Orthodontic treatment (OT) has become a means of improving psychosocial well-being secondarily to enhanced occlusal function and can help patients obtain normal oral physiologic function, coordinated facial profiles, and healthy dentomaxillofacial development. With more adult patients undergoing OT, the need for interdisciplinary treatment and collaboration is vital to ensure periodontal health. This article highlights the importance of combined efforts between periodontics and orthodontics in adult patients with a history of periodontitis who are interested in OT. Furthermore, the article discusses the technological and surgical advances within these specialties, as well as timing of synchronization of treatment. A clinical case demonstrates the results of a collaborative periodontics and orthodontics approach to treat an adult patient with a history of advanced periodontal disease.
