Orthodontic approach for patients with severe periodontal disease.

Although comprehensive orthodontic treatment cannot preclude the possibility of periodontal disease developing later, it can be a useful part of the overall treatment plan for a patient who already has periodontal involvement. A careful clinical examination must determine the patient's dental health status, including any existing destruction or deficiencies of the teeth and their support, as well as the patient's ability to achieve and maintain good overall oral hygiene. Two major criteria should be considered in the treatment of these patients: (1) the patient should be seen frequently for periodontal maintenance and (2) minimal orthodontic forces should be applied.
