WHAT ARE THE PROPERTIES OF DENTIN?
The brightness value of the dentin is decisive for the final result of the restoration. In virtually
all the shade ranges, the dentin has to feature a high brightness value. The opaquer supports
the dentin, which is, however, not always sufficient.
Depending on the ceramic type and properties, the dental technician has to process the
Dentin material in different ways to achieve his goal. Based on this example, I like to show
how different ceramic systems can be.

Feldspar ceramics
Low colour saturation
High brightness value
IPS Classic – high translucency, low colour saturation, high brightness value
You have to focus on the dentin shade in particular. The ceramic has a very low colour saturation and may lose a lot of colour with multiple firing
cycles. This is particularly the case with high-fusing ceramic materials, such as feldspar and leucite. The colour and chroma have to be compensated
by Intensive Dentin or Deep Dentin materials.

Leucite metal-ceramics
High colour saturation
Mean brightness value
IPS InLine – high translucency, high colour saturation, mean brightness value
The brightness value has to be mastered, as high translucency and high colour saturation result in a low brightness value. This is easily achieved
using Deep Dentin materials.

The fluorapatite crystals have a very lifelike light scattering/light reflection. Hence, highly aesthetic results can be easily achieved.
