Abstract

The implant-supported fixed dental prosthesis in irradiated maxilla needs meticulous treatment planning due to low bone healing capacity. All-on-4 concept implantation can reduce the number of implants to be placed avoiding bone grafting procedure. Conventionally, prefabricated angled abutments for tilted implants have been used. However, in this case, it was replaced with computer-aided design and computer-aided manufacturing (CAD/CAM) abutment. This case report described all-on-4 concept implantation and fabrication of CAD/CAM zirconia fixed dental prostheses using CAD/CAM titanium abutments.

방사선치료를 받은 상악에 임플란트 지지 고정성 보철물을 이용하여 수복하는 것은 골치유능력이 낮기 때문에 상세한 치료계획이 필요하다. All-on-4 개념에 의한 임플란트 식립은 골이식을 피하면서 임플란트를 매식할 수 있어 유리하다. 일반적으로 경사된 임플란트에는 기성 경사형 지대주를 사용해왔다. 본 임상증례에서는 computer-aided design and computer-aided manufacturing (CAD/CAM)으로 제작된 지대주를 사용하였다. 본 증례는 all-on-4 개념에 의해 임플란트를 매식하고 CAD/CAM titanium 지대주를 제작한 다음 CAD/CAM zirconia 고정성 보철물로 수복하여 좋은 결과를 얻었기에 보고하고자 한다.
