belleGlass The "next generation" of indirect composites, belleGlass NG, incorporates advanced nano-particle and submicron filler technology, creating the most significant development in composites in the last ten years, surpassing previous belleGlass benchmarks and setting new industry standards for polish, shine and wear. Developed by the same team of chemists and researchers who created Herculite, Prodigy and Point 4, today's standards for high quality direct composite materials. Light, heat and pressure produce the highest degree of material conversion (98.5%), giving belleGlass superior strength and wear characteristics. The opaceous dentin's high filler content exceeds 87%, providing exceptional strengths and shrinkage of less that 0.94%, which means better margin integrity and less chance of microleakage.       belleGlass NG System. Proven Clinical Performance. The opalescent appearance more closely characterizes natural enamel like no other composite based material. belleGlass restorations provide less wear to opposing dentition than porcelain because they are not as hard or abrasive. Studies from the University of Alabama have shown posterior restorations maintain polish and luster for 8 years, making it smooth, comfortable and long lasting. Natural look. The opalescent appearance more closely replicates natural enamel like no other composite-based material. With two bleaching shades (B0 and B00) and a complete range of Vita® classical shades, you can perfectly match the esthetic needs of every patient. Natural wear. belleGlass NG restorations closely match natural dentition in wear characteristics. High performance. Trimodal curing (light, heat and pressure) achieves over 98% material conversion, as compared with 60 - 70% achieved with light-cure-only materials. Long-lasting smooth polish. The unique blend of 25µ prepolymerized filler, 50 nm nanoparticles, and 0.4µ submicron hybrid fillers is a breakthrough of science and innovation. Particle sizes are below the wave-length of visible light, improving wear and delivering a surface that becomes smoother and shinier with time. Proven history. Rated #1 indirect resin system five years in a row by Reality Publishing, rated #1 by Dental Advisor, ten years of positive clinical studies and field data, and tens of thousands of successful restorations placed since 1996. Proven Longevity.
