decrease in the incidence of fenestration and dehiscence in the PAOO group. The crestal bone height remained the same on the buccal, but there was a significant loss of vertical bone on the palatal side of the root in the PAOO group. Trends were seen of more tooth movement in the PAOO group and a reduction in treatment time. Further research is needed to reduce sample inconsistency and standardize the PAOO technique.
