초록
다수 치아가 상실된 부분 무치악 환자의 전통적인 치료 방법으로 임플란트 고정성 보철물과 가철성 국소의치가 널리 이용되고 있다. 최근에는 소수의 임플란트를 보조적으로 이용하여 부가적으로 유지와 지지를 얻는 임플란트 융합 국소의치(Implant-assisted removable partial denture, IARPD)에 대한 관심이 증가하고 있다. 임플란트 융합 국소의치는 전통적인 가철성 국소의치에 비해 높은 유지력과 안정성을 가지며 심미적이다. 또한 소수의 임플란트 식립을 통해 환자에게 수술에 대한 부담을 줄여주며, 비용 절감 효과를 가진다. 본 증례의 환자는 상악에서 다수 치아를 상실한 부분 무치악 환자로 초기에 임플란트 고정성 보철물로 치료 계획하였으나 여러 요인에 의해 milled bar와 Locator attachment를 이용한 임플란트 융합 국소의치로 치료계획을 변경하였다. 이를 통해 기능과 심미에서 만족할 만한 결과를 얻었기에 보고하는 바이다.
Abstract
Implant-fixed prostheses and removable partial dentures are widely used as a traditional treatment method for partially edentulous patients who have lost multiple teeth. Recently, there has been increasing interest in implant-assisted removable partial denture (IARPD), which additionally obtains retention and support using a small number of implants. The IARPDs have higher retention, stability, and aesthetics than conventional removable dentures. It also has the effect of reducing the cost as well as the burden of surgery by placing a small number of implants at the edentulous site. In this case, the patient with a partial edentulous state that has multiple numbers of tooth loss in maxilla initially planned to be treated with implant fixed prosthesis. However, the treatment plan was changed to IARPD using Bar and Locator due to several factors. The clinical results were satisfactory on the aspect of esthetic and masticatory function.
