초록

장기간 사용된 임플란트 피개의치는 부착장치의 마모와 전치부 교합집중, 인공치 파절, 의치의 회전 등을 보일 수 있다. 이러한 문제점은 추가적인 임플란트 식립을 이용한 임플란트보조 국소의치(IARPD, implant assisted removable partial denture)로의 전환으로 개선할 수 있다. 본 증례는 임플란트 피개의치를 사용하는 3급 악간관계 환자에서 전치부에 집중된 교합을 분산하고 의치의 회전방지를 위해 서베이드 크라운을 이용한 IARPD으로 전환하였다. 여러 단계의 임시수복물을 통해 적절한 기능과 심미를 가진 최종보철물의 형태를 결정하였으며 최종 보철물의 적절한 구치부 교합과 임플란트 주위 변연골 유지를 보였기에 이를 보고하는 바이다.

The long-term use of an implant overdenture shows problems, such as wear of attachment, concentrated occlusal forces on the anterior teeth, fracture of artificial teeth and rotation of denture. By transitioning to an Implant-assisted removable partial denture (IARPD) using additional implant placement, the problems can be solved. In this case report, a transition was made from implant overdenture to IARPD utilizing surveyed crowns to distribute occlusal forces concentrated on anterior teeth and to prevent denture rotation in a skeletal Class III patient. Design of definitive prosthesis with appropriate function and aesthetics was determined through several stages of provisional restorations. In this case, appropriate posterior occlusion and maintenance of peri-implant bone level of definitive prosthesis were observed.
