With an increasing number of adult patients now seeking orthodontic treatment, the problems of a dentition affected by chronic periodontitis are more likely to be encountered. Adult patients present a challenge to orthodontists because they have high esthetic demands and they often have dental conditions that may complicate treatment, such as tooth wear, poorly contoured restorations, and periodontal disease. The orthodontic treatment is a double-action procedure, regarding the periodontal tissues, which may be sometimes very meaningful in increasing the periodontal health status and sometimes maybe a harmful procedure that can be followed by several types of periodontal complications, namely, gingival recessions, bone dehiscences, gingival invaginations, and/or the formation of gingival pockets
