The objective of this study was to evaluate the effect of periodontally accelerated osteogenic orthodontics (PAOO) on gingivae and alveolar bone by analysis of clinical and cone beam computed tomography (CBCT) parameters in the treatment of 20 skeletal Class III patients. The patients included in this study were divided into test and control groups. Periodontal parameters such as probing depth (PD), gingival recession (GR), keratinized gingival width, and alveolar bone thickness of CBCT scans were measured and recorded preoperation (T0) and at 6 months postoperative (T1). The difference in PD from T0 to T1 between the two groups was not statistically significant (0.01 ± 0.46 mm vs 0.22 ± 0.65 mm, respectively; P > .05). No significant difference in GR was observed from T0 to T1 between the two groups (0.03 ± 0.26 mm vs –0.03 ± 0.27 mm, respectively; P > .05). Alveolar bone thickness (4 mm apical to the cementoenamel junction [CEJ]) change from T0 to T1 was –0.31 ± 0.35 mm for the control group and 0.06 ± 0.69 mm for the test group (P < .05). Meanwhile, alveolar bone thickness (6 mm apical to CEJ) changes from T0 to T1 were –0.38 ± 0.54 mm and 0.10 ± 0.80 mm for the control and test groups, respectively (P < .05). It was determined that PAOO in the treatment of skeletal Class III patients is effective and safe to periodontium on the basis of clinical and CBCT parameters.
