Abstract

In edentulous patients, implant - supported fixed prosthesis treatment has been proved to be useful, but involves complex treatment process. On the other hand, in the modern dentistry, digital technology has been developed day by day and it has expanded its range to the implant restoration of edentulous patients. In this case, a digital system was used for all stages of diagnosis, surgery, design and fabrication of provisional implants fixed prosthesis restoration in 66-year-old mandibular edentulous patients. In the preoperative diagnosis stage, a provisional restoration was designed based on the mucosal scan using the intraoral scanner and the stable occlusion of prefabricated complete denture of the patient. After flapless implant surgery using the surgical guide, the prefabricated interim restoration was connected to the implant and used as immediate provisional restoration. The final restoration was designed and fabricated by transferring the vertical dimension and the centric relation of the provisional restoration with stable occlusion using digital technology. We report a simple protocol of implant treatment in edentulous patients by using digital techniques to preserve the patient's vertical dimension and occlusion.

무치악 환자에게 임플란트 지지 고정성 보철수복 치료는 그 효용성이 검증되었으나, 복잡한 치료과정이 수반된다. 반면, 현대 치의학에서 디지털 기술력은 나날이 발전하여 현재 무치악 환자의 임플란트 수복치료까지 그 범위를 확장하였다. 본 증례에서는 66세 하악 무치악 환자의 임플란트 고정성 보철 수복에 대하여 진단부터 수술, 임시수복물 및 최종수복물의 디자인과 제작까지 디지털 시스템을 모든 단계에 이용하였다. 수술 전 진단단계에서 구강스캐너를 이용한 점막스캔과 환자의 안정적인 기존 총의치 교합을 토대로 임시수복물을 디자인하였다. 수술가이드를 이용하여 무절개 임플란트 식립 후에 사전제작한 임시수복물을 임플란트와 연결하여 즉시 임시수복물로써 사용하였다. 디지털 기술을 이용하여 안정적인 교합이 형성된 임시수복물의 수직고경과 중심위를 이전하여 최종수복물을 디자인 및 제작 하였다. 디지털 기술을 활용하여 환자의 수직고경과 교합을 보전하는 방법을 사용함으로써 무치악환자에서 복잡할 수 있는 임플란트 치료의 간단한 프로토콜을 정립하였기에 보고하는 바이다.
