Using EtchArrest neutralizer during porcelain restorations
EtchArrest acid barrier/neutralizer protects adjacent porcelain and soft tissue from hydrofluoric acid. For situations where dentin/enamel are present in a preparation, use Ultra-Etch™ etchant phosphoric acid first to etch the tooth, then hydrofluoric acid second to etch the porcelain. This will ensure that dentin/enamel bond strengths are not compromised. Hydrofluoric acid will reduce adhesion to dentin and enamel, so EtchArrest neutralizer prevents accidental migration onto tooth structure.
Protects Bond Strengths During Porcelain Repair Procedures
When hydrofluoric acid contacts enamel during porcelain repair procedures, formation of calcium fluoride occurs and bond strengths to enamel drop significantly.1 Therefore, it is vital to treat porcelain and tooth structure separately with appropriate acids. EtchArrest neutralizer isolates hard and soft tissues when rubber dam placement is not practical.
Neutralizes Etchants on Contact
EtchArrest neutralizer contains sodium bicarbonate and calcium to neutralize the acids in etchants. This allows EtchArrest neutralizer to create a protective barrier around the area needing to be etched, and to easily neutralize the acids when etching time is reached.
Protects Soft Tissues and Nearby Restorations
Nearby teeth and gum tissue should always be covered when using acids. The viscous, acid-neutralizing EtchArrest ensures that nearby tooth structure and membranes remain protected during the etching process.
EtchArrest neutralizer features a dark purple tint that is easily seen against both etchants and mouth tissues.
When EtchArrest neutralizer is mixed with etchant, the acids in the etchant are neutralized. This allows you to clean the mixture out of the mouth without fear of spraying acids onto delicate tissues. The mixture is easily rinsed off with water.
