초록

기능성 전치부 반대교합을 가진 성장기 환자의 경우, 조기에 원인을 제거함으로써 골격성으로 이행하는 것을 방지하고 성장 조절로 악골 관계를 개선함으로써 정상적인 기능과 안모를 유도할 수 있다. 1966년 R$\ddot{o}$lf Fr$\ddot{a}$nkel에 의해 소개된 Functional regulator(FR)의 한 종류인 FR III는 기능성 전치부 반대교합 및 상악의 열성장을 동반한 반대교합을 치료하기 위해 유치열기, 혼합치열기 초기, 및 영구치열기에 사용되고 있다. 이 장치는 비정상적인 근육력을 차단하여 구강 내 치열 및 악골에 대한 힘의 불균형 상태를 개선하여 정상적인 성장 발육을 할 수 있게 하는 악정형 장치이다. 이번 증례에서는 초기 혼합치열기에서 기능성 반대교합을 가진 환자의 임상 케이스를 선별하여 FR III 장치를 사용하여 다음과 같은 양호한 결과를 얻었다. 1. 초기 혼합치열기 환아에서 FR III 장치를 5~6개월 정도 단기간 장착하여 전치부 반대교합을 치료하였으며, 협측 차폐판에 의해 발생할 수 있는 상악의 횡적인 악골 변화는 나타나지 않았다. 2. 상, 하악 전치의 치성 변화와 하악의 후하방 회전의 효과를 통해 정상적인 치열관계의 회복과 심미적인 안모를 얻을 수 있었다.

In case of treating the functional type of anterior cross bite, removing the cause in early stage prevents from turning to skeletal type, leads to perform normal function, and has improved facial appearance. Functional Regulator III (FR III), one kind of the Functional regulator(FR)s suggested by R$\ddot{o}$lf Fr$\ddot{a}$nkel in 1966, applied to patients with the functional and skeletal anterior crossbite in early mixed, and permanent dentition. This appliance improves unbalanced power condition by blocking abnormal muscle-power effect, so that normal growth can be expected. In this case report, favorable results were obtained by selecting clinical cases of children in their early mixed dentition with functional cross bite. 1. FR IIIs were applied to patients with anterior crossbite for 5~6 months. Anterior crossbite patients were corrected favorably, nevertheless they didn't show any horizontal skeletal-changes by buccal shields. 2. Normal occlusion and esthetic facial contour were achieved from dental movement of maxillary and mandibular anterior teeth while the mandible rotates to posterior and inferior direction.
