[Correlations of orthodontics and periodontics].

Periodontics and orthodontics are correlated with one other in many ways. For instance, periodontal conditions have to be considered in the orthodontic treatment of adults, special orthodontic measures are taken to enhance a periodontal treatment, and when periodontal surgery is performed for the prevention of relapse or the disimpaction of teeth. Dental practitioners working in the field of orthodontics should have a sound understanding of the biology and pathology of the periodontium in order to avoid causing periodontal lesions, or when lesions are present, how best to determine prognosis and differential treatment.
