초록
상하악 완전 무치악 환자에서 임플란트 지지 고정성 최종 보철물을 제작할 때 환자의 수직 고경, 악간관계, 구강내에 식립된 임플란트와 임플란트에 연결된 지대주, 그리고 잇몸 형태에 관한 정확한 정보의 체득이 중요하다. 본 증례에서는 임시 보철물을 통해서 이러한 정보들을 채득하여 최종 보철물을 제작하였다. 임시 보철물을 구강 밖에서 스캔하여 스캔의 효율성을 높였고, 스캔 때 임시 보철물의 양측 후방 부위를 연결하는 스캔지그를 사용하여 스캔의 정밀도를 향상시켰다. 본 증례에서는 이와 같은 디지털 기술을 활용하여 심미적, 기능적으로 만족할 만한 임상적 결과를 얻었기에 이를 보고하는 바이다.
Abstract
When fabricating definitive implant-supported fixed prostheses in upper and lower completely edentulous patients, it is crucial to get information about the vertical dimension, jaw relationship, implants, abutments and gingival contour. In this case, temporary prostheses were used to take the information. The temporary prosthesis was scanned outside of the mouth so that it increased the efficiency of scanning it. During the scan of the prosthesis, a scan zig which connected both posterior parts of the prosthesis was used to minimize the scan errors. We report this case because we obtained satisfactory functional and esthetic results by using the digital technology.
