Abstract

Conventional removable partial dentures (RPDs) with distal extensions are associated with some problems, including lack of stability that calls for frequent relining, and cantilever actions of claps that can produce excessive loading to abutment teeth, and the need for unesthetic retentive arm clasps. Therefore, IARPDs (Implant-assisted RPD) that use implants to support or retain RPDs has been reported to improve stability, esthetics and masticatory performance of RPDs. Also, an IARPD that has zirconia occlusal table can prevent the incongruity of occlusal plane and the extrusion of antagonistic tooth. In this case of partially edentulous patient with crossed occlusion, each edentulous area was restored with implant fixed prosthesis and implant retained partial denture to suit each situation. Through the procedure, satisfactory outcomes were achieved both in functional and esthetic aspects.

기존의 후방 연장 국소의치는 재이장을 위한 잦은 내원의 필요성, 클래스프에 의한 지대치로의 과도한 응력, 클래스프의 노출에 의한 비심미성 등의 단점이 있다. 이에 임플란트를 이용하여 부가적인 지지나 유지를 얻는 Implant-assisted RPD(IARPD)는 국소의치의 안정성과 심미성, 그리고 저작 효율 증진에 도움을 줄 수 있다. 또한 의치의 교합면을 지르코니아로 교체한다면 인공치 마모로 인한 대합치의 정출 및 교합평면의 부조화를 예방할 수 있을 것이다. 본 증례는 엇갈린 교합을 가진 상하악 부분 무치악 환자에서 임플란트 고정성 보철물과 임플란트 유지 국소의치를 제작하여 전악 재건 시행한 증례로 주기적인 내원을 통해 기능적, 심미적으로 만족할만한 결과를 얻었기에 보고하고자 한다.
