IVOCLAR Vivadent IPS Empress Direct Shade Guide - Enamel

Translucency and opacity
Like natural dentin, the IPS Empress Direct Dentin shades exhibit higher opacity and more opacious saturated chroma than the Enamel materials. They support the basic color of the tooth structure from within. The translucency of the Enamel materials has been adjusted to diffuse the dentinal substrate. Further gradations in translucency are achieved with the Trans 20, Trans 30 and Opal shades.
The well-balanced and mutually complementing translucencies of the IPS Empress Direct Dentin and Enamel materials give you the power to create exceptional esthetics with accurate color every time
New opalescent shade
Opalescence is evident in the incisal area of natural teeth. In simple terms, this optical effect is based on the different ways in which long waves (red) and short waves (blue) of light are scattered. If a tooth is examined in incidental light it appears to have a bluish tinge, while in transmitted light this color changes to reddish-orange
This effect has to be imitated with the corresponding materials in the restoration of teeth
Quick and accurate shade match
Two autoclavable shade guides depict the various shades and translucency levels of the IPS Empress Direct system. As with the IPS Empress all-ceramic materials, the shade tabs are made of high quality ceramic to provide long term stability for consistent shade match over time
