restoratives
1. Dispense the composite material directly into the cavity prepara-
tion/tooth surface from the Compules
sure. Excessive force is not necessary. Alternatively, material may
be expressed onto a clean pad from the Compules
and carried to the preparation with suitable placement instrument.
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 Tips:
• Use a single opacity for most common cases: Because the
TPH Spectra ST universal CLOUD shades are designed to re-
®
place both dentin and enamel, a single universal CLOUD shade
is sufficient for most restorations. If esthetic blending of more than
one universal CLOUD shade is desired, shade layers may be in-
dividually cured to form a foundation for subsequent shade place-
ment.
• Use multiple opacities for esthetically demanding cases: For es-
thetically demanding cases such as a large Class IV or a through-
and-through Class III, TPH Spectra
shades can be used with TPH Spectra
shades in a simplified layering system to provide added opacity
and/or translucency.
– Restore the palatal half of the tooth with the dentin shade
Leave room for the universal CLOUD shade at the incisal edge.

– Place the universal CLOUD shade along the incisal edge and

– Restore the facial half of the tooth with the universal CLOUD

3.1.6 Light curing
1. Light cure each increment with a suitable curing light designed to
cure materials containing camphorquinone (CQ) initiator, i.e. peak
spectral output 440-480 nm. Cure universal A shades, BW, and
E1 increments for 10 seconds, and D1 and D3 shades for 30 sec-
onds when using a curing light that has a minimum irradiance of
800 mW/cm .
2
Cure universal A shades and BW for 20 seconds, E1 for 10 sec-
onds, and D1 and D3 shades for 40 seconds when minimum irradi-
ance is between 550 mW/cm² and 800 mW/cm².
Refer to curing light manufacturer's Directions for Use for compat-
ibility and curing recommendations.
Light curing of individual increments required when layer thickness reaches
2
2 mm.
