CAD/CAM 시스템을 이용한 의치 제작은 환자의 내원 횟수를 감소시키고 기공과정에서 발생하는 오차를 감소시키는 장점이 있다. 본 환자는 상악 잔존치 발거에 따라 완전무치악 상태가 된 환자로, 하악 잔존치조제의 흡수로 기존 하악 총 의치의 유지와 안정이 부족하여 하악 임플란트 유지 피개의치 및 상악 총의치 수복을 계획하였다. 폐구상태에서 환자의 기능운동을 이용해 인상채득하는 BPS (Biofunctional prosthetic system)개념을 디지털화하여 Gnathometer CAD로 수직교합고경을 설정하고 고딕아치로 중심위를 인기하였으며 UTS CAD로 디지털 안궁이전하였다. CAD/CAM 시스템과 monolithic disc를 이용하여 제작한 상악 총의치, 하악 임플란트 유지 피개의치의 유지, 안정, 지지가 양호하며 환자는 향상된 의치 기능과 심미성에 만족하였기에 보고하는 바이다.

Fabrication of dentures using CAD/CAM system has the advantage of reducing the number of patient visits and reducing errors during laboratory work. After the extraction of maxillary residual teeth, this patient changed to a completely edentulous state and the stability and retention of the existing mandibular complete denture were insufficient due to the absorption of the mandibular residual ridge, so the restoration of the mandibular implant retained overdenture and maxillary complete denture were planned. By digitizing the concept of BPS (Biofunctional prosthetic system) that uses the patient's functional movement in closed mouth technique, the vertical dimension was taken by Gnathometer CAD and digital facebow transfer was performed using UTS CAD. In this case, fabrication of maxillary complete denture and mandibular implant-retained overdenture using monolithic disc and CAD/CAM system demonstrated favorable denture retention, stability, and support and the patient is satisfied with improved functions and esthetic of dentures.
