1. How many
applications are possible with a single Variolink® Veneer
syringe?
One syringe of Variolink Veneer will cement approximately
7 veneers. (top
of page)
(Each syringe contains 1.5 ml of material,
which corresponds to approximately 2.5 g of material (or 2,500 mg).
A single
veneer requires around 350 mg of cement. This means that a
single syringe is sufficient for
around 7 veneers.) (top

2. Can Variolink® Veneer
be mixed with a catalyst to ensure a dual-curing process?
No. Variolink Veneer has been designed as a purely light-curing
cement and does not include any self-curing
initiator components
(e.g. amines). The curing process cannot be
triggered by adding a catalyst paste.
(Shade stability is maintained
through the elimination of the self-curing amines.) (top

3. Which adhesives are recommended for
the cementation of Variolink® Veneer?
To achieve good long-term results, etching of the enamel with
37% phosphoric acid is recommended.
Based on the total-etch
technique, Variolink Veneer may then be bonded with the tried-and-tested
adhesives
Syntac® or Excite®.

4. What procedures should be observed when applying
the adhesive in order to ensure a precision fit?
When using Excite®, the
adhesive (on the tooth structure) is light-cured prior to cementation
with Variolink Veneer.
Due to the low film thickness of
Excite, no problems are to be expected regarding the accuracy
of fit. If Syntac®
is used, the protocol does not
include a separate light-curing step, as Heliobond has a much higher film thickness.
After
seating the
veneer, the Syntac bonding agent is cured through the veneer together with the
luting cement.

5. What are the main advantages of Variolink® Veneer
over Variolink® II ?
Some shades in the Variolink Veneer range (HV+1, MV0, LV-1) feature
a significantly higher level of translucency
than those of Variolink
II. In addition, the cement offers an improved consistency, less
stickiness and easier clean-up
due to the modified filler technology. (top

6. What are the main advantages
of Variolink® II
over Variolink® Veneer
?
All Variolink II shades feature a higher
level of radiopacity than the Variolink Veneer shades. Moreover,
Variolink II offers
a dual-curing mechanism, by incorporating the
catalyst pastes. Variolink
II is also available in two different consistencies.

7. Why do the try-in shades appear different than the
cement shades when dispensed on a mixing pad?
The try-in pastes and the cement are different chemistries. Due
to this, the try-in pastes will appear more intense or
have higher
chroma when dispensed in a bulk amount on a mixing pad. When the Try-in Paste is thinned out under
the restoration it will match the shade/effect of the final cured cement. (top

8. Were there any changes made
to the system? (Are the any differences between Appeal® and
Variolink® Veneer?)
Yes. We took the opportunity to incorporate suggestions
from the market to make the product even better at the time
of
re-branding Appeal to Variolink Veneer. The -3 shade and
the +3 shades are now more intense. The +3 shade is
now
brighter and more opaque (increased value). The -3 shade
is now higher in chroma – more color (lower value.)
The
try-in pastes for these two shades were also adjusted accordingly. These
were the only changes made to the
system beyond the labeling
(re-branding). (top

9. What cement do we recommend in place of Appeal® Posterior?
Appeal Posterior has been discontinued. Our
#1 recommended posterior cement is Multilink® Automix.
For
those dentists preferring to use a Total Etch bonding technique,
we would recommend Variolink® II (dual-cure)
for posterior
applications. For those dentists insisting on a microfill
chemistry for the posterior, Dual® Cement
is still
available for posterior applications. (top
