Description
Repairing a Porcelain Veneer
​A fractured porcelain veneer can be immediately and predictably repaired chair-side with the use of composite resin and quality porcelain bonding techniques.
Before repair.                                               After repair.
Porcelain repair is growing in popularity because of improved techniques for treating porcelain. When done well, porcelain repair is a less invasive and more cost-effective way to extend the longevity of porcelain restorations. The Ultradent Porcelain Repair Kit contains all the products and tips needed for composite-to-porcelain, porcelain-to-metal, and porcelain-to-porcelain repairs.
. Includes all necessary precomposite-placement materials
. Yields high bond strengths
. Facilitates quick, easy repairs without mixing
. All chemistries in Ultradent Porcelain Repair Kit are certified gluten free
Technical Details
Viscous, Buffered 9% Hydrofluoric Acid
​Porcelain Etch is a buffered, gelled hydrolic acid designed specifically to etch fractured dental porcelain and etching porcelain veneers, crowns, or inlays. It can also be used for etching porcelain crowns before bonding orthodontic brackets. It is buffered and gelled to minimize any irritation that could occur from the hydrofluoric acid vapor.
Etch is Easy to Control and Place
​Porcelain Etch features a high visibility yellow hue so you can see exactly where it is placed. It is also viscous enough to stay where you place it.
Designed to Work Together
​Porcelain Etch and Silane are designed to be used together when etching porcelain to provide high porcelain-to-resin bond strengths. When used with a high-quality bonding resin, Porcelain Etch and Silane can produce one of the highest porcelain-to-resin bond strengths compared to other porcelain bonding products.

Procedures
Preparing the Porcelain
See Instructions for Use for complete instructions, warnings, and precautions.
Step 1
Etch clean bonding surface with Porcelain Etch for 90 seconds, rinse, and dry.
Step 2
CLINICAL TIP: Apply phosphoric acid (Ultra-Etchâ„¢ etchant) for five seconds to remove porcelain salts and debris formed by hydrofluoric acid etching. Rinse and air dry.
Step 3
​Apply a puddle coat of Silane to inside surface for 60 seconds, dry, and set prosthesis aside. Do not rinse.
