초록
한국인에 적합한 preadjusted bracket을 개발하기 위하여 한국인 성인 정상 교합자 14명을 대상으로 crown angulation, inclination, in and out, molar offset angle을 구했다. 정상 교합자 14명의 cast를 3차원 스케닝한 후 스케닝한 모델을 대상으로 컴퓨터 프로그램을 이용하여 측정하였다. 이는 기존의 모델을 직접 수작업으로 측정할 때보다 정확하고 빨리 측정할 수 있었다. 다음과 같은 결론을 얻었다. 1. 한국인 정상교합자의 각 치아의 치축 경사(angulation), 치관 경사도(inclination), in and out, molar offset angle을 구하였다. 2. 3차원 스케너와 컴퓨터를 이용하여 측정하였기 때문에 보다 정확하고, 빠르게 측정할 수 있었다.
The objects of this study were to analyze the crown angulation, crown inclination, molar offset angle, and crown in and out of the Korean adults having normal occlusion. 14 subjects (7 male, 7 female) were chosen in the 80 subjects who had ideal occlusion and beautiful profile we thought. The casts were obtained from the subjects, and then they were scanned with 3-dimensional scanner machine. We analyzed them with computer program based upon Andrews methods and the following results were obtained. 1. We got the norm of the crown angulation, crown inclination, molar offset angle, and crown in and out in the Korean adults. 2. The analysis using 3 dimensional scanner and computer program was more fast and accurate than the manual methods.
