Abstract

The objectives of this study was to evaluate the validity of 3D digital models made from blue LED dental scanner. Twenty same cases of stone models and 3d digital models were manufactured for this study. Intercanine distance, intermolar distance, two dental arch lengths(right, left) and two diagonal of dental arch lengths(right, left) were measured for evaluation of validity. The nonparametric Wilcoxon rank sum test was used for statistical analysis (${\alpha}$=0.05). Although stone models showed larger than digital models in all measured distances(p<0.05), none exceeded the clinically acceptable range.

본 연구의 목적은 블루 LED 기반의 치과용 스캐너를 이용하여 제작된 3차원 디지털 모형의 정확도를 평가하는 것이다. 본 연구를 위하여 20개의 동일한 석고 모형 제작 후 블루 LED기반의 치과용 스캐너를 이용하여 석고 모형과 동일한 20개의 3차원 디지털 모형을 제작하였다. 정확도를 평가하기 위해 두 집단의 모형을 대상으로 6개의 계측 거리를 지정한 후 측정하였다. 통계분석은 비모수 검정법인 윌콕슨 순위 합 검정법을 이용하여 비교 분석하였다(제1종 오류수준=0.05). 비록 모든 부위에서 디지털 모형이 석고 모형보다 작은 것으로 분석되었으나(p<0.05), 임상적 허용 수치를 벗어나지 않았다.
