Abstract

Fixed implant prostheses or removable partial dentures are common treatment for partially dentulous patients. Recently, an implant-assisted removable partial denture (IARPD) has been introduced and is widely used. In the case of removable partial dentures using implant attachment and surveyed fixed prostheses, the consideration about parallelism of insertion path between implants and surveyed fixed prostheses is an important factor for success of IARPDs. In this case, she complained of discomfort while using the mandibular removable partial denture. Thus, an IARPD using implant surveyed fixed prostheses was fabricated. Thereafter, more implants were placed by a digital guide surgery to have the same insertion path as the existing surveyed fixed prostheses. Locator attachments were installed to the left and right premolar implants, and the left molar was able to obtain support of the removable partial denture with healing abutment. The clinical results were satisfactory on the aspect of aesthetic and masticatory function.

다수 치아가 상실된 부분 무치악 환자에서 고정성 임플란트 보철, 가철성 국소의치를 이용한 치료와 더불어 최근에는 임플란트를 보조적으로 이용한 임플란트 융합 국소의치 또한 많이 이용되고 있다. 이중 부착 장치와 서베이드 고정성 보철물을 함께 이용하는 임플란트 융합 국소의치의 경우, 부착 장치와 국소의치가 동일한 삽입로를 가지도록 하는 것이 중요하다. 본 증례의 환자는 하악 국소의치를 사용하던 중, 불편감을 주소로 내원하여 임플란트 서베이드 고정성 보철물을 활용한 임플란트 융합 국소의치를 제작하였다. 이후 추가적인 임플란트 식립 시, 기존의 임플란트 서베이드 고정성 보철물의 삽입로와 동일한 식립 방향을 설정하기 위하여 디지털 가이드 수술을 이용하였다. 임플란트 식립 후, 좌, 우측 소구치부에는 로케이터를 장착하고, 좌측 구치부에는 치유 지대주 상태로 국소의치의 지지를 부여하여 제작하였다. 이를 통해 심미적, 기능적으로 만족할 만한 결과를 얻었기에 보고하는 바이다.
