Abstract

With the recent progress of digital technology, the computer guided surgery utilizing a guide template in the placement of implant has been actively performed, and the method employing the intraoral scanner at the implant prosthesis introduced. Fabrication method of the guide template can be largely classified into design-related rapid prototyping (RP) system and vector milling system, and each of the method has its own weakness in the clinical application despite of excellent accuracy. Thus, in this case study, a working model was fabricated by the wax RP technology using images acquired by CBCT and an intraoral scanner, and the metal bushing was picked up with orthodontic resin cast upon the wax model. Using this method, a surgical guide template was fabricated and used in surgery. From this, we could obtain a satisfactory outcome clinically in the implant placement and the fabrication of the final prostheses and thus report this case herein.

최근 디지털 기술이 발달하면서 임플란트 식립 시 가이드 템플릿을 이용하는 컴퓨터 가이드 수술이 활발하게 이루어지고 있으며, 임플란트 보철시 구강스캐너를 이용하는 방법이 소개되고 있다. 가이드 템플릿의 제작방법은 크게 RP 제작 시스템과 벡터 밀링 시스템으로 나눌 수 있는데, 각각은 우수한 정확성에도 불구하고 임상적 적용에 있어 약간의 아쉬운 점을 보이고 있다. 이에 본 증례에서는 CBCT 및 구강스캐너로 획득한 디지털 영상을 이용하여 쾌속조형법으로 왁스재료의 작업모형을 제작하고 그 위에 교정용 레진으로 금속애관을 픽업해 내는 방법을 사용하여 임플란트 수술용 가이드 템플릿을 제작하여 수술에 사용하였으며, 임상적으로 임플란트 식립 및 최종보철물 제작 시 만족스러운 결과를 얻을 수 있어서 이를 보고하고자 한다.
