Optional Flowable Liner: Placement of a compatible flowable liner
(available separately) prior to placement of TPH Spectra
tive is optional. Follow manufacturer's directions for use.
3.1.5.1 Applying TPH Spectra ST restorative
®
1. Dispense TPH Spectra ST restorative directly into the cavity prep-
®
aration/tooth surface from the Compules
pressure. Excessive force is not necessary. Alternatively, material
may be expressed onto a clean pad from the Compules
syringe and carried to the preparation with suitable placement in-
strument.
2. Adapt, contour and shape with appropriate composite instruments.
Material may be placed and light cured in increments up to 2 mm
[3.1.6 Light curing].
Technique Tip: For esthetic blending of shades, shade layers may be
individually cured to form a foundation for subsequent shade place-
ment.
TPH Spectra ST restorative resists slumping, allowing carving of the
®
majority of anatomical form prior to visible light curing.

materials containing camphorquinone (CQ) initiator, i.e. peak spectral
output 440-480 nm. Cure each increment for 10 seconds when using
a curing light that has a minimum irradiance of 800 mW/cm
Cure composite for 20 seconds when minimum irradiance is between
500 mW/cm² and 800 mW/cm².
Refer to curing light manufacturer's Instructions for Use for compat-
