Traditionally considered as a treatment modality for the teen and adolescent, there has been in significant increase in the number of adults seeking orthodontic treatment. This increased demand for treatment has been due to changed lifestyles and increased awareness about orthodontic therapy. It is important that the orthodontist realizes that the treatment needs, clinical procedures and patient priorities for the adult orthodontic patient differ significantly from the young. While the young may seek orthodontic correction for aesthetics, the adults may prioritize treatment for restoring normal occlusal function as well as treatment efficiency and convenience. Advances in orthodontics have made treatment more comfortable and more successful than ever for people of all ages. Collaborating orthodontic treatment with other dental specialties to provide multidisciplinary dental therapy has allowed better management of the more complicated and unique requirements of the adult. This work outlines the scope, benefits, the available treatment modalities, the effectiveness and limitations of adult orthodontic treatment.
