5.2 Shade system
G-ænial offers flexibility, enabling placement of aesthetically invisible single-shade restorations or
aesthetic masterpieces with a multi-shade build-up. in order to achieve this, 3 clearly differentiated
shade groups have been defined for G-ænial:
• Standard shades: for the single-shade restorations
• Outside shades: placed on top of Standard shades in aesthetically demanding cases
• Inside shades: placed underneath Standard shades in aesthetically demanding cases
Standard shades
Standard shades have been designed to be used mainly in the single-shade technique and present
a very delicate balance between value, translucency, hue and chroma. they are grouped into a
(reddish-brown), B (reddish-yellow), c (grey), Bleach and cervical shades. each shade from the
same group has the same hue and conforms to the arrangement of the Vita® classical shade guide,
with an increasing amount of chroma per group.

as can be seen on Figure 13, G-ænial shade a3
applied to the central part of single Vita shade
guide tabs has unique blending and invisible
properties: the material adapts to the underneath
shade tabs and perfectly matches the environment.
as a result, one shade will be sufficient for most
cavities.
