Abstract

In this case, a CAD-CAM complete denture that can be easily remanufactured and reduced the number of visits was decided in consideration of the fact that it was difficult to visit the dental hospital and many existing dentures were lost because the patient was inpatient in a nursing hospital. In order to reflect the shape, vertical dimension, and maxillomandibular relationship of the existing provisional dentures adapted by the patient to the fabrication of the final denture, the existing provisional dentures were scanned and closed mouth impression was taken with the printed individual tray. After digital facebow transfer using UTS CAD and arranging artificial teeth in CAD software, the maxillary and mandibular complete dentures were fabricated by milling the denture base and artificial teeth at once with the monolithic disc.

본 증례는 요양병원에 입원치료 중인 환자에서 치과에 내원하기 힘든 점과 의치 분실이 많은 점을 고려하여 내원 횟수를 감소시키고 재제작이 쉬운 CAD-CAM 총의치를 제작하였다. 환자가 적응한 기존 임시의치의 형태 및 수직고경, 악간관계를 최종의치 제작에 반영하기 위해 기존 임시의치를 스캔하고 프린팅한 개인트레이로 폐구인상을 채득하였다. UTS CAD를 이용하여 디지털 안궁이전하고 CAD 소프트웨어에서 치아배열 후 상하악 총의치를 단일 구조의 디스크로 의치상과 인공치를 한번에 절삭하여 제작하였다.
