The Effect of Periodontally Accelerated Osteogenic Orthodontics on Periodontal Phenotypes in Adult Patients With Skeletal Class II Malocclusion: A Retrospective Cohort Study

Traditional orthodontics presents substantial periodontal risks in the mandibular anterior region for patients with skeletal Class II malocclusion. Our study found that PAOO attenuates the detrimental periodontal consequences associated with conventional orthodontics, including keratinized tissue thinning, width reduction, and alveolar bone loss in the mandibular anterior region. Notably, the therapeutic superiority of PAOO was particularly evident in patients presenting with thin gingiva biotype or severe bone defects. These findings provide valuable evidence for developing interdisciplinary periodontal-orthodontic treatment strategies in skeletal Class II malocclusion cases.
