Inside and Outside Special shades
although excellent aesthetics can be achieved for the majority of cases with just a single shade,
there may be times when a multi-shade technique is preferred, such as when extensive restorations
are required. G-ænial offers two additional types of shades to choose from, called Special Shades.
inside shades are placed underneath a Standard Shade, and are more opaque to block the
transmission of light from the oral cavity. Outside shades are placed on top of Standard shades to
copy the value (lightness/darkness) of a tooth, to mimic age-dependent changes in the enamel and
to give more “depth” to a final restoration.
Outside Special Shades – replacing ename
Outside special shades give an extra dimension to the restoration. monochromatic composite
restorations are often found to have the appearance of less vitality compared to ceramic. this
happens when the value of the restoration is not appropriate for the tooth; the enamel surface is
the main contributor to the value of a tooth.
enamel changes over time, becoming thinner and more translucent. it also decreases in value from
high (whiter) to low (darker). Outside special shades are designed to reflect these changes, helping
the dentist to create restorations with age-appropriate values. Depending on the intended use,
several slightly-pigmented outside shades can be used to obtain a highly indication-specific hue
and chroma. Due to the uniqueness of these shades, a classification to Vita is not possible. For
shade reference, the G-ænial shade guide should be used.
Outside Shades offer the same degree of translucency, but have different values to provide for
age-appropriate values.

to mimic this change at, for instance, the incisal edges of teeth, ie (incisal enamel) and te
(translucent enamel) have been developed.
