90-Second Etch—60-Second Silane Ultradent Porcelain Etch is a viscous, buffered 9% hydrofluoric acid.
Silane is a single-component solution.Ultradent 90-second Porcelain Etch is used to etch porcelain veneers,crowns, bridges, inlays, onlays, and fractured dental porcelain.
Ultradent 60-second Silane is used after hydrofluoric acid etching to prepare the surface for bonding resin.
Studies have demonstrated that Silane, when used with Porcelain Etch and a quality bonding resin,yields the highest bond strength to porcelain when compared with other porcelain bonding products.
1 Both Porcelain Etch and Silane may be used intraorally or extraorally.
Uses Porcelain Etch is designed for intraoral or extraoral porcelain etching.
Use it to etch porcelain or old macrofilled composites prior to bonding and repair.
Also use it when in-office etching of indirect restorations,such as veneers, inlays, etc., is required.
After porcelain etching,clean residual debris with Ultra-Etch® etchant for 5 seconds and rinse thoroughly; follow with Silane application.
