Instructions for using cobalt porcelain acid etching

Product Description:

• Cobalt Etched Porcelain is a hydrofluoric acid gel with a special polymer gelling agent, which gives the gel an ideal viscosity. Applying hydrofluoric acid to the surface of dental porcelains creates surface roughness, increases the free energy of the porcelain surface and improves its wettability by cement. Therefore, this material is used on the inner surface of dental porcelains such as crowns and veneers, and causes better penetration of cement into the created porosities and increases bond strength.
• Cobalt-etched porcelain has similar effects to sandblasting, but is more controlled and effective. Hydrofluoric acid also creates hydroxyl bonds on the porcelain surface, which, after application of silane coupling agents, creates a chemical bond to the resin cement.

Advantages:

• Easy placement and control
• No staining on composite and ceramic
• Quick and easy washing
• Cobalt-etched porcelain is available in two concentrations: 6 and 9 percent. The desired acid is selected based on the type and material of the restoration.

Uses:

Before cementing porcelain restorations including veneers, inlays, onlays and crowns Repairing defective porcelain restorations Before bonding orthodontic brackets to porcelain crowns

Method of use:

If using cobalt-etched porcelain to repair defective porcelain restorations, lightly freshen the desired surface before applying the gel using a turbine bur and apply the acid to the surface for 90 seconds. In the next step, rinse the acid thoroughly. After drying the surface, ensure that a gypsum surface is formed on the porcelain. Finally, continue the bonding steps by applying silane according to the manufacturer’s instructions. In the case of cementing porcelain restorations, completely soak the inner surface of the restoration with cobalt-etched porcelain. Depending on the type of porcelain, rinse the acid after 30 to 120 seconds. If the porcelain surface does not have a gypsum appearance, repeat the process. When using this product intraoral, it must be used with full protection protocol (use of rubber dam and protective glasses).

Clinical tips during work:

Avoid re-etching porcelain restorations that have been etched in the laboratory. This can weaken the restoration. Avoid using porcelain etch on a glazed tooth surface. This product can cause surface roughness and reduce its luster. Test the gel on a glass pad or slab before use to familiarize yourself with the amount of pressure required to expel the gel from the syringe, otherwise too much gel may be expelled.

If the gel is difficult to get out of the syringe, replace your needle tip.

After working with acid gel, replace the needle tip and close the syringe cap. This will extend the life of the product. This product is designed for dental use only.

Warning:

Hydrofluoric acid is a very dangerous and harmful chemical. Therefore, when using this product: If you accidentally splash this product into your eyes, rinse your eyes immediately with plenty of water and see a doctor. This product also releases a large amount of toxic vapor. Therefore, avoid prolonged exposure to this product. When using this product, be sure to wear goggles and gloves. If you use this product in the patient’s mouth, be sure to use a rubber dam. Leaving this product on the skin or mucous membranes can cause damage, so if it comes into contact with soft tissue, wash the acid off immediately. This product cannot be used as an enamel and dentin etchant. Take special care not to swallow the product. If you intend to use this product in the patient’s mouth, test the substance on a slab before psychiatric use to familiarize yourself with the amount of pressure required for the acid to exit the needle tip. Close the product after use. If the acid is left open in the syringe for a long time, the viscosity of the acid will increase and become unusable.

Storage conditions:

Store at 5 to 25°C. Do not use after the expiration date.

Avoid exposure to direct sunlight.
