CASE REPORTS ON TREATMENT OF SKELETAL CLASS III MALOCCLUSION WITH RME AND FACEMASK

급속상악확장장치와 Facemask를 이용한 골격성 III급 부정교합 환아의 치험례

The majority of Class III malocclusion have maxillary retrusion. Thus, it becomes obvious that management of most skeletal Class III malocclusion cases should include maxillary protraction as major objective. Additionally, in Class III malocclusion with posterior crossbite, RME "disarticulates" the maxilla and initiates cellular response in the sutures, allowing a more positive reaction to protraction forces. Using facemask with RME helped in correction of skeletal Class III malocclusion by the anterior displacement of maxilla and maxillary dentition, and changing the direction of the growth of mandible. Thus, acceptable improvement in the Class III profile was performed.
