Abstract

Growth modification by using removable orthopedic appliances has been commonly used in growing patients to correct maxilla-mandibular jaw discrepancy. Previous studies reported the different effects of various orthopedic appliances on the airway dimension. Low-pull headgear therapy may induce a short-term decrease of the upper airway dimension in Class II patients. Face mask therapy seems to be associated with the increase of upper airway dimension in growing Class III patients. However, mandible protruding appliances can increase the upper airway dimension, especially in the Class II patients with mandible retrusion.
