Periodontal disease is a multibacterial infection causing the host’s immune response destructive to the supporting structures of teeth. Many behavioural, genetic or environmental risk factors, such as nicotine dependence, influence the development of periodontal disease. The factors modify the immune response, which leads to more serious consequences of the disease. Currently, orthodontic treatment is more and more often applied as part of an interdisciplinary approach to an adult patient aged over 50. The aim of the study was to present interdisciplinary treatment, including advanced orthodontic techniques, of an adult patient manifesting advanced periodontal disease. During the orthodontic treatment for which some subtle forces were applied, no resorption of the burdened teeth was observed as evidenced by the lack of statistically significant differences when the pre-treatment T1 measurement is compared to T2 made just before the appliances were removed. To sum up, orthodontic techniques can be successfully used in patients with advanced, chronic, general periodontal disease on condition that the patient’s oral hygiene is good, the active phase of the periodontal disease is in remission and the patients have their teeth regularly cleaned by a professional.
