Ultra-Etch etchant is a 35% Phosphoric Acid solution
Uses: - Ultra-Etch etchant is indicated for use on dentin and enamel to create optimal bonding surfaces. - Ultra-Etch etchant can also be used to remove contaminants from composite on porcelain prior to bonding. (Note: don’t use phosphoric acid on metal or zirconia, as this will reduce bond strength)
Ultra-Etch is self-limiting in its depth of etch (average depth of 1.9 micrometer with 20-second etch), creating an etch pattern that adhesives can penetrate for increased bond strength and reduced sensitivity. Studies demonstrate that Ultra-Etch’s unique self-limiting chemistry creates an optimal surface to receive resin. Though Ultra-Etch is viscous, it can penetrate into the smallest fissures or occlusal surfaces due to physical and chemical properties that promote capillary action. Its ideal viscosity maintains a layer thick enough to prevent premature drying.
With an average depth of 1.9?m with a 15-second etch, Ultra-Etch stops etching at the ideal depth.
Features: - It features ideal viscosity - Self-limiting on dentin - Penetrates smallest fissures but won’t migrate on a vertical surface - Increases bond strength and reduces sensitivity - Places precisely and rinses clearly - Rinses cleanly—leaves no residue
