3. GC GRADIA CHARACTERISTICS
1) GC GRADIA colour tones and translucency similar to those of natural teeth
Its level of brightness and light transmission is similar or closer to porcelain than conventional
composites. Where required, the underlying tooth preparation can be masked while maintaining
a natural, life-like appearing anterior jacket crown. Thus the GC GRADIA’s build-up technique
mirrows those used for ceramics.
2) Reduction of pale opalescence typical for composites
The opalescence and fluorescence features typical for composites could not be avoided so
far, especially with translucent colours. When a crown was seated under the light conditions
found in the mouth, the excessively opalescent colour would make it impossible to reproduce
the natural colour. These features have been changed in GC GRADIA by optimizing the filler
particle size, thereby controlling and adjusting the diffusion of light through the material. This
allows to maintain the desired colour, created at dentin level, also when the restoration is seated
in the mouth.
3) GC GRADIA’s complete spectrum of colours
GC GRADIA has a complete spectrum of colours comparable to natural dentition offering wider
range than other composite systems.
1. OPAQUS DENTIN (OD) is used to express the deep cervical colours. SHOULDER DENTIN (SD)
follows the same concept as shoulder ceramic bodies.
2. MAMELON STAIN (MS) allows to easily reproduce the dentin structure in the mamelon area.
INTENSIVE COLOR (IC) is available in 15 shades and is effective in characterizing crowns with
cracks, decalcification areas, etc.
3. ENAMEL INTENSIVE (EI) shades create the appearance of depth. CERVICAL TRANSLUCENT
(CT) has a translucent amber color that is particularly suitable for the cervical area.
4. HALO ENAMEL (HE) is used to clearly express the contour of the tooth. PEARL ENAMEL (PE)
is applied to express white lines/zones and cusp tips.
GC GRADIA’s wide range of colours enables restorations to appear more like porcelain than
other composites.

Comparison of fluorescence
A comparison of GC GRADIA’s translucent colour tones with its competitors demonstrates that colours and translucency are
similar. However, a comparison of fluorescence on a black background – as in the mouth – shows that GC GRADIA features a
more natural fluorescence compared with other products.
