PANAVIA V5 is an adhesive resin cement system. The Paste is a dual-cure, fluoride-releasing, radiopaque resin cement for ceramics (lithium disilicate, zirconia, etc.), hybrid ceramics, composite resins, and metal restorations. The Panavia V5 Tooth Primer is a self-etching primer that accelerates the polymerization of the Paste. Prior enamel etching is optional, but necessary for veneers and adhesive bridges. Use: Apply Primer to the entire prepared tooth (tooth, metal, composite resin), leave in place for 20s, remove excess with a cotton pellet, thoroughly gently air-dry.
