In clinic, esthetic restoration of a defective natural tooth with composite resin is challenging procedure and needs complete understanding of the color of tooth itself and materials used. The optical characteristics of the composites are different because the chemical compositions and microstructur...

가시광선의 파장 범위는? | 사람은 외부에서 들어오는 물체의 빛을 눈의 망막을 통해 받아들여 원추 혹은 간상세포의 시세포를 통해 색을 지각하고 이를 대뇌에서 인지하여 색을 구별하게 된다. 이때 사람의 눈으로 느낄 수 있는 빛은 그 파장이 약 400 nm에서 700 nm 사이에 위치하는데 이를 가시광선이라 한다. 색은 사람마다 느끼는 주관적인 감각이 개입되므로 이를 표준화하기 위하여 표색계(color system)을 고안하게 되었다. | |
치과 임상에서 일반적으로 사용되는 레진의 색을 고르는 기준은? | 임상에서 복합 레진 수복을 하는 경우 자연치와 색이 잘 맞지 않는 경우가 종종 있다. 치과 임상에서 가장 일반적으로 사용되는 색의 기준은 Vita shade guide일 것이다. 대부분 이를 기준으로 레진의 색을 고르고, 기공소에 기공물 제작을 의뢰하고, 재료를 구입하며 기록을 할 것이다. | |
