Die shade selection
The shade of the prepared tooth may be
determined using the IPS Empress die
material shade guide. The shade of the
prepared tooth and the desired tooth shade
are critical for the selection of the ingot
shade. The correct brightness value of the
final shade is determined by the ingot
material. Masking of a dark preparation is
usually achieved by using an ingot that
exhibits both a high degree of opacity and a
lower colour intensity. The proper final
shade is a combination of the following:
✓
die shade
✓
ingot
✓
staining or layering procedure
✓
cementation material
