A Strontium-Based Glass Ionomer

All GC Gold Label Glass Ionomers contain strontium glass, which provides excellent radiopacity and sharp set characteristics, making them a preferred choice for clinicians worldwide. Strontium also mimics calcium in forming strontium hydroxyapatite and strontium fluoroapatite, contributing to internal remineralization within the tooth structure.

Surface Strengthening Effect

Research indicates that when a strontium-based glass ionomer is placed in a calcium-containing environment, such as saliva, calcium ions diffuse into the glass ionomer surface, resulting in a strengthening effect. Over time, all GC Gold Label Glass Ionomers continue to strengthen in the presence of saliva, enhancing durability.

A Consistent, Predictable Seal

GC Gold Label Glass Ionomers develop a glossy surface immediately after mixing, indicating that sufficient free polyacrylic acid is present to initiate the ion exchange process. The movement of ions between dentin, enamel, and the glass ionomer forms an ion exchange zone, chemically fusing the materials together. This creates a consistent, predictable, and long-lasting seal.

Indications

• Cementation of metal or porcelain-fused-to-metal crowns, bridges, and inlays
• Cementation of stainless steel crowns or orthodontic appliances retained with stainless steel crowns
• Cementation of orthodontic bands
• Use as a base or liner

Advantages

• Requires minimal cavity preparation
• Reduces stress on margins while maintaining marginal seal
• Protects against secondary caries
• Promotes internal remineralization and surface strengthening
• Allows easy post-operative diagnosis
• Simple mixing and sharp setting for convenient handling
• Final finish achievable under water 15 minutes after mixing
• Excellent color match with natural tooth structure
• Produces durable, long-lasting restorations
• Ensures successful clinical outcomes

• In case of contact with eyes, flush immediately with water and seek medical attention.
• DO NOT mix powder or liquid with any other glass ionomer components.

Gc Gold Label 1 Glass Ionomer Mini Pack:

• 1 x 15g Powder
• 1 x 10gm Liquid

Gc Gold Label 1 Luting And Lining Big Pack:

• 1 x 35g Powder
• 1 x 25gm Liquid

Step 1: Mix the cement to the correct powder-to-liquid ratio. For Gold Label 1, mixing time is approximately 20 seconds.

Step 2: Apply the mixed cement to both the restoration and the prepared tooth surface.

Step 3: Seat the restoration within 30 seconds of completing the mix.

Step 4: Remove any excess cement during the gel stage.

Note: Total setting time is approximately 4 minutes 30 seconds from the start of mixing.

Step 5: After the final set, protect the margins by applying a final coat of GC Fuji Varnish or GC Fuji Coat LC to moisture-proof the restoration.
