Severe periodontitis and orthodontics: How far should we go?

Severe forms of periodontitis can often result in pathological tooth migration. In such cases, orthodontic realignment is an indispensable complement to periodontal management. However, in some cases involving very advanced periodontal destruction, the question arises as to the limits of conservative treatment. Are the results of orthodontic periodontic treatment stable over time? All orthodontic treatment must be preceded by reduction of the inflammation. This paper uses clinical cases to illustrate each step to be followed in the periodontal therapeutic process in order to achieve successful orthodontic-periodontal treatment from etiologic therapy to surgical decontamination and long-term periodontal follow-up.
