Abstract

Various methods have been used on patients with skeletal Class II division 1 malocclusion. The activator, Frankel appliance, headgear, Herbst appliance, and Twin-block appliance are some examples. The ideal treatment effect using these appliances would be to inhibit horizontal and vertical growth of the maxilla while promoting mandibular growth and obtaining optimum dentition. The Teuscher appliance has a simultaneous combined headgear effect with maxillary growth inhibition and an activator effect with mandibular growth promotion. The purpose of this study was to examine how well these effects were clinically obtained and the results are as follows. 1. The forward growth of the maxilla was effectively inhibited. 2. The downward-forward growth of the maxillary dentoalveolar complex was inhibited. 3. Growth promotion of the mandible was not observed. 4. The overjet, overbite, molar key were effectively improved. 5. The protruded upper lip and facial profile were unproved.

골격성 II급 1류 부정교합을 치료하는 방법으로 Activator, FR(Functional regulator), Headgear, Herbst 장치, Twin-block등의 많은 장치가 사용되어진다. 이러한 장치를 사용할 때 기대하는 가장 바람직 한 효과는 상악골의 수평적, 수직적 성장의 억제와, 하악골의 성장이 촉진되어 바람직한 골격적 관계를 가지게 되고 이러한 토대 위에 치아들이 적절하게 배열되는 것일 것이다. Teuscher장치는 Headgear의 상악골의 전하방 성장억제작용과 Activator의 하악골 성장촉진 작용을 동시에 가질 수 있도록 고안된 장치로서 실제 임상 중에 이러한 효과가 잘 구현될 수 있는지를 평가하기 위하여 성장기 남녀 각각9명(평균연령 남자 8세 11개월, 여자 9세 4개월)을 대상으로 Teuscher appliance를 평균 남아는 평균10개월, 여 아는 평균 11개월간 사용하였으며 이를 대조군과 비교 연구를 시행하였고 그 결과는 다음과 같았다. 1. 상악골의 전방 성장을 효과적으로 억제하여 주었다. 2. 상악 dentoalveolar complex의 전하방 성장을 억제하여 주었다. 3. 하악골의 전방 성장 촉진을 관찰하지 못하였다. 4. Overjet, overbite, molar key 개선에 효과적이었다. 5. 장치의 사용으로 상순의 돌출도의 개선과 안모가 향상되었다.
