Effect on the Periodontal Phenotype of Flapless Alveolar Decortication and Augmentation During Orthodontic Treatment: A Randomized Clinical Trial

What this Trial Is About

Researchers are evaluating the effects of piezocision-assisted orthodontics combined with either soft tissue grafting or bone grafting in patients who are no longer growing. This randomized clinical trial aims to compare how these two surgical methods impact the hard and soft tissues around the teeth, particularly focusing on the periodontal phenotype and the stability of orthodontic treatment outcomes. The study also investigates treatment duration, tooth movement rates, root resorption, periodontal health, bone level changes, and patient-reported outcomes. Participants will receive orthodontic treatment with clear or metal brackets followed by one of two surgical interventions performed one week after appliance placement. One group will receive a volume-stable collagen matrix as a soft tissue graft, while the other group will receive a bone graft with a bovine xenograft covered by a native collagen membrane. Piezocision surgery involves small corticotomy cuts between tooth roots to accelerate tooth movement. After surgery, orthodontic treatment continues with regular archwire changes and follow-up visits. Throughout the study, participants will undergo extensive evaluations including scans, x-rays, periodontal examinations, and imaging to measure tissue thickness and blood flow. Monthly intraoral scans will monitor treatment progress, and patient questionnaires will capture pain levels and satisfaction. Researchers will analyze changes in tissue contours, bone and soft tissue thickness, periodontal health, orthodontic measurements, and adverse events over six months. The study expects to enroll about 40 patients and follows them through the complete orthodontic treatment period with detailed data collection and monitoring.
