Ultradent, Porcelain Etch Refill

Ultradent's Porcelain Etch Refill is a dental product designed for etching porcelain surfaces in dental procedures. It consists of a viscous, buffered 9% hydrofluoric acid solution. The product is specifically formulated to etch porcelain veneers, crowns, bridges, inlays, onlays, and fractured dental porcelain​​.

Key Features:

1. Buffered Hydrofluoric Acid: The Porcelain Etch contains a buffered, gelled hydrofluoric acid, making it suitable for etching various porcelain dental restorations.
2. High Visibility and Control: It has a high visibility yellow hue, allowing precise application, and its viscous nature ensures that it stays in place.
3. Compatibility: Besides traditional porcelain, it can also be used on lithium disilicate (IPS e.max) restorations.
4. Non-Staining: The formulation is designed to not stain composite or resin cement, ensuring clean and predictable outcomes​​.
5. Intraoral and Extraoral Use: Suitable for both intraoral and extraoral applications, but when used intraorally, protective measures like a rubber dam or EtchArrest are necessary​​.

Usage Instructions:

1. Etching: Apply the Porcelain Etch on the clean bonding surface for 90 seconds, followed by rinsing and drying.
2. Cleaning: Optionally, apply phosphoric acid (like Ultra-Etch) for five seconds to remove any residual porcelain salts or debris, then rinse and air dry.
3. Silane Application: Post etching, apply a puddle coat of Silane to the inside surface for 60 seconds, dry, and set the prosthesis aside without rinsing​​.

Conclusions:

Ultradent's Porcelain Etch Refill is a high-performance etching agent that provides dentists with a precise, controlled, and effective way to prepare porcelain surfaces for bonding. Its high bond strength, compatibility with various porcelain and silica-based materials, and non-staining properties make it a valuable asset in restorative dental procedures. By incorporating this product, dental professionals can achieve optimal outcomes in porcelain restoration, enhancing both the aesthetics and longevity of dental prosthetics.
