GC Gold Label 9 Extra Capsules are high-strength, radiopaque posterior glass ionomer restoratives designed for fast and efficient clinical use. Formulated with advanced Smart Glass filler technology, they offer improved translucency for more aesthetic restorations. As a true glass ionomer, it chemically bonds to tooth structure, features a tooth-like coefficient of thermal expansion, and provides sustained, rechargeable fluoride release for long-term protection. The capsule format ensures precise powder-liquid ratio with no manual measuring, enabling consistent mixing, reduced porosity, and stronger restorations. Its fast-setting, non-shrink formulation allows single-step placement without layering, while high compressive and flexural strength ensures durability in posterior applications. Reduced moisture sensitivity and excellent handling make it a reliable choice for everyday restorative procedures.
