Contraindication
The application of Variolink Esthetic is contraindicated
– if a dry working field cannot be established or the stipulated working
procedures cannot be applied;
– if a patient is known to be allergic to any of the ingredients of Variolink
Esthetic.
Side effects
Systemic side effects are not known to date. In individual cases, allergic
reactions to individual components have been reported.
Interactions
Phenolic substances (e.g. eugenol, wintergreen oil) inhibit polymerization.
Consequently, the application of products containing these components, e.g.
mouth rinses and temporary cements, must be avoided.
Disinfectants with an oxidative effect (e.g. hydrogen peroxide) may interact
with the initiator system, which in turn may impair the curing process.
Therefore, do not disinfect the preparation and the syringe using oxidative
agents. Disinfection may be carried out, for instance, by wiping with medical
alcohol.
Alkaline jet mediums applied on dentin (e.g. Airflow) may compromise the
effect of self-etching adhesives.
Application
For more detailed information also refer to the Instructions for Use of the
products used in conjunction with Variolink Esthetic.

Removal of temporary restoration and cleaning of the cavity
Remove possible residue of the temporary luting composite from the
cavity or the preparation with a polishing brush and an oil- and fluoride-
free cleaning paste (e.g. Proxyt® fluoride-free prophy paste). Rinse with
water spray.
Subsequently, dry with oil- and moisture-free air. Avoid overdrying.
Note:
Cleaning with alcohol can lead to dehydration of dentin.
2 Try-in of the restoration and isolation
Seat the restoration using the desired Variolink Esthetic try-in paste and
check the shade, fit and occlusion of the restoration.
Care should be taken when checking the occlusion of fragile and brittle
ceramic objects before they are permanently cemented, as there is a risk
of fracture.
If necessary, make adjustments with fine diamonds at medium speed
and with slight pressure and adequate water cooling. Polish ground
surfaces.
When an adhesive luting protocol with composites is used, safe isolation
of the operating field – preferably with a rubber dam, e.g. OptraDam®
Plus, or alternatively with cotton rolls and a saliva ejector – is required.
If the dental hard tissue is contaminated with saliva or blood during
try-in, it needs to be cleaned again as described in section 1.
3 Pre-treatment of the restoration
3.1 If a restoration which has been pre-treated in the dental laboratory
is contaminated with saliva or blood during try-in, the contaminated
bonding surface of the restoration needs to be cleaned as follows:
– Following try-in, thoroughly rinse the restoration with water spray
and dry with oil-free air.
– Shake Ivoclean before use and completely coat the bonding surface of
the restoration with the product using a microbrush or bush.
– Leave Ivoclean to react for 20 s, then thoroughly rinse with water
spray and dry with oil-free air.
– Subsequently, prime the bonding surfaces with a bonding agent that
is appropriate for the respective restorative material (e.g. Monobond®
Plus). Make sure to observe the Instructions for Use of the bonding
agent applied.
3.2 Restorations that have not been pre-treated by the dental laboratory
should be rinsed with water spray and dried after the try-in procedure.
3.2.1 Subsequently, condition the bonding surfaces of the restoration as
follows:
a) Glass-ceramic restorations (e.g. IPS Empress®)
– Etch with 5% hydrofluoric acid (e.g. IPS ® Ceramic etching gel) for
60 s or according to the instructions of the manufacturer of the
restorative material.
– Thoroughly rinse with water spray and dry with oil-free air.
b) Lithium disilicate glass-ceramic restorations (e.g. IPS e.max Press,
IPS e.max CAD)
– Etch with 5% hydrofluoric acid (e.g. IPS Ceramic etching gel) for
20 s or according to the instructions of the manufacturer of the
restorative material.
– Thoroughly rinse with water spray and dry with oil-free air.
c) Composite or fibre-reinforced composite restorations
– Blast the internal surface of the restoration (according to the
instructions of the manufacturer of the restorative material).
– If necessary, clean the restoration in an ultrasonic unit for about
one minute.
– Thoroughly rinse with water spray and dry with oil-free air.
3.2.2 Apply Monobond Plus with a brush or a microbrush to the pre-treated
surfaces, let it react for 60 s and then disperse it with a strong stream of air.
4 Pre-treatment of the preparation and application of the adhesive
(e.g. Adhese® Universal)
Please observe the Instructions for Use of the adhesive used.
