초록

최근 CAD-CAM (computer-aided design-computer-aided manufacturing) 방식의 보철물의 제작이 늘어남에 따라 CAD 소프트웨어 내 가상 교합기의 이용도 증가하고 있다. 가상 교합기에 상악을 위치시키는 다양한 방법 중에는 안궁을 이용하지 않고 CBCT (cone-beam computed tomography) 혹은 안면 스캔을 이용하는 방법이 존재한다. 본 증례에서는 다수의 치관 파절과 교합 평면의 부조화가 관찰된 환자에게 상악 총의치 및 하악 고정성 보철 수복을 통한 전악 구강 회복을 계획하였다. 복제한 상악 임시의치에 방사선 불투과성 마커를 부여하여 폐구 인상을 채득하고, 이를 스캔하여 CBCT 상에서 위치시켰다. CBCT 상에서 양측 하악 과두의 medial pole을 잇는 접번축과 Frankfort horizontal plane을 지정하고 이를 활용하여 가상 교합기 부착을 시행하였다. 상악 총의치 및 하악 고정성 보철물을 제작하였으며, 심미적이며 기능적으로 만족스러운 결과를 얻었기에 이를 보고하는 바이다.

With the increasing use of CAD-CAM (computer-aided design-computer-aided manufacturing) methods for prosthesis fabrication, utilization of virtual articulators in CAD software has also increased. Among the various methods of positioning the maxilla in a virtual articulator, there are techniques that utilize CBCT (cone-beam computed tomography) or facial scans without the use of a facebow. In this case, a full-mouth rehabilitation was planned for a patient who exhibited multiple crown fractures and occlusal plane disharmony through maxillary complete denture and mandibular fixed prosthetic restoration. Radiopaque markers were added to the duplicated maxillary temporary denture to take closed-mouth impression, which was then scanned and positioned on the CBCT. On CBCT, hinge axis connecting the medial poles of both mandibular condyles along with the Frankfort horizontal plane was designated and utilized to perform virtual articulator mounting. Maxillary complete denture and mandibular fixed prostheses were fabricated, resulting in satisfactory aesthetic and functional outcomes.
