All core materials are not equal. CompCore AF Dual-Cure recently was awarded four and one-half stars by The Dental Advisor and was named as one of the top products of 2003. In celebration of the continued recognition for CompCore AF Dual-Cure and to introduce new dentists to this outstanding product, Premier is offering an exceptional introductory offer.

CompCore AF Dual-Cure Intro Kit contains a 50gm auto-mix cartridge of composite core material, 4ml bottles of IntegraBond and Auto-Cure Activator, system compatible adhesives, and the auto-mix dispenser gun. Now, each introductory kit also contains a FREE Cartridge ($115 USD value) attached to the box
(Figure 1).

CompCore AF Dual-Cure represents a new class of advanced restorative composite materials. It is the first dental material to contain a patented booster molecule characterized by a hyperbranched, dendritic configuration that creates multiple contact sites for more complete free-radical polymerization and enhances the physical properties of conventional bis-GMA. Conventional composite core bis-GMA material polymerizes in a linear chain with significantly less cross-linking (Figure 2).

The end result is a superior compressive strength, higher elastic modulus, and significantly reduced composite shrinkage. The LED-compatible formula makes it uniquely suited to fast, accurate and long-lasting core build-ups.

CompCore AF Dual-Cure contains many additional product features like true fluoride release and a time-saving, auto-mix dispensing system. The material has good flow, is stackable, and creates a dense void-free core that preps like natural tooth structure. The superior physical properties of CompCore AF Dual-Cure are supported by an independent study from Creighton University, specifically attesting to the material's low shrinkage and high strength.

Case Presentation

Etch the entire cavosurface with a 32% to 40% phosphoric acid for 15 second, (for post preparation, the canal and cavosurface can be etched at the same time,) (Figure 3).

Premier® Etch is 37% phosphoric acid. Rinse the etchant by spraying water on it for 15 seconds. Etched enamel should appear frosted (Figure 4).

Blot dry the etched enamel and rinsed surfaces with paper points (Figure 5).

Mix one drop each of Auto-Cure Activator with IntegraBond in a clean mix-well for 2 seconds (Figure 6).

The mixed components increase bond strength to dual-cured composites like CompCore AF. Apply the first coat over the entire cavosurface (Figure 7).

Allow IntegraBond mixture to sit for 15 seconds. Remove the solvents with a blast of air (Figure 8).

Apply the second coat and immediately blow off the solvents. Apply subsequent coats and continue to blow the solvents off after each coat (Figure 9).

Look for light reflectivity (a shining surface) for a cue to sufficient coating. (Multiple coats are necessary because the activator dilutes the adhesive.) After the final application of bonding agent/activator, light-cure the prepared surface for 20 seconds (Figure 10).

This step is important for adhesive compatibility with the self-cure initiators in dual-cure composite core materials. Place an intra-oral tip into the base of the prepared tooth and dispense an adequate amount of material to complete build-up. This should take almost 2-1/2 minutes (Figure 11).

Express the material while withdrawing the tip to eliminate air bubbles. Premier ACCOR® crown forms, included in the CompCore AF Introductory Kit, can be used as a matrix for the build-up. Do not disturb CompCore AF after syringe placement. Light-cure Comp-Core AF for 40 to 50 seconds. Chemical-cure should take almost 3-1/2 minutes (Figure 12).

Check for hardness and finish the preparations with a Two Striper® (Premier Dental Products Company) diamond or rotary instrument of your choice.

Conclusion

Many products available work equally well. Product choice is often dependent upon a combination of factors including price, manufacturer's reputation, supporting research, recommendation from a colleague or peer-review journal, and ease of use. Easy to use does not necessarily mean fewer application steps. It implies a comfort level with technique based on an understanding of processes and materials. In addition to all these factors, a product should be judged on the quality of patient care it allows. CompCore AF Dual-Cure is an innovative composite core material that will provide consistent and successful restorative outcomes for your patients.
