There are many reasons for adult orthodontic treatment. Treatment can be comprehensive or limited to specific issues. The process of tooth movement is identical to treatment of children with the only limitation being the lack of growth. Some patients need comprehensive treatment and are treated for the first time as adults, where others have revision needs.
Revisions can be needed due to relapse, shifting due to tooth loss, crowding associated with aging or a variety of other situations. Sometimes orthodontics is needed in conjunction with periodontal treatment or in preparation for restorative treatment (implant and bridges). Also, orthodontics is frequently the most effective way to correct problems with the temporomandibular (jaw) joints.
