ReVeneer™—A New Chairside System for Ceramic Fracture Repair

ReVeneer™ is a new system for repairing ceramic fractures in the mouth. The system developed by SCHUTZ Dental Group, Inc (Rosbach, Germany), uses only a primer, repair paste, and composite. ReVeneer requires no acid-etching, so it is safe for intraoral use. The advantages of the system are high bond strength, ease of use, and that it works with all conventional curing lamps and composite systems. ReVeneer is available direct from the manufacturer or through a local distributor.

ADVANTAGES OF REVENEER

There are many advantages of choosing ReVeneer. The system:

• uses no acid-etching, so it is safe for intraoral use;
• needs no silane;
• has extremely high bond strength;
• is fast—takes less than 5 minutes for a full repair, even down to the metal;
• is compatible with all-ceramic systems;
• can be used with all conventional curing lights; and
• can repair a ceramic fracture, down to the metal, intraorally.

With more and more porcelain restorations being placed every year, it is only natural that fractures occur. Typically ceramic fractures, especially down to the metal, are traditionally removed (which causes more damage) and then sent back to the laboratory for repair. This results in extra work, cost, and time for the patient, dentist, and laboratory. ReVeneer allows these fractures to be fixed easily and economically at chairside. A full repair, even down to the metal (Figure 1), can be completed in less than 10 minutes.

To begin the repair, smooth the damaged surfaces and roughen with a diamond bur or intraoral sandblaster. Remove all leftover bonding material with oil-free compressed air. Using a brush, apply a thin coat of primer to the ceramic or any exposed metal immediately after cleaning (Figure 2). Allow to air-dry for approximately 1 minute. Make sure the treated surface is dry.

When the ceramic fracture extends to the metal frame, the ReVeneer opaquer is now applied to mask this dark surface. If the fracture to be repaired is only on the porcelain surface, this step can be eliminated. Using a hard, short-haired brush, apply a thin layer of opaque (Figure 3). At least two coats are necessary to achieve total coverage; light-cure each layer for 60 seconds.

The ReVeneer base is now placed to improve the adhesion between the ceramic (or opaque) and the composite layer. The base is applied with a syringe and is a light green color to indicate coverage area. After the placement of the base, be careful to brush a thin layer over the entire surface to be repaired (Figure 4). After light-curing for 40 seconds, the light-green paste will turn clear to indicate complete polymerization.

Finally, a layer of composite is placed and cured directly over the repaired area. This can be done with the ReVeneer composite or any other system. There is no need for any further etching or bonding before composite placement. Follow the manufacturers’ curing and polishing instructions (Figure 5).
