Breakthrough SDR™ Technology
Advanced Chemistry reduces polymerization stress by up to 60%.
During light-cured polymerization, resin monomers are in chaotic movement as they begin to bond with one another to form the polymer matrix. The addition of the modulator leads to the formation of a more relaxed network, minimizing the build-up of stress. Not only does that make a bulk-fill flowable base possible, it helps alleviate or eliminate problems associated with polymerization stress. So, restorations will be faster and more efficient.
What problems are believed to be associated with high-polymerization stress?
- Marginal integrity issues
- Enamel fracture
- Cracked cusps
- Failure of the composite-tooth surface
- White lines around the restoration
- Gaps that cause post-operative sensitivity, microleakage and/or secondary caries

With SDR™ Technology, a “Polymerization Modulator” was chemically embedded in the polymerizable resin backbone of the SDR™ resin monomer. Based on scientific evidence gathered to date, the “Polymerization Modulator” in SDR™ resin reduces stress build-up upon polymerization without a reduction in the polymerization rate or conversion. Through the use of the Polymerization Modulator, the SDR™ resin forms a more relaxed network and provides significantly lower polymerization stress than any other conventional resin.
