3.1 Direct Restoration
Such as: Cavity restoration, veneering, cosmetic and functional re-
shaping, core build-up, splinting, amalgam, composite, ceramic and
porcelain repairs.
3.1.1 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.
TPH 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
TPH Spectra ST restorative adequately reproduce the traditional 16
®
VITA shades.
®
For shade selection, there are two tools that may be used:
• The VITA classical shade guide in combination with the i-shade
®
label. The TPH Spectra ST i-shade label facilitates shade selec-
®
tion by assigning one of five TPH Spectra
the 16 VITA shades.
®
• The TPH Spectra ST shade guide. The TPH Spectra
®
guide consists of tabs, which are manufactured from composite
with optical properties close to those of TPH Spectra
