초록

하악 완전 무치악 환자의 보철수복에 있어 임플란트 식립 후 피개의치 제작은 첫 번째 치료 옵션으로 고려된다. 코너스 타입 부착장치를 이용한 피개의치는 견고한 지지를 제공하고 cross arch stabilization을 이루도록 하여 교합압을 균일하게 분산시키며, 의치에 의한 이차 고정으로 장기간의 안정성을 제공한다. 최근 소개된 팔라듐-은(Pd-Ag) 합금(Innovium)은 팔라듐, 은, 금 등의 귀금속 함량이 72% 이상인 CAD-CAM 시스템 전용 귀금속 합금으로 코너스 타입 부착장치를 제작하는데 적합한 물성을 가지고 있다. 본 증례에서는 완전 무치악 환자에서 상악에는 통상적인 총의치, 하악에는 임플란트를 4개 식립한 후에 코너스 타입 부착장치 피개의치 수복을 하였다. CAD-CAM 시스템을 이용하여 팔라듐-은 합금(Innovium)으로 제작된 코너스 타입 부착장치를 장착하였으며 이를 통해 의치의 유지와 안정을 향상시켰으며 만족할 만한 결과를 얻었기에 보고하고자 한다.

In edentulous mandible, implant supported overdenture was considered as a first treatment option. Konus type attachment supplies rigid support and cross arch stabilization so that more favorable force transmission and distribution can be attained. In the dentistry, computer aided design-computer aided manufacturing (CAD-CAM) system makes it possible to fabricate restorations with high precision and effectiveness. Recently, Palladium-silver (Pd-Ag) alloy which is millable has been developed. This article presents that application of CAD-CAM Konus type attachment can be provide satisfactory stability and function on four-implant supported mandibular overdenture.
