Altering patient's facial profile has been a challenge over the years. Growth modification is the most effective approach to correct a jaw discrepancy because it allows patients to grow out of the skeletal disharmony. A functional appliance is one that uses the facial muscles and masticatory muscles to produce changes in the position of the individual teeth or arches. Fixed functional appliances are fixed to the upper or lower jaws for non motivated, noncompliant patients. They are well known as "noncompliant Class II correctors". They correct skeletal abnormality in young growing individuals and serve the path of correcting malocclusion.
