Variolink Esthetic DC System Kit

Variolink Esthetic is a light- and dual-curing luting composite for the esthetic and permanent cementation of ceramic and composite resin restorations. This material represents the next generation of the well-established, esthetic cements Variolink II and Variolink Veneer.

Indications:

Variolink Esthetic DC

• Permanent cementation of glass-ceramic, lithium disilicate glassceramic and composite restorations (inlays, onlays, partial crowns, crowns, bridges)

Shades:

• Light+, Light, Neutral, Warm, Warm+

• 1 automix syringe Variolink Esthetic DC, 5g neutral
• 1 automix syringe Variolink Esthetic DC, 5g warm
• 1 syringe Variolink Esthetic Try-In-Paste, 1.7g light
• 1 syringe Variolink Esthetic Try-In-Paste, 1.7g neutral

• 1 syringe Liquid Strip, 2.5 g
• Various accessories

Shades

Variolink Esthetic is available in the following five shade gradations:

Shade         Effect

The gradation of Variolink Esthetic shades is based on the effect that a luting composite exerts on the brightness value of the final restoration. Variolink Esthetic Neutral does not affect the brightness value. At the same time, it demonstrates the highest translucency and is thus neutral in shade. Light and Light + make the restorations lighter, while Warm and Warm + create a darker overall shade impression. In order to evaluate the overall effect of the restoration in conjunction with the various Variolink Esthetic shades prior to permanent cementation, we recommend using the Variolink Esthetic try-in pastes.

Working time

The working and curing times depend on the ambient temperature.

The following times apply as soon as Variolink Esthetic DC has been extruded from the automix syringe:

When used purely self-curing

Room temperature 23°C ± 1°C/

73°F ± 2°F

Intraoral 37°C ± 1°C/

99°F ± 2°F

Working time                               approx. 5 min                     approx. 2 min

Setting time

(incl. working time)

approx. 8 min                     approx. 4 min

Mixing ratio

Variolink Esthetic DC is always dispensed from the automix syringe in the optimum ratio.

Composition

The monomer matrix of Variolink Esthetic is composed of urethane dimethacrylate and further methacrylate monomers. The inorganic fillers are ytterbium trifluoride and spheroid mixed oxide. Initiators, stabilizers and pigments are additional ingredients.

The particle size is 0.04–0.2 μm. The mean particle size is 0.1 µm. The total volume of inorganic fillers is approx. 38%.

Indication

• Adhesive luting of glass-ceramic, lithium disilicate glass-ceramic and composite restorations (inlays, onlays, partial crowns, crowns, bridges).
• Restorations made of opaque ceramics, e.g. oxide ceramics, can only be permanently cemented if an adhesive is additionally used that is separately light-cured.

• Variolink® Esthetic DC

• The use of the shades Light+ and Warm+ may lead to visible restoration margins when cementing inlays/onlays.

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.

Hemostatic substances may inhibit polymerization and/or lead to discolouration. Therefore, the directions for use of these substances must be observed.

Application

For more detailed information also refer to the Instructions for Use of the products used in conjunction with Variolink Esthetic.

1. 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.

1. 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.

Adequate relative or absolute isolation using suitable auxiliaries, such as OptraGate® or OptraDam® Plus, 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.
