Maxillary protraction is the treatment of choice for growing patients with skeletal Class 3 malocclusion due to midfacial retrusion. Its treatment goal is to achieve skeletal movement of maxilla without dentoalveolar movement. To avoid dentoalveolar movement, it is necessary to enhance anchorage of maxillary dentition or to reduce resistance of maxilla protraction. The purpose of this report is to introduce two cases applying adjunctive surgical approach as intentional ankylosis and distraction osteogenesis respectively.
