초록

컴퓨터 지원 설계 제조 기술(CAD/CAM)의 발전에 따라, 완전한 디지털 워크플로우를 구현하기 위한 첫번째 단계인 구내스캐너의 중요성이 높아지기 시작했다. CAD/CAM 이중스캔 기술은 임시 수복물의 외형을 복제하여 최종 수복물에 반영하도록 하는 방법이다. 이 증례에서는 비심미적인 전치부, 중증도의 마모, 수직 고경의 감소를 보이는 67세 남성을 치관 연장술과 수직고경 회복을 동반한 완전구강회복을 통해 치료했다. 임시 수복물은 구내스캐너와 CAD/CAM 이중스캔을 이용해 제작되었다. 적응 기간 후, 최종 단일 구조 지르코니아 수복물을 CAD/CAM 이중스캔을 이용해 임시 수복물을 반영해 제작되었다.

With the evolution of the computer-aided design/computer-aided manufacturing (CAD/CAM) technology, the intraoral scanners are playing an increasingly important role, as they are the first step towards a completely digital workflow. The CAD/CAM double scanning technique has been used to transfer the information from provisional restorations to definitive restorations. In this case, a 67-year-old male with esthetically compromised anterior teeth, generalized severe attrition of teeth, and reduced vertical dimension was treated with full mouth rehabilitation including a re-establishment of the lost vertical dimension of occlusion assisted by the crown lengthening procedure. The provisional restorations were fabricated using an intraoral scanner and the CAD/CAM double scanning technique. After the period of adaption, the definitive monolithic zirconia restorations were delivered. The CAD/CAM double scanning technique successfully transferred the occlusal and morphological characteristics, obtained from the provisional restorations, to the definitive restorations.
