Abstract

With development of digital dentistry, the 3-dimensional (3D) manufacturing industry using computer-aided design and computer-aided manufacturing (CAD/CAM) has grown dramatically in recent years. Denture fabrication using digital method is also increasing due to the recent development of digital technology in dentistry. The 3D manufacturing process can be categorized into 2 types: subtractive manufacturing (SM) and additive manufacturing (AM). SM, such as milling is based on cutting away from a solid block of materal. AM, such as 3D printing, is based on adding the material layer by layer. AM enables the fabrication of complex structures that are difficult to mill. In this case, additive manufacturing method was applied to the fabrication of the resin-based complete denture to a 80 year-old patient. During the follow-up periods, the denture using digital method has provided satisfactory results esthetically and functionally.

디지털치의학의 발달과 함께 computer-aided design and computer-aided manufacturing (CAD/CAM)을 이용한 3D 제작산업이 최근 급격한 성장을 하고 있다. 디지털 방식을 이용한 의치 제작 또한 최근의 디지털치의학 기술의 발전으로 증가하는 추세에 있다. CAD/CAM 제작방법은 크게 두가지 타입으로 나눌 수 있다: 절삭가공, 적층가공, 밀링과 같은 절삭가공은 블록 형태의 재료를 깎아 제조하는 기술을 토대로 하며, 3D printing과 같은 적층가공은 재료를 적층 방식으로 쌓아 올려 제조하는 기술을 토대로 한다. 적층가공은 밀링이 어려운 복잡한 구조의 제작에 적용할 수 있다. 본 증례에서, 적층가공방법이 레진상 총의치 제작에 이용되었다. 디지털방식을 적용한 의치의 사용기간동안 기능적, 심미적으로 만족할 만한 결과를 보여주었다.
