Abstract

Implant-assisted removable partial denture (IAPRD) can be considered as a simple and cost-effective treatment approach for an edentulous patient with anatomical or financial limitations. Recently, it was reported that the application of IARPD with implant supported fixed prostheses covered by the National Health Insurance Service (NHIS) were increasing. This case report describes the treatment of maxillary fully edentulous patient with anterior four-implant-supported fixed prosthesis and distal extension IARPD. This treatment approach may be advantageous over maxillary implant overdentures in some circumstances. The patient was satisfied with improved function and esthetics in the anterior area and financial benefit from the NHIS. Further long-term clinical studies are needed to establish clinical validity of the treatment approach described in this case report.

무치악 환자의 구강 재건을 위한 임플란트를 활용한 치료 계획으로는 임플란트 지지 고정성 가공 의치, 임플란트 피개 의치, 임플란트 보조 국소의치 등이 있으며, 각각의 방식에 대한 적응증과 장단점이 다양하다. 본 증례의 환자는 상악 국소의치의 모든 잔존 지대치의 발거가 필요했으며 후방부 잔존골이 부족하여 식립 가능한 임플란트의 개수가 한정적이었다. 따라서 골 지지가 양호한 전방부에 4개의 임플란트 식립하여 임플란트 지지 서베이드 크라운과 후방연장 임플란트 보조 국소의치로 수복해주었고 환자에게 경제적으로 효과적이면서도 심미적, 기능적으로 만족스러운 결과를 제공하였다. 상악 무치악 환자에게 이와 같은 치료 계획은 경우에 따라 임플란트 피개의치의 대안으로 사용될 수 있으며 임상적, 생역학적 유효성을 검증하기 위해 더 많은 연구가 필요하다.
