본 연구는 성장기 II급 부정교합자를 골격 형태에 따라 분류하여 액티베이터 사용 효과를 비교, 분석하고 그 결과를 진단, 치료 계획 수립 등 임상 과정에 연계시키기 위해 시행되었다. 실험은 수완부 방사선 사진상 Fishman 분류의 2, 3, 4 단계로 최대성장기 이전의 II급 부정교합자를 대상으로 하였다. 대조군은 ANB 3도 이상이며 악정형 장치 치료를 받지 않고 치열교정 치료만 받은 환자로 총 25명(남자 15명, 여자 10명)이고 실험군은 액티베이터 치료를 받은 환자로 총 116명(남자 53명, 여자 63명)이었다. Articular angle과 gonial angle을 이용하여 골격 형태를 hyperdivergent type과 hypodivergent type으로 분류하여 액티베이터 치료효과를 비교한 결과 hypodivergent한 골격 형태를 가진 환자에서 더 큰 효과를 보였다. 따라서 성장기 II급 부정교합자의 진단과 치료계획 수립 시 안모의 골격 형태 분류를 통해 액티베이터의 효과를 예측할 수 있다고 생각한다.

Abstract
Objective: To establish proper diagnosis and treatment plan for skeletal Class II malocclusions, some important factors to consider are the patient's skeletal morphology, prognosis as well as the treatment effects. Therefore, the present study analyzed the effects of activator treatment on different skeletal patterns in growing Class II malocclusion patients. Methods: A total of 116 patients (53 boys & 63 girls) in the experimental group were treated with the activator appliance. The experimental group was classified into either hyperdivergent or hypodivergent groups according to articular and gonial angles. Results: Patients with hypodivergent growth patterns showed good effects of activator treatment. Conclusion: It seems conceivable that through classifying adolescent Class II malocclusion patients into different skeletal patterns, activator treatment effects may be predicted during the diagnosis and treatment planning stage.
