New Premise Flowable Composite Features High Radiopacity and Ultra-Low Shrinkage

ORANGE, CA - May 2007 - Kerr Corporation is pleased to announce the availability of its award-winning Premise™ trimodal hybrid composite in a flowable configuration. With its optimized viscosity, new Premise Flowable strikes an ideal balance between ease of dispensing and handling. It flows easily to fill cavities, yet holds its shape.

In addition to its superior handling characteristics, Premise Flowable offers a number of tangible benefits for direct applications. The Kerr proprietary trimodal filler system delivers excellent mechanical strength, superior polishability and wear resistance. Premise Flowable offers over 300% radiopacity - the highest percentage of any flowable composite currently on the market - and 20% less shrinkage than leading brands to minimize stress, sensitivity and microleakage.

Available in a choice of 10 shades for enhanced esthetics, Premise Flowable is indicated for anterior and posterior applications, including temporary and permanent repairs, sealant and base/liner. Each shade comes in a 1.7 gram net weight syringe with single-use metal dispensing tips.

The full line of Kerr products is available from a preferred Kerr dealer. To learn more about Premise and our broad portfolio of products, visit KerrDental.com, contact your local Kerr representative or call 800.KERR.123.
