During light-cured polymerization, resin monomers are in chaotic movement as they begin to bond with one another to form the polymer matrix. But the addition of the polymerization modulator controls the matrix formation and allows for a more relaxed network to form, avoiding 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
See the proof in this Stress Demonstration Video.
Our patented chemistry in SDR™ Technology features a new polymerization modulator that reduces polymerization stress by up to 60%. Stress that results from the contraction forces – or vectors – that occur when the composite undergoes volumetric shrinkage.
During light-cured polymerization, resin monomers are in chaotic movement as they move towards one another to form the polymer matrix. But in SDR™ Technology, the polymerization modulator controls the chaos and allows a more orderly, well-paced formation of the polymer network, absorbing stress as the curing continues – without marginal breakdown, post-op sensitivity, the formation of white lines, or cracks that are believed to occur with high-stress materials.
