초록

최근 디지털 인상채득 시스템이 개발되면서 이를 기존의 CAD/CAM 시스템과 접목한 인레이, 온레이, 크라운이나 간단한 계속가공의치 등의 고정성 보철물의 제작이 활발히 소개되고 있다. 그러나 임플란트 보철에서는 주로 기존의 아날로그식 인상채득 후 이를 스캔하여 제작하는 방법이 사용되어 왔으나, 구강 내 디지털 스캔한 데이터를 이용하여 나사형 보철물을 제작하는 술식은 아직 활발히 이루어지지 않았다. 이에 본 증례보고에서는 6명의 환자를 대상으로 구강 내 스캐너인 iTero를 사용하여 디지털 스캔을시행한후그중다섯명은맞춤형지대주와 시멘트 합착 후 나사형 임플란트 보철물(screw-retained implant prosthesis after cementation, or SCRP)을 제작하였고, 임상적으로 기능과 심미적인 측면으로 만족할 만한 결과를 얻었기에 이를 보고하고자 한다.

Fixed dental prostheses such as inlay, onlay, crown, and bridge fabricated by CAD/CAM technique combined with digital impressions is getting popular due to the recent rapid progress of digital impression taking system. For the scope of implant prosthesis, however, digital intra-oral scan hasn't been actively utilized for the fabrication of superstructures. In this case report, 6 cases of titanium-milled custom abutment based on the iTero intra-oral scan data were introduced, five of them were restored with screw-type prosthesis after cementation (SCRP) and the clinical results were satisfactory on restoring the function and esthetics.
