An American Board of Orthodontics case report. Correction of a severe Class II malocclusion.

Many factors often combine to create a malocclusion. Broadly these include the genetic potential of the individual and environmental or local factors. Class II, Division 1 malocclusions may result from both inherited skeletal and dental patterns and an additional environmental factor such as thumb sucking or some other habit. Successful treatment of patients with this type of malocclusion requires both an orthodontic correction of the existing dental and skeletal problems and also control of any deleterious habit. The following case report deals with a patient who had such a malocclusion.
