Abstract
Orthodontic treatment combined with alveolar corticotomy plus augmentation grafting is a technique known as Periodontally Accelerated Osteogenic Orthodontics (PAOO) or Wilckodontics. Benefits of PAOO include: 1) orthodontic treatment times 3X to 4X more rapid, 2) enhanced scope of malocclusion treatment, including a reduction of extractions and/or orthognathic surgery, 3) greater stability of clinical outcomes and less relapse, and 4) increase alveolar volume and enhanced periodontal health. The focus of the presentation is on recently published data demonstrating significantly greater stability of the mandibular incisors 5-years and 10-years after orthodontic treatment. Overview: Long term stability: A consensus in orthodontic literature indicates that the mandibular anterior segment will increase in crowding. This is true whether or not crowding was previously eliminated with orthodontic treatment. Our research demonstrates that PAOO therapy results in significantly greater stability following orthodontic treatment at 5-year and at 10-years using irregularity index in order to quantify mandibular anterior crowding. Re-crowding of mandibular incisors at 5-years was 1.5 mm for PAOO and 4.3 mm for control; at 10-years the comparism was 2.1 VS 4.5 mm, respectively. Increased mandibular anterior stability of orthodontic outcomes following PAOO is likely due to high tissue turnover induced by decortication as well as the thicker cortical bone resulting from the augmentation grafting.
