Laser Biostimulation and Self Ligating Appliances in Orthodontics: Periodontal Remodeling:

摘要

24 patients are selected and 30 teeth in vestibular mucosae, without keratinized gingiva. No active periodontal disease (no BOP and gingival recessions). No BOP and CAL loss at the start of the orthodontic treatment. Every patient was treated with self ligating appliances (Time2/Time3, American Orthodontics). In every orthodontic session (each 30 days as average) the patient was treated with Nd: Yag laser biostimulation, for 90 seconds, with 320 micron fiber section, on utilizing the Biostimulating machine paremeters. No termical effects were produced by lasers applications. At the moment of debonding, 30 teeth involved in the research were evaluated in terms of quality and quantity of attached gingiva. BOP and CAL loss were also investigated. Every tooth considerated, at the end of orthodontic treatment showed a attached gingiva around the crown: the average of keratinized gingiva at the end of the study was 2,7 mm and the mean increasing at each month was 0,45 mm. The combination between self ligating appliances and laser's biostimulation could improve the differentiation of periodontal ligaments stem cells in fibroblasts, able to promote attached gingiva around the crown of the teeth erupted in oral vestibular mucosae.
