초록
본 연구는 교정 치료 동안 교정용 호선의 굵기가 교합력에 미치는 영향을 알아보고, 인공 식괴인 실리콘블록 교합 시 교합력의 차이가 있는지를 확인하기 위해 시도되었다. 실험 모델로 사용한 타이포돈트는 제1 소구치를 발치한 형태로, 각 치아는 실리콘 인상재로 치주 인대를 재현하였고, 브라켓을 간접 부착술로 접착하였다. 모형의 구치부 치아들 설측에 스트레인 게이지를 부착하였다. 다양한 두께의 스테인레스 스틸 호선을 삽입한 상태에서 만능물성시험기로 200 N의 압축력을 가하여 치아별로 각각의 교합력을 측정하였고, 5 mm 두께의 실리콘 블록을 제작하여 구치부 교합면에 위치시킨 후 동일한 실험을 실행하였다. 각 실험을 10 회씩 반복하였다. 호선의 굵기가 커질수록 제2소구치에서 교합력은 증가, 제1대구치와 제2대구치에서 교합력은 감소하였다. 세 개의 구치부 치아들에 가해지는 교합력의 합은 감소하였다. 실리콘 블록 교합 시 저작물이 놓이는 최후방치아의 교합력이 가장 크게 나타났다. 이상의 연구를 통해 교합 시 호선이 굵어질수록 전방치아로 교합력이 스플린팅되는 효과를 나타냄을 알 수 있었다. 또한 너무 굵은 호선은 임상에서 사용 시신중하게 고려되어야 하며, 음식물 저작 시 접번 운동에 의해 최후방구치에 가장 큰 교합력이 집중되었음을알 수 있었다.
Abstract
This study investigated the effect of wire diameter on the occlusal force by measuring the occlusal force when varied wire diameter was applied. The difference of the occlusal force was also determined by measuring the occlusal force with silicone and without a block. The typodont used in this study had the first premolar extracted, the periodontal ligament was imitated with silicone impression materials and .018˝ metal brackets were passively bonded. Strain gauges were attached to the palatal surface of the upper left second premolar, first molar, and second molar. A Universal Testing Machine was used to apply a compressive force of 200 N and occlusal force was measured. Next, after a 5 mm thick silicon block was placed on the upper left second premolar, first molar and second molar, the same investigation was repeated. Each test was conducted ten times. The occlusal force of the upper second premolar was increased and that of the upper first molar and second molar was decreased on occlusion as the wire diameter was increased. The sum of the occlusal forces was decreased as the wire diameter was increased. The occlusal force of the most posterior teeth was the largest when biting the silicon block. In conclusion, the splinting effect of the occlusal force towards the anterior teeth was demonstrated on occlusion as the wire diameter was increased, and the use of the large wire should be considered discreetly. The occlusal force of the most posterior teeth was the largest when biting the silicon block due to the hinge movement of the mandible.
