성장기중 Face Mask를 이용한 Angle씨 III급 반대교합 해소의 치험례

A CASE REPORT ON TREATMENT OF GROWING ANGLE'S CLASS III ANTERIOR CROSSBITE BY FACE MASK

Face mask is an extraoral appliance which used to protract maxilla, and can help in the correction of moderately severe class IlI malocclusions by the anterior displacement of the maxilla and maxillary dentition, and possibly restricting or changing the direction of the growth of the mandible. In three cases the results were followed. 1. Anterior crossbite was corrected 2. Maxilla & maxillary dentition were displaced forwardly. 3. Lingual tipping of the mandibular incisors, and backward & downward rotation of mandible were performed. 4. Acceptable improvement in the class III profile was performed.
