Periodontal-orthodontic interactions: the prevention of periodontal attachment loss in orthodontic therapy.
Periodontitis is a ubiquitous inflammatory condition resulting from the interaction between subgingival plaque, the immune system and some general risk factors. Periodontitis is a major cause of tooth loss impacting negatively upon aesthetics, speech, and mastication and has systemic inflammatory consequences. Periodontitis is treatable and treatment reduces the rates of tooth loss and improves quality of life. The pre-existing infection/ sub-gingival dysbiosis is combated by improving personal plaque control, professional prophylaxis and, if necessary, other interventions. Successful treatment necessitates sometimes orthodontic interventions in order to correct the disastrous effects of periodontal disease such as secondary tooth migrations. In order to prevent further periodontal attachment loss, anti-infective periodontal treatment is mandatory before orthodontic therapy. In many circumstances, regenerative surgical treatment of vertical defects must be performed prior orthodontics in order to assure tooth movement in a satisfactory bony bed. Several important issues concerning the interdisciplinary therapy of periodontitis patients should be considered including the role of orthodontics in the overall complex treatment of periodontitis, the possibilities and limitations of orthodontic treatment in dentitions presenting periodontal damage as well as the importance of communication between orthodontic specialist and periodontist. The huge importance of periodontal prophylaxis in the global approach of the patients benefiting by periodontal-orthodontic therapy is highlighted by recent data. Personal and professional plaque removal and control is fundamentally important to the success of periodontal therapy and to the secondary prevention of periodontal diseases. There is evidence to suggest that positive effects on periodontal status result from reinforcement of oral hygiene instructions, conscientious manual brushing, interproximal cleaning mainly with interdental brushes, or anti-plaque chemical agents delivered in a mouth rinse or dentifrice format.
