Abstract

두개골 성형술에 사용되는 3차원 임플란트 및 이의 제작방법에서, 상기 3차원 임플란트는 환자의 두개골에 대한 컴퓨터단층촬영(CT) 정보를 바탕으로 생성된 두개골에서의 결손 부위에 대한 이미지를 바탕으로 제작된다. 이 경우, 상기 3차원 임플란트는, 상기 두개골의 결손 부위와 동일한 형상을 가지는 몸체부, 상기 몸체부의 전단에 위치하여 환자의 관전두골(zygomaticofrontal suture)에 고정되는 부분으로, 상기 몸체부보다 큰 두께를 가지는 확장부, 및 상기 몸체부의 외곽선을 따라 돌출되어, 상기 두개골과 고정되는 고정부를 포함한다.
