초록
상악 완전 무치악에 6개 이상의 임플란트가 식립된 경우 임플란트-지지형 피개의치 제작이 가능하다. 임플란트-지지 피개의치에 사용되는 다양한 부착장치 중에 milled-bar의 경우 의치의 회전을 허용하지 않고, 안정성이 뛰어나며, 여러 개의 임플란트를 연결 고정하는 효과를 가진다는 장점이 있다. 본 증례에서는 전치부에 심한 골소실을 동반한 상악 완전 무치악 환자에서 세 가지 다른 시스템으로 구성된 7개의 임플란트 상부에 CAD/CAM 맞춤형 지대주와 시멘트 접착형의 milled bar를 이용한 피개의치를 제작하여 상실된 심미와 기능을 효과적으로 회복하였다.
Abstract
In patients with fully edentulous maxilla, fabrication of implant-supported overdenture can be a viable treatment option, when a minimum of six implants were strategically placed. Among several attachment systems used for implant-supported overdentures, milled-bars prevent rotational movement of denture, thus showing great stability, and have the advantage of splinting multiple implants with each other. In this case report, a milled-bar supported overdenture was fabricated for a patient suffering from condition of fully edentulous maxilla with severe ridge resorption in the anterior residual ridge. Seven implants composed of three different systems were effectively utilized by CAD/CAM customized abutment and cement-retained milled bar.
