Defining a new generation in permanent cements

ORANGE, CA - February 23, 2007 - For unprecedented advantages in dental esthetics, look no further. Introducing NX3 Nexus^® Third Generation, the new universal adhesive resin cement from Kerr. Universally indicated for all indirect applications - including veneers, NX3 is a permanent resin cement system with an
innovative chemistry for unmatched esthetics, adhesion and great versatility. Delivery systems choices
include an automix syringe for dual-cure indications and a light-cure cement for multiple units where unlimited work time is needed.

NX3 is compatible with self-etch and total-etch adhesives and obtains high bond strength whether the cement is light-cured or dual-cured. A dual-cure activator for the adhesive is no longer needed. And while lightcuring is always recommended even when there is limited light accessibility (i.e., PFM crowns), good adhesion is achieved in self-cure situations. NX3 adheres to all substrates - dentin, enamel, CAD/CAM blocks, ceramic, porcelain and metal.

"With Kerr's proprietary amine-free initiator system and optimized resin matrix, this product is the first truly color-stable adhesive resin cement on the market," says Kerr Product Manager Sue Seamon.

Versatility further distinguishes NX3. The dual-cure cement can be used for all indications including veneers, and for unlimited work time a separate light-cure cement for seating multiple units is available. With one set of try-in gels that match both dual-cure and light-cure cements and no color shifting, a huge advantage whenit comes to esthetic restorations, NX3 is one of the premiere products on the market today.

"NX3 solidifies our position in the cements arena by offering an option when esthetics and performance are of the utmost," says Director of Product Management Meghan Moore Rizzo. "If the success of Maxcem is any indication, Kerr clearly has an opportunity to provide a complete solution for all permanent cementation needs that clinicians can trust."

The full line of Kerr products is available from preferred dental distributors. For more information about how NX3 can improve the restorative process or to learn more about our broad portfolio of products, visit KerrDental.com, contact your local Kerr representative or call 800.KERR.123.
