Abstract

Traditional options for posterior edentulous treatment include removable partial dentures and implant fixed prostheses. Recently, the concept of implant assisted removable partial denture, in which two treatments are fused, has been introduced in consideration of systemic health and patient's needs, costs, residual alveolar bone status and so on. Implant assisted removable partial denture has the advantage of increasing the retention and stability of the denture and improving its esthetics in cases of large bone defects or biomechanical disadvantages. In addition, it is possible to strategically place the implants in a site where the alveolar bone is relatively sufficient, thereby overcome the limit of the conventional removable partial denture design as well as reducing the burden on a wide range of implant surgery. Cost reduction is also expected. In this case, the patient was treated by placing the implant in both premolar sites of the mandible and fabricating the distal extension removable partial denture with the implant fixed prosthesis as an abutment. After delivering the definitive prosthesis, the patient showed satisfaction with the masticatory function and esthetics. and has been regularly followed-up for more than one year. The following 20-months follow-up case report describes the design of an implant-assisted-removable partial denture (IARPD) in which two cementretained implant crowns used to provide support and stability.

후방 무치악 부위를 수복하는데 있어서 선택할 수 있는 전통적인 치료방법으로는 가철성 국소의치와 임플란트 고정성 보철물이 있다. 최근, 환자의 전신 건강과 심미적 요구사항, 치료 비용, 잔존 치조골 상태 등을 고려하여, 두가지 치료가 결합된 임플란트 융합 국소의치(implant assisted RPD)개념이 이용되고 있다. 임플란트 융합 국소의치는 치조골 결손부가 큰 경우나, 생역학적으로 불리한 경우에 전통적인 가철성 국소의치보다 유지력과 안정성을 증진시킬 수 있으며 심미적이라는 장점이 있다. 또한 치조골 양이 상대적으로 많은 부위에 전략적으로 임플란트를 식립하여 전통적인 국소의치 디자인의 한계를 개선할 수 있을 뿐 아니라, 다수의 임플란트 식립을 통한 고정성 보철물에 비해 환자의 수술 부담을 줄여줄 수 있으며, 비용 절감 효과도 기대할 수 있다. 본 증례의 환자는 하악 양측 소구치부에 단일 임플란트를 식립하여, 임플란트 고정성 보철물을 지대치로 하는 양측성 후방연장 국소의치를 제작하여 치료를 진행하였다. 최종 보철물 장착 후 환자는 저작 기능 및 심미에 대해 만족도를 나타내었다. 이후 1년 이상 주기적인 관찰을 통해 예후를 관찰 중이다. 하악 부분 무치악 환자에서 임플란트를 이용한 가철성 국소의치 수복을 통해 증진된 지지와 안정을 얻었기에 이를 보고하는 바이다.
