Two New Modalities for maxillary Protraction Therapy: Intentional Ankylosis and Distraction Osteogenesis

상악 전방견인치료의 새로운 두 가지 기법: Intentional Ankylosis와 Distraction Osteogenesis

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.
