초록
본 논문은 기존에 선행되었던 연구들을 바탕으로 디지털 모형의 정확도를 평가하는 여러 가지 방법에 관하여 정리하였다. 디지털 모형의 정확도 평가 시, 시험자 교육과 인공적 지표의 사용을 통해 오차를 줄일 수 있다. 디지털 치아 모형의 정확도 평가법은 크게 선형 측정법, 2차원 단면 분석법, 3차원 최적합 분석법으로 분류할 수 있다. 스캐너의 기술이 발전함에 따라 디지털 인상 기술과 전통적 인상법의 정확도를 비교하는 많은 연구들이 이루어지고 있다. 다양한 방법을 이용하여 디지털 모형의 정확도를 평가할 수 있으며, 앞으로 스캐너의 기술 향상 및 3차원 모형 분석 소프트웨어의 개발에 따라 디지털 모형의 정확도 평가 방법이 더욱 효과적으로 변화할 것이라 생각된다. 이 논문에서는 디지털 모형의 정확도를 평가하는 방법들에 대해 소개하고, 각각의 상황에 따른 효과적인 정확도 분석법에 대해 알아보고자 한다.
Abstract
The aim of this article was to review various methods used to evaluate the accuracy of digital dental models. When evaluating the accuracy of digital models, the errors can be reduced by educating examiners and using artificial landmarks. The accuracy evaluation methods of digital dental models are divided into linear measurement, 2-dimensional cross-sectional analysis, and 3-dimensional best fit measurement. As the technology of scanners develops, many studies have been conducted to compare the accuracy of digital impression and conventional impression. According to improvement of scan technologies and development of 3-dimensional model analysis software, the ability to evaluate the accuracy of digital models is becoming more efficient. In this article, we describe the methods for evaluating the accuracy of a digital model and investigate effective accuracy analysis methods for each situation.
