Abstract

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.

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.
