The effects of orthodontic treatment on periodontal tissues in patients with reduced periodontal support

摘要: The effects of orthodontic treatment on periodontal tissues in patients with severely reduced support were studied. A prerequisite for tooth movement was a reduction inflammation by regular scaling and high standard oral hygiene. Surgical elimination deepened pockets not performed before movement. 20 took part the study. maxillary overjet light forces elastics from removable appliances. Oral hygiene, gingival inflammation, pocket depth alveolar bone level recorded hygiene after treatment. As result treatment, Plaque Index Gingival scores markedly reduced. values showed no major change. When comparing mean proximal measurements difference could be seen. individual remained unchanged every second surface. maximum deterioration level, measured as percentage length, during 10% 9 surfaces out 142. Provided careful preorthodontic existing advanced disease is given are kept within physiological limits, results this clinical study show that increased progression marginal periodontitis will occur due to
