Abstract

Generally dentures are manufactured by conventional method, however the frequency of fabricating denture using digital method is increasing due to the recent development of digital technology in dentistry. The digital method of manufacturing denture is classified into two systems; 3D scan of the impression to arrange the artificial teeth on the CAD (Computer-aided design) and 3D printing to produce the resin-based complete denture, or 3D scan of the model to design of the framework using CAD, resin pattern formation by 3D printing and casting of metal framework of complete denture or removable partial denture. In this case report, electronic surveying and design the metal framework of the dentures were performed using CAD program, and plastic resin patterns fabricated by 3D printing were casted for upper full denture and lower removable partial denture. During follow-up periods, dentures using digital method have provided satisfactory results esthetically and functionally.

현재까지 의치는 전통적인 방법을 이용하여 제작하는 것이 일반적이지만, 최근 디지털 기술의 발달로 이를 이용한 의치 제작 빈도가 증가하는 추세이다. 디지털 방식을 이용하여 의치를 제작하는 방법에는 인상체를 3D 스캔하여 CAD 상에서 인공치를 배열한 뒤 이를 3D 프린팅하여 레진상 총의치를 제작하는 방식과 모델을 3D 스캔 후 CAD를 이용하여 frame-work을 디자인하고 3D 프린팅으로 resin pattern을 제작하여 이를 주조 후 금속상 총의치나 국소의치를 제작하는 방식이 대표적이다. 본 증례에서는 디지털 방식의 의치 제작 방법으로써 전자 서베잉을 이용한 진단과 CAD 프로그램을 이용한 framework 디자인, 그리고 이를 3D 프린팅 후 주조하여 상악 총의치와 하악 국소의치를 제작하였으며, 만족스러운 결과를 얻었기에 이를 보고하고자 한다.
