摘要：
Disclosed are a patient-customized 3D bone cutting guide, and a manufacturing method, a recording medium, and a manufacturing apparatus thereof. According to one embodiment of the present invention, a bone cutting guide manufacturing method comprises: a) an image file generation step of generating a 3D skull image file of a patient； b) a symmetry determination step of using the 3D skull image file to determine whether the mandibular is symmetric based on the left and right central planes of the face and the mandibular； c) a mirroring step of mirroring a normal portion from the left and right sides of the skull based on to the left and right central planes of the face and the mandibular to overlap an image representing the normal portion with an image representing an abnormal portion based on data acquired through the symmetry determination step； d) a cut portion extraction step of extracting a bone portion to be cut from the abnormal portion through the mirroring step； e) a shape data extraction step of extracting shape data of a guide main body with a structure corresponding to a surface structure of the bone to be cut and drill hole shape data considering cut depth data of the bone to be removed based on the data acquired through the cut portion extraction step； and f) a bone cutting guide manufacturing step of manufacturing a bone cutting guide including the guide main body with a drill hole formed therein based on the data acquired through the shape data extraction step. Accordingly, a part of an abnormally hypertrophied bone can be correctly and stably cut, thereby securing precision and reliability of a bone cutting operation.COPYRIGHT KIPO 2020환자맞춤 3차원 골 삭제 가이드, 그 제작방법, 기록매체 및 그 제작장치가 제시된다. 본 발명의 실시예에 따른 골 삭제 가이드 제작방법은, a) 대상 환자의 두개골 3차원 이미지 파일을 생성하는 이미지파일 생성단계； b) 상기 두개골 3차원 이미지 파일을 이용하여 얼굴과 턱뼈의 좌우 중심평면을 기준으로 턱뼈의 대칭 여부를 판단하는 대칭성 판단 단계； c) 대칭성 판단 단계를 통해 획득한 데이터를 바탕으로, 두개골의 좌측과 우측 중 정상인 부분을 얼굴과 턱뼈의 좌우 중심평면을 바탕으로 미러링하여 정상 부분을 나타내는 이미지와 비정상 부분을 나타내는 이미지를 겹치도록 배
