소수의 임플란트를 전략적인 위치에 식립하여 제작한 임플란트 보조 국소의치를 이용하여 보다 유지력이 좋고 안정적인 국소의치를 제작할 수 있다. 특히 2 개의 임플란트에 대한 보험급여가 가능해지면서 소수의 임플란트를 매식해 국소의치를 위한 지대치로 이용하는 증례는 점차 증가되고 있으며 환자의 저작 기능 향상과 만족도 증진에 일조하고 있다. 본 증례는 편측에 2 개의 전치만 남은 부분 무치악 환자로 상악의 케네디 분류 I 급 국소의치로 수복한 결과 하악 전치부의 마모와 교합수직고경의 감소로 잦은 인공치와 국소의치의 파절이 나타났다. 최소한의 임플란트 지지 고정성보철물을 지대치로 사용하는 임플란트 보조 국소의치를 제작하여 기능적으로 만족할만한 결과를 얻었기에 이를 보고하고자 한다.
Implant-assisted removable partial dentures (IARPD) provide additional retention and stability by placing a small number of implants in the strategic positions. Since the two implants can be covered by National Health Insurance Services, the treatment modality using IARPD has been increased to restore partially edentulous patients with a few unilateral remaining teeth and improved the clinical effectiveness and patient satisfaction. The patient with two anterior unilateral remaining teeth showed a problem of frequent fracture of artificial teeth and denture base with maxillary Kennedy Class I RPD due to wear of mandibular anterior teeth and loss of occlusal vertical dimension. This case report suggested that the incorporation of a limited number of implants into IARPD could improve the function and patient satisfaction for the partially edentulous patients.
