Ultra-Etch is a 35% phosphoric acid solution. It features ideal viscosity, which along with the use of the Blue Micro or Inspiral Brush tip, facilitates precision placement and superior control. Contemporary studies demonstrate Ultra-Etch is the optimum "total etch" etchant. Ultra-Etch is self-limiting in its depth of etch (average depth of 1.9μm with 20-second etch):
1. 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.
2. 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.
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
Indications for Use
Ultra-Etch can be placed in any location, including lingual approaches to Class III restorations. It works nicely for etching before bonding composites, sealants, or adhesives.
Self-Limiting Chemistry Creates Optimal Surface
With an average depth of 1.9μm with a 15-second etch, Ultra-Etch stops etching at the ideal depth.
