Abstract

For fully edentulous patients, implant-supported overdenture can be considered to enhance chewing efficiency and denture stability. Implant planning software can be used to fabricate a surgical guide for a more precise consideration of anatomic factors and prediction of the shape of definitive prosthesis. Though there are many possible attachments for implant overdenture, milled bar can be useful due to its splinting effect of implants and rigid support of overdenture. This report presents a case of implant-supported milled bar overdenture after guided implant surgery performed with two surgical guide that was fabricated before and after bone reduction.

완전 무치악 환자에게서 잔존 치조골의 흡수가 심할 경우 의치의 저작효율과 안정성 향상을 위해 임플란트로부터 지지를 얻는 피개의치를 고려해볼 수 있다. 임플란트 식립 위치를 선정할 때 디지털 진단 프로그램을 이용하면 환자의 해부학적 요소와 최종보철물의 형태를 고려한 수술용 가이드를 만들어 임플란트 수술의 정확도를 높일 수 있다. 임플란트 지지 피개의치에서 다양한 부착장치 중 milled bar 경우 임플란트간의 연결고정 효과뿐만 아니라 견고한 지지를 얻을 수 있는 이점이 있다. 이에 본 증례에서는 치조골 삭제 전, 후의 상황을 가정한 두 개의 수술용 가이드를 이용하여 임플란트를 식립한 후 milled bar를 이용한 임플란트 피개의치를 장착해주어 기능적이고 심미적인 결과를 얻었다.
