Accelerated orthodontic tooth movement has received worldwide attention since the early 2000s, and many techniques have emerged ranging from minor but invasive alveolar surgery to non-invasive infrared light therapy (photobiomodulation). All accelerated tooth movement techniques depend upon a transient reduction of mineralized alveolar bone tissues (osteopenia), but none of the techniques have been shown to enhance the stability of the treatment outcome except one - Periodontally Accelerated Osteogenic Orthodontics (PAOO). The procedure includes alveolar corticotomy surgery in combination with augmentation alveolar grafting. Among the benefits of PAOO is greater stability of clinical outcomes with less relapse and increased alveolar volume with enhanced periodontal health. Mandibular dental arch stability of non-extraction PAOO patients was documented after active orthodontic treatment. In comparison to non-extraction cases without PAOO, recrowding (measured by irregularity index) at 5-years post treatment was only 0.4 mm versus 2.8 mm in the non-PAOO group. At 10-years, non-extraction PAOO recrowding was 0.9 mm versus 2.4 mm in mixed treatment (extraction & non-extraction) cases without PAOO. In a separate article, data were extracted from a comprehensive literature review that included 1056 premolar extraction cases and 886 non-extraction cases. At 10-years, the PAOO change (0.9 mm) was twice stable than without PAOO therapy in extraction cases (2.0 mm) and non-extraction cases (1.8 mm). Surprisingly stable was intercanine width that increased after PAOO therapy by 1.8 mm and continued to increase an additional 0.2 mm during the 5-year period after active orthodontic treatment. By 10-years, intercanine width was still greater than the pretreatment width by 0.5 mm whereas all other groups to which PAOO was compared had decreased in intercanine width. In conclusion, augmented corticotomy technique (PAOO) is the only active orthodontic treatment strategy reported to date, that stabilizes the mandibular anterior segment and reduces irregularity index and intercanine width instability.
