CBCT를 기반으로 안궁이전을 시행한 상악 총의치 및 하악 고정 성 보철 수복 증례

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. [ABSTRACT FROM AUTHOR]
