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 LC

  • Permanent cementation of glass-ceramic, lithium disilicate glassceramic and composite restorations (inlays, onlays and veneers)
  • Only for restorations with a low material thickness of <2 mm and sufficient translucency (e.g. IPS e.max HT).

Shades:

  • Light, Neutral, Warm

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.

  1. Pre-treatment of the restoration
    1. 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 brush.
      • Leave Ivoclean to react for 20 s, then thoroughly rinse with water spray and dry with oil-free air.
      • Next, prime the bonding surface of the restoration with a suitable bonding agent (e.g. Monobond® Plus).

Make sure to observe the Instructions for Use of the bonding agent used.

    1. that have not been pre-treated by the dental laboratory should be rinsed with water spray and dried after the try-in procedure.
      1. condition the bonding surface of the restoration as follows:
        1. 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.
        2. 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.
        3. Zirconium oxide (e.g. IPS e.max ZirCAD) or aluminium oxide ceramics
          • Sandblast the bonding surface (sandblasting parameters 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.
          • IMPORTANT! In order to create a strong bond, do not clean the zirconium oxide surfaces with phosphoric acid.
      2. 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.

 

      • Following try-in, thoroughly rinse the restoration with water spray and dry with oil- and moisture-free air.
      • Apply Monobond Etch & Prime on the bonding surface using a microbrush and agitate it into the surface for 20 seconds. Allow to react for another 40 seconds.
      • Thoroughly rinse off Monobond Etch & Prime with water spray until the green colour has disappeared. If any residue remains in the microporosities, the restoration may be cleaned with water in an ultrasonic unit for up to 5 minutes.
      • Dry the restoration with a strong stream of oil- and moisture-free compressed air for approx. 10 seconds.
    • and fiber-reinforced composite restorations should always be conditioned according to the instructions of the manufacturer of the restorative material. With Tetric® CAD restorations, please observe the instructions stated in the Tetric CAD Instructions for Use.
  1. Pre-treatment of the preparation and application of the adhesive (e.g. Adhese® Universal)

Please observe the Instructions for Use of the adhesive used.

    • Conditioning with phosphoric acid gel (optional)

The bond to enamel can be improved by selectively etching the enamel or by applying the ”etch & rinse“ technique. Unprepared enamel surfaces must be conditioned with phosphoric acid (e.g. Total Etch). Please observe the Instructions for Use for the phosphoric acid gel.

  1. Selective enamel etching

Apply phosphoric acid gel (e.g. Total Etch) onto the enamel and allow it to react for 15–30 s. Then rinse thoroughly with a vigorous stream of water for at least 5 s and dry with compressed air until the etched enamel surfaces appear chalky white.

  1. Etch & rinse technique

Apply phosphoric acid gel (e.g. Total Etch) onto the prepared enamel first, and then to the dentin. The etchant should be left to react on the enamel for 15–30 s and on the dentin for 10–15 s. Then rinse thoroughly with a vigorous stream of water for at least 5 s and dry with compressed air until the etched enamel surfaces appear chalky white.

    • Application of Adhese Universal
      • Starting with the enamel, thoroughly coat the tooth surfaces to be treated with Adhese Universal.
      • The adhesive must be scrubbed into the tooth surface for at least 20 s. This time must not be shortened. Applying the adhesive on the tooth surface without scrubbing is inadequate.
      • Disperse Adhese Universal with oil- and moisture-free compressed air until a glossy, immobile film layer results.

Important note: Avoid pooling as this may compromise the accuracy of fit of the definitive restoration.

      • Light-cure Adhese Universal for 10 s using a light intensity of

≥500 mW/cm² (e.g. Bluephase® Style).

  1. Seating of the restoration
  • For each application place a new mixing tip on the syringe. Dispense Variolink Esthetic DC from the automix syringe and apply the desired quantity directly to the restoration.

As the luting material will cure in the used mixing tip, it serves as a seal for the remaining contents of the syringe until needed again (replace with a new tip before the next use).

  • Variolink Esthetic DC should be processed quickly after extrusion from the automix syringe and the restoration seated into place. Apply Variolink Esthetic DC directly to the internal surface of the restoration. Note: Direct application of Variolink Esthetic DC to a preparation that has been pre-treated with adhesive may - depending on the adhesive used - lead to an acceleration of the curing process and affect the accuracy of fit of the restoration.
  • Seat the restoration and fix/hold it in place during excess removal.
  • Remove all excess luting material.
