목적 : 이 연구의 목적은 네비게이션 가이드 시스템(navigation guide system)을 이용한 치조정 접근 상악동 거상술(crestal approach sinus augmentation)을 제안하고 이러한 새로운 술식을 사용한 증례를 보고하고자 함이다. 연구 방법 : 상악동 거상술이 요구되는 임플란트 환자중 잔존골 4mm이상이며 치조정접근 상악동거상술이 필요한 환자 5명을 선정하였다. 이 환자들의 구강내 인상채득과 CBCT촬영을 하여 디지털 치료계획을 시행하였다. 이때 치조정 접근을 위한 디지털 치료계획도 시행하였으며 이를 이용하여 각 환자당 치조정접근 상악동 거상술용 가이드와 임플란트 식립용 가이드 총 2개의 가이드를 제작하였다. 결과 : 총 5명의 환자에서 치조정 접근 상악동 거상술 가이드를 이용하여 별다른 문제없이 안정적으로 8개의 임플란트를 식립하였다. 결론 : 네비게이션 가이드 시스템를 사용한 치조정 접근 상악동 거상술은 술전 디지털 치료계획을 통해 잔존골이 부족한 상악에서 안전하고 정확한 임플란트 식립을 가능하게 할 것이라 사료된다.
