C&B Metabond® Quick Adhesive Cement System
- Cement crowns on short or overly tapered abutments.
- Place direct pulp-caps, repair root perforations in “hopeless cases”.
- Re-cement bridges or posts that repeatedly loosen due to compromised retention or patient habits.
- Perform chairside repairs such as mending broken abutments, repairing porcelain fractures, splinting periodontally-compromised teeth, adding teeth to removable prostheses, or bonding directly to composite or acrylic-based prostheses.
C&B-Metabond® is still the one product that demanding clinicians reach for when they need solutions to “impossible” restorative dilemmas. This cement system has the unique ability to bond to just about any hard surface, whether it’s enamel, dentin, cementum, non-precious, semi-precious or noble alloys, porcelain, composite resin or acrylic.
C&B-Metabond is kind to hard and soft tissues because its time-proven formula incorporates biocompatible methacrylate resins along with its surface penetrating agent, 4-META. A surface-penetrating monomer, 4-META has the capacity to access vital or non-vital tubules and support the delicate collagen fiber network while it gets absorbed by the intratubular and peritubular dentin.
Our unique TBB catalyst ensures that C&B-Metabond will reliably set every time, whether it’s dark or moist, in all regions of the mouth. Upon curing, C&B-Metabond forms an acid-resistant hybrid layer that protects against post-op sensitivity and microleakage, while resin-reinforcing the dentin.
Most importantly, when you reach for C&B-Metabond, you can be confident that you’ve given the patient the greatest chance for case success, no matter how bad things seem. You truly may never have to re-cement that problem restoration again.
Frequently Asked Questions About C&B Metabond Quick
Q. Why is Parkell’s C&B Metabond Quick what dentists go to in difficult cases?
A. It is a self-cured adhesive resin cement designed to provide ultra-high strength. With appropriate pre-treatment it adheres to an exceptionally wide range of dental materials i.e., (enamel, dentin, cementum), dental metal alloys (base, precious and noble), amalgam, resin composites, acrylic resins, porcelains, lithium disilicate and zirconia.
Q. What are the different uses of Parkell’s C&B Metabond Quick?
A. It is indicated for the adhesive cementation of fixed dental prostheses such as inlays, onlays, crowns, conventional bridges, Maryland bridges, endodontic posts, as well as for emergency reattachment of fractured teeth, repair of porcelain fractures or pop-offs, adhesive pulp capping of small exposures, bonding of amalgam and many other challenging, low-retentive restorative or repair situations.
Q. When is pre-treatment indicated and what should I use?
A. Porcelain and Lithium Disilicate surfaces that have been etched with hydrofluoric acid and primed with Ea-Z-y Primer (available separately).
Zirconia that has been either sandblasted(some manufacturers advise against sandblasting) or using a Zirconia cleaner from another manufacturer, and primed with Ea-Z-y primer (available separately) will bond to C&B Metabond.
Non-precious metal alloy without special pretreatment other than sandblasting will bond tenaciously to C&B Metabond.
Precious and noble alloys that have been sandblasted and primed with MTL-V primer (available separately) significantly improves the durability of the bond.
Q. Is prelubrication necessary before using Parkell’s C&B Metabond Quick?
A. C&B Metabond cement sets extremely hard and sticks tenaciously to anything it touches. It must be cleaned up before it has completely set or removal will be very difficult. Water soluble lubricants such as K-Y jelly, Parkell’s Blu-Sep (available separately), or glycerin should be applied over any areas of concern before utilization. This will stop the cement from inadvertently sticking to neighboring teeth, gums or restorations and mixing wells.
Q. Can Parkell’s C&B Metabond Quick be used as an effective pulp capping material?
A. Yes. It is FDA certified for pulp caps and is more biocompatible than some other resin adhesives.
Q. Should I use the Universal Gel dental activator when pulp caping with Parkell’s C&B Metabond?
A. Yes. Because the Universal Gel dental activator contains ferric chloride, it can stop pulpal bleeding.
Q. What is the procedure to follow for pulp capping with Parkell’s C&B Metabond?
A. Apply the Universal Gel dental activator for 20 seconds to both the exposure and the surrounding dentin.
Rinse thoroughly, then lightly dry to eliminate standing water. DO NOT DISSICATE. Mix 1 to 1.5 scoops of the radiopaque powder to the already dispensed four drops of base and one drop of catalyst. Apply it to the exposure and the surrounding dentin. Allow Parkell’s C&B Metabond to set for at least 6 minutes before proceeding with any restorations.
Q. Will Parkell’s C&B Metabond adhere to surfaces that have had eugenol containing substances applied to them?
A. No. Do not use on surfaces that have been contaminated with eugenol (ZOE, etc.)
