Description

Bisco Porcelain Etchant 9.5%

Bisco’s Porcelain Etchant 9.5% is a gel-based solution containing hydrofluoric acid, tailored to optimize the bond between porcelain and resin cements. With a precise 9.5% concentration, it effectively enhances the adhesive strength by etching porcelain surfaces. This specialized etchant increases the surface area of porcelain, akin to controlled sandblasting, promoting robust bonding with composite resin materials. Available in a convenient syringe format, its application is precise and hassle-free. Bisco’s Porcelain Etchant offers dental professionals a reliable means to achieve durable bonds in their restorations, ensuring optimal performance and longevity. By microscopically roughening porcelain or glass surfaces, it facilitates superior mechanical bonding, enhancing the overall quality and longevity of dental restorations.

The principle use of 9.5% Porcelain Etchant is for etching porcelain prior to:

• Cementation of porcelain restorations.
• Repair of porcelain restorations.

Key Features

• Porcelain Restorations: Indicated for cementation of porcelain restorations and repair of porcelain restorations.
• Improves Bond Strength: Improves the mechanical bond between porcelain and adhesive/cement by increasing the surface area of the porcelain. The effect is similar to sandblasting but is more controlled and effective.
• Improved Bonding Strength: Increases the surface area of porcelain, facilitating a strong and durable bond with composite resin materials.
• Controlled Application: Comes in a gel form and a convenient syringe format, allowing for precise and controlled application.
• Microscopic Roughening: Microscopically roughens the feldspathic porcelain or glass surface, enhancing mechanical bonding.
• Comparable to Sandblasting: Provides similar effects to sandblasting but in a more controlled and effective manner.
• Enhances Restoration Longevity: Promotes robust bonding, contributing to the longevity and durability of dental restorations.

Directions for Use

Etching Porcelain Restorations prior to cementation:

• Protective eyewear and gloves must be worn by operator and assistant.
• If the labs has not already etched the restoration, remove cap from Porcelain Etchant, securely attach dispensing tip and verify etchant flow prior to application. Apply Porcelain Etchant (9.5% HF) to the dry porcelain surface for 90 seconds. Care must be taken to avoid having the etchant contact glazed porcelain surfaces since these surfaces will lose their gloss.
• Rinse with a copious amount of water and air dry. The etched surface should appear dull and frosty (if porcelain has a white/ chalky appearance, agitate a moist microbrush on the porcelain to remove salt and debris created by etching).
• Apply one to two thin coats of silane with a brush to the etched internal surface of the restoration according to manufacturer instructions. Dry with air syringe.
• Proceed with adhesive applications and cementation according to the manufacturer’s instructions.

Repair of Porcelain Restorations:

• Protective eyewear must be worn by patient, operator and assistant. Protective gloves must be worn by operator and assistant.
• Remove the glaze and bevel (45 degree) the porcelain around the area to be repaired. (Remove any old composite remaining from previous repairs).
• Isolate the area to be etched with a rubber dam. Bisco’s Barrier Gel should be placed where etching is not desired.
• Remove cap from Porcelain Etchant, securely attach dispensing tip and verify etchant flow prior to applying intraorally. Apply Porcelain Etchant then rinse with a copious amount of water and air dry. The etched surface should appear dull and frosty (if porcelain has a white/ chalky appearance, agitate a moist microbrush on the porcelain to remove salt and debris created by etching, rinse and dry).
• Apply one to two thin coats of silane with a brush to the etched surface of the restoration and allow to dwell for 30 seconds. Dry with air syringe.
• Apply an adhesive system according to the manufacturer’s instructions. Complete the repair with composite and finish/ polish.
