Ivoclar Vivadent Dual Cement - Manual (Page 2)

Side effects
Systemic side effects are not known to date. In
indi-vidual cases, allergic reactions were reported.
Irritation of the pulp may occur without the use of a
suitable pulp/dentin protection or without base/liner
in deep or medium-sized cavities.
Interactions
Phenolic substances (e.g. eugenol) inhibit the poly-
merization. Therefore, materials containing such
substances should not be used in conjunction with
Dual Cement.
Application
Step-by-step
For detailed information, please also refer to the
Instructions for Use of the products mentioned.
1. Removing the temporary
Remove any residue of the temporary cement
from the cavity or the preparation using a
polishing brush and a cleaning paste that is
free of oil and fluoride. Subsequently, rinse with
water spray.
Note: Use only temporary cements that are
free of eugenol (e.g. Provilink
® ), since eugenol
may inhibit the polymerization of Dual Cement.
If Fermit
® /Fermit ® N is used for inlays, a
temporary cement is usually not required.
2. Trying-in the restoration
Check exact fit and proximal contacts of the
restoration. The occlusion should only be
checked after cementation (risk of fracture).
3. Isolating
The use of a rubber dam is recommended.
4. Conditioning of the restoration
According to the instructions of the
manufacturer.
5. Conditioning of the cavity/preparation
5.1 Etch the enamel margins, e.g. with Total Etch ,
for 30–60 seconds, rinse, and dry with water-
and oil-free air. If necessary, etch dentin
according to the instructions of the
manufacturer of the dentin adhesive used.
5.2 Apply a suitable dentin bonding agent (e.g.
Syntac ® , Excite ® – observe the corresponding
instructions for Use).
6. Mix Dual Cement in a 1:1 ratio. Dual Cement
must not be exposed to direct sunlight or other
intensive light sources during this process. The
working time of Dual Cement is 4–5 minutes
(at 23 °C / 73 °F).
6.1 Cool storage (2–8 °C / 36–46 °F) prolongs the
working time of Dual Cement.
6.2 Excessive mixing may result in air being trapped
in the material, which may hamper the poly -
merization of the material and subsequently
weaken the mechanical properties.
7. Apply Dual Cement on the restoration and in
the cavity (avoid entrapment of air).
8. Place the restoration, e.g. inlay.
9. Remove excess cement. The inlay can be
'secured' by removing occlusal excess and
quickly curing only the marginal areas by
means of a polymerization light. After that,
remove the remaining excess.
