Abstract

This article describes the use of an activator with anterior high pull headgear to treat a skeletal Class II malocclusion in children in the mixed-dentition phase. A combination of headgear-activator appliance can inhibit forward and downward growth of the maxillary complex while stimulating mandibular growth. The correction of Class II malocclusion can be achieved by careful case selection of a motivated patient with a favorable growth pattern. The patients who have skeletal Class II malocclusions were treated by means of activator with anterior high pull headgear and the following results were observed; 1. Forward and downward growth of the maxillary complex were inhibited 2. Mandibular growth was stimulated and counterclockwise rotation of the mandible was observed. 3. Large overjet and deep overbite were corrected.

저자는 전남대학병원 소아치과에 내원한 혼합치열기 II급 부정교합환아를 Activator와 Anterior high pull headgear로 치료하여 다음과 같은 결론을 얻었다. 1. 상악골의 전, 하방 성장을 억제하였다. 2. 하악골의 전방 전위 및 반시계방향 회전을 유도하였다. 3. Deep overbite와 large overjet이 개선되었다.
