Yellow Porcelain Etch (hydrofluoric acid in gel) and Silane allow reparation of the dentures in the dental office, directly in the patient’s oral cavity. The etch is used for porcelain etching during reparation of the dentures in the patient’s oral cavity, as well as for the etching of the porcelain vaneers, crowns or inlays before their cementation.
Silane is applied on the porcelain after etching and before use of bonding system.
Both preparations are packaged in handy syringes with suitable brush applicators.
Dense, gelly and yellow etch contains fluoric acid, buffered in such a way that no noxious vapours are leaching to the air (what is possible in case of etches intended for use by technicians). Thanks to that porcelain can be etched in the oral cavity of the patient. In case of using it in the oral cavity it is recommended to protect the soft tissues.
Method of use:
Before the treatment immerse attached applicator in alcohol (ethyl alcohol) and then fix it onto the syringe.
1. Isolate the treatment field with a rubber dam.
2. Screw the elastic blue applicator on the syringe with the etchant, replacing the safety plug with this applicator.
3. Apply a small amount of etching preparation on the prepared and dried surface. Immediately close the syringe with the safety screw.
4. Leave the etching preparation on for 60 seconds and then rinse and dry the procedure area.
5. Apply Silane.
