Prevest Nano Coat Light Cure Protective Varnish

Nano Coat

Nanofilled Self Adhesive Light Cured Protective Coating, 1 x 5 mL

Is a single dispersion nano-filled protective coating for glass ionomer, composite and temporary restorations. The liquid glaze ensures improved aesthetics and increased strength, toughness and protection. It is designed for optimum wetting, strong adhesion, enhanced wear resistance and extra protection for margins. It provides a final lamination that aesthetically enhances all restorations with excellent colour stability and is the quickest way to finish all restorations.

Indications:

• To seal and protect the surface of glass ionomer, direct/indirect composite and provisional restorations.
• To seal and protect the adhesive interface between restorations and tooth structure.

Glass Ionomer Restorations

One quick application of Fusion Nano Coat reinforces and strengthens glass ionomer restorations. A protective coating of Fusion Nano Coat allows the complete maturation of the glass ionomer reaction and the delayed saliva exposure creates the strongest possible glass ionomer restorations. Infiltration of Fusion Nano Coat provides internal protection against cracks and voids to enable increased fracture toughness. On top of this, Fusion Nano Coat leaves an excellent smooth surface and un-matched exterior gloss.

Composite Restorations

One quick application of Fusion Nano Coat immediately transforms a newly contoured composite into a high gloss finished restoration. The tough self adhesive coating improves composite wear resistance and polish retention. Furthermore, as Fusion Nano Coat bonds to composite restorations as well as surrounding tooth surfaces, it will provide additional protection to composite – tooth margins.

Temporary Crowns

The quickest way to finish bis-acryl composite or acrylic temporary crowns is to simply apply Fusion Nano Coat and light cure. Fusion Nano Coat provides an excellent gloss finish that is both smooth and stain resistant.

Existing Restorations

Fusion Nano Coat adheres to existing restorations and can be used as a simple, easy to apply maintenance coating for demanding situations where extra wear resistance, acid resistance or polish maintenance is required. Fusion Nano Coat can be used to re-surface existing restorations that require servicing.

 Composition

Fusion Nano Coat contains Bis-GMA, Self Adhesive Monomers, Nano fillers in an acetone and MMA solution.

  • Spray preparation dust away with water. Dry by gently blowing with oil free air.
  • Surfaces to be coated should appear dry.
• Preparation of existing restorations
  • Roughen the surface to be coated with a superfine diamond bur.
  • Spray preparation dust away with water. Dry by gently blowing with oil free air.
  • Surfaces to be coated should appear dry.
• Preparation of marginal area
  • Non cut enamel should be treated with a 37% phosphoric acid according to the manufacturer’s instructions. Rinse an dry with oil free air.
  • Surfaces to be coated should appear dry.

B. Dispensing

• Should the coated surface be contaminated with water, blood or saliva prior to light curing, wash and dry the surface and repeat the coating procedure.

D. Light curing

• IMMEDIATELY light cure all coated surfaces with a visible light curing unit (> 500mW/cm2)
• Place the light source as close as possible to the coated surface.
