Abstract

When restoring with a dental digital system for implant-supported prosthesis, a double digital scanning technique is required: an intraoral scan of the three-dimensional implant location and intraoral scan after placement of temporary denture or provisional prosthesis. During the intraoral scan, the use of scan body as a stable landmark can improve the accuracy of digital impression and simplify laboratory process. In this case, a full-digital system was used to plan and fabricate a custom abutment, provisional prosthesis, and definitive prosthesis. After implant placement, the scan area of the intraoral scan body connected with implant and the intraoral scan body marked on the inside of temporary denture were superimposed. Out of the superimposed files, a custom abutment and provisional prosthesis were fabricated which match the vertical dimension of temporary denture, and definitive prosthesis was fabricated based on provisional prosthesis. We report this case because result has been functionally and esthetically satisfactory by using vertical dimension and central relation set during the fabrication of temporary denture to the definitive prosthesis.

임플란트 고정성 보철물 제작 시 디지털 시스템을 이용하여 수복할 때, 3차원적인 임플란트 위치의 구내 스캔과 임시 의치 혹은 임시 보철물 장착 후 구내 스캔을 이용한 이중 디지털 스캐닝(double digital scanning) 기법이 필요하다. 구내 스캔 시, 스캔 바디를 안정적인 랜드마크로 이용하면 다지털 인상의 정확도 향상과 기공과정이 효율적이고 단순화될 수 있다. 본 증례는 완전 디지털 시스템을 활용하여 맞춤형 치과용 임플란트 지대주 및 임시 보철물, 최종 보철물을 계획하고 제작하였다. 임플란트 식립 후, 임플란트에 체결한 구내 스캔 바디와 임시 의치 조직면에 인기 된 구내 스캔 바디의 스캔 영역을 중첩하였다. 중첩된 파일에서 임시 의치의 수직 고경에 맞는 맞춤형 치과용 임플란트 지대주와 임시 보철물을 제작하여 환자에게 시적 하였고, 임시 보철물을 토대로 최종 보철물을 제작하였다. 임시 의치 제작 시 설정한 수직 고경, 중심위 등을 최종 보철물까지 활용하여 기능 및 심미적으로 만족할 만한 결과를 얻어 이를 보고하고자 한다.
