3.1 Shade selection
1. Prior to shade selection, clean the tooth surface with prophylaxis paste to remove plaque or
surface stain.
2. Select the shade while teeth are hydrated.
Ceram.x Spectra™ ST restorative has been scientifically designed to allow the tooth structure
enamel and dentin to blend together with the composite with a life-like translucent result. The
5 A shades of Ceram.x Spectra™ ST restorative adequately reproduce the traditional 16 VITA
®
shades.
For esthetically demanding cases requiring special effects to achieve the desired esthetic result,
Ceram.x Spectra™ ST Effects offers 2 dentin shades and 1 enamel shade that work with the
Ceram.x Spectra™ ST universal CLOUD shades in a simplified layering system to provide added
opacity and/or translucency as needed.
For shade selection, there are two tools that may be used:
• The Ceram.x Spectra™ ST and Ceram.x Spectra™ ST Effects shade guide. The Ceram.x
Spectra™ ST and Ceram.x Spectra™ ST Effects shade guide consists of tabs, which are man-
ufactured from composite with optical properties close to those of Ceram.x Spectra™ ST and
Ceram.x Spectra™ ST Effects.
• The VITA
®
classical shade guide in combination with the i-shade label. The Ceram.x Spectra™ ST
and Ceram.x Spectra™ ST Effects i-shade label facilitates shade selection by assigning one of the
five universal CLOUD shades to each of the 16 VITA
®
shades.
3.1.1 Shade selection with the Ceram.x Spectra™ ST and Ceram.x Spectra™ ST Effects shade
guide
1. Use the shade tabs of the Ceram.x Spectra™ ST and Ceram.x Spectra™ ST Effects shade guide
to select the shade closest to the shade of the area to be restored.
Avoid contamination of the shade guide.
To prevent the shade guide from exposure to spatter or spray of body fluids or con-
taminated hands it is mandatory that the shade guide is handled offside the dental
unit with clean/disinfected gloves. For shade selection, remove individual tabs from
shade guide holder.
