Periodontic-orthodontic interactions—rationale, sequence and clinical implications

Abstract

Periodontic-orthodontic interactions are mutually beneficial. Combined periodontic and orthodontic treatment can greatly enhance periodontal health and dentofacial esthetics. Adjunctive orthodontic management of pathological tooth migration has unique effects in subjects with moderate to advanced periodontitis. Orthodontic treatment should only be undertaken with healthy periodontium or healthy periodontium with reduced height, and oral hygiene instruction and regular periodontal care are essential during orthodontic tooth movement. Conversely, appropriate adjunctive periodontal procedures may facilitate orthodontic treatment in selected subjects. A predictable treatment outcome needs coordination of care between the two disciplines along with appropriate risk assessment. Successful treatment and its long-term maintenance can be achieved through close collaboration between the periodontist and orthodontist.
