Comprehensive orthodontic treatment refers to having conventional braces, sometimes with another orthodontic appliance at the same time, when most of the permanent teeth have erupted. On average, this occurs at age 11-12. A patient who requires comprehensive treatment will only need this one stage of orthodontic treatment, which usually takes from 12 to 30 months. These patients do not have severe bite problems or crowding that require early intervention. Or they may be patients who do have a severe bite problem, like a moderate to severe overbite, who are better suited at this age when they are going through a growth spurt that will aid in the correction of their overbite.
