초록

본 연구는 치과분야에서 가장 큰 변화를 가져온 자동화 시스템의 보급화로 CAD/CAM이 사용됨에 따라, 로스트왁스 테크닉 기법 시스템을 대체 하고 있다. 이에 따라 인상재를 이용하여 구강을 채득하는 방법에서 구강스캐너를 활용하여 디지털 데이터로 치과보철물을 제작하고 있다. 그러나 구강스캐너의 스캐닝 방법에 따라 디지털 데이터의 정밀도가 많을 영향을 받고 있는 실정이다. 이에 본 연구의 목적은 구강스캐너 (Intraoral scanner)의 스캔 작업 방법에 따라 나타날 수 있는 왜곡현상 및 데이터 정확도를 평가하고자 한다. 데스탑 3D 모형 스캐너로 임상에서 사용된 석고 모델을 이용하여 표준 스캔 데이터를 만들고 동일한 모델을 사용하여 구강스캐너로 세 가지 다른 방법의(AS그룹, ZS그룹, OS그룹) 스캔 방법으로 구분하여 각 5회씩 그룹별로 스캔 데이터를 만들었고, ZS그룹에서 0.121mm, AS그룹 0.172mm, OS그룹 0.423mm 정확도를 보여 ZS그룹에서 가장 높은 정확도를 보였고, 최대오차 값은 ZS그룹 0.113mm, AS그룹 0.169mm, OS그룹 0.246으로 최대 오차는 ZS그룹이 가장 낮고 OS그룹이 가장 높게 측정되었다. 세 가지의 스캔 방법은 정확도나 재현성에 있어 확실한 차이를 보였으며 임상에서도 역시 의미 있는 결과로 보였다.

This study was conducted to evaluate the distortion and data accuracy that may occur depending on the methods employed by the oral scanner (intra-oral scanner). Deseutap 3D models employing a plaster model used clinically as a scanner to create a standard scan data using the same model, separated by oral scanners in three different ways (AS Group, ZS group, OS group) How to scan each 5 times made the scan data for each group, it shows the 0.121 mm, 0.172 mm AS group, OS group 0.423 mm accuracy in ZS group. The ZS group showed the highest accuracy, with maximum error values of 0.113 mm, 0.169 mm and 0.246 being observed for the ZS, AS and OS group, respectively. The three scanning methods showed a clear differences in accuracy and reproducibility and also appeared to be meaningful in clinical practice.
