Abstract

Implant prostheses and removable partial dentures are mainly used as treatment methods for partial edentulous patients who have lost a number of teeth. The implant-assisted removable partial denture (IARPD) is strategically selected. The defect in maxillofacial structure due to osteomyelitis, a type of facial bone infection, causes dysfunction such as mastication, swallowing, and pronunciation, as well as social and psychological effects, so a removable restoration is required to restore the supporting tissue. Design of abutment and partial dentures is an essential factor in the success of treatment. In this case, IARPD, which has superior retention and stability compared to traditional removable partial dentures, can have a good prognosis. In a partial edentulous patient with bone defects due to osteomyelitis treatment, the stability of the denture was secured with IARPD restoration. Moreover, maintenance problem that may occur in the future was minimized by providing an appropriate denture design and occlusal scheme through several provisional restorations. This case can be expected to have a favorable prognosis in the long term.

다수의 치아를 상실한 부분무치악 환자의 치료방법으로는 임플란트 고정성 보철물과 가철성 국소의치가 주로 이용되며, 최근에는 골흡수가 심한 부분무치악 환자에서 의치의 유지와 안정을 위해 임플란트를 추가적으로 이용하는 임플란트 보조 국소의치(implant-assisted removable partial denture, IARPD)를 전략적으로 선택하게 된다. 안면골 감염의 일종인 골수염으로 인한 악안면 구조의 상실은 저작, 연하, 발음과 같은 기능장애 및 사회적, 심리적인 영향을 유발하므로 상실된 조직회복을 위해 가철성 수복이 필요하고 지대치와 국소의치의 설계가 치료의 성공에 더욱 중요한 역할을 담당한다. 이 경우 전통적인 가철성 국소의치에 비해 높은 유지력과 안정성을 가지는 IARPD는 좋은 예후를 보일 수 있다. 본 증례는 골수염 치료로 인해 골결함이 있는 부분무치악 환자에서 IARPD 수복으로 의치의 안정성을 확보하고, 여러 차례에 걸친 임시수복을 통해 적절한 의치 설계와 교합양식을 부여함으로써 최종적으로 발생할 수 있는 문제점을 최소화하고 장기적으로 양호한 예후를 기대할 수 있기에 이를 보고하는 바이다.
