Abstract
The Purpose of this study was fourfold - to evaluate the general laws of friction applied to orthodontic conditions, to compare archwire materials under these controlled conditions, to compare ligation method, and to measure the effect of the artificial saliva on friction with these materials Three wire alloys (Cobalt-chromium, Nickel-titanium, Beta-titanium) in two size wires (.016" , .016"
치아에 부착된 bracket이 교정선을 따라 이동할때 필연적으로 bracket과 교정선, 결찰재 사이에 마찰력이 발생된다. 이에 저자는 동일한 bracket내에서 교정선의 종류, 결찰방법, 건조와 타액상태에 따른 마찰력 차이, 타액의 윤활제로서의 기능을 살펴보기 위해 본 연구를 시행하게 되었다. 본 실험에 사용된 bracket은 .18"
