Tokuyama Bulk Flow Syringe Refills offer a high-performance, light-cured, radiopaque composite resin for efficient dental restorations. With low viscosity, these syringe refills provide easy handling and placement in 4mm increments. Featuring Radical-Amplified Photopolymerization (RAP) initiator technology, the material ensures a shortened light-curing time and extended working time, enhancing procedural efficiency. The composition includes a significant 70% by weight (56% by volume) of spherical silica-zirconia filler, minimizing polymerization shrinkage stress and promoting excellent gloss retention and wear resistance. The composite filler, with a mean particle size of 200nm, further contributes to enhanced properties. Available in shades U (Universal), A1, A2, A3, and B1, the syringe refills are versatile for various restorative applications, including direct anterior and posterior restorations, cavity lining, and repair of porcelain/composite. Contraindications advise against use for patients allergic to methacrylic and related monomers. Each syringe refill is designed for optimal dispensing and ease of use during dental procedures, ensuring reliable and aesthetically pleasing outcomes.
