GC Fuji Gold Label 9 is a high-strength, strontium-reinforced glass ionomer restorative, designed for use in posterior teeth. It combines the benefits of traditional glass ionomers with improved physical properties to support long-term performance.
The inclusion of strontium glass enhances radiopacity and provides a quick setting behavior ("snap set") favored by practitioners. Strontium also plays a role in remineralization, forming compounds within the tooth similar to natural hydroxyapatite, helping to reinforce tooth structure from within.
In the oral environment, calcium from saliva interacts with the glass ionomer to create a surface-strengthening effect. Over time, this leads to increased durability. Additionally, GC Fuji Gold Label 9 forms a chemical bond with tooth tissue, creating a reliable and long-lasting seal through ion exchange.
