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.

Corticotomy-assisted orthodontics (CAOT) can shorten orthodontic treatment time by increasing regional acceleratory phenomenon. The periodontal wound healing caused by corticotomy are similar to the periodontal tissue reaction induced by orthodontic force; if the two phenomena could be accumulated and both enhancing bone remodeling, orthodontic tooth movement should be accelerated theoretically. There are many different kinds of procedures and strategies in the clinical application of corticotomy-assisted orthodontics, but when the cost and benefit ratio for the patients are thoroughly considered, using minimal invasive corticotomy to assist orthodontic treatment may be more practical. As for the clinical efficacy of minimal invasive corticotomy, …
