Product Details
GC Gold Label Glass Ionomer is a high-strength, strontium-based restorative material that delivers all the essential properties of traditional glass ionomers, with physical characteristics robust enough for use in posterior teeth.
As a Strontium-based Glass Ionomer, all GC Gold Label products contain strontium glass, which contributes to good radiopacity and snapset qualities, making it a preferred choice among clinicians worldwide. Strontium has the ability to mimic calcium in forming strontium hydroxyapatite and strontium fluoroapatite, promoting internal remineralization within the tooth structure.
Research has demonstrated that when a strontium-based glass ionomer is placed in a calcium-rich environment, such as saliva, calcium ions are able to diffuse into the material, resulting in a surface-strengthening effect. Over time, GC Gold Label Glass Ionomer continues to strengthen within the saliva, enhancing its durability.
GC Gold Label Glass Ionomer also ensures a consistent, predictable seal. After mixing, the material will display a glossy surface, indicating that sufficient free polyacrylic acid is available to initiate the ion exchange process. This leads to a chemical fusion between the dentin, enamel, and the glass ionomer, creating a long-lasting, reliable bond.
Indications:
- Class I and small Class II restorations in non-load bearing areas
- Class I and Class II restorations in deciduous teeth
- Transitional restorations
- Base / Core build-ups
Features
The chemical adhesion of GC Gold Label 9 to tooth structure enables minimal cavity preparation, eliminating the need for etching or bonding agents. This simplifies the restorative process and minimizes the preparation steps.
The material sets chemically without shrinkage, allowing for single-step placement without the need for layering. This feature streamlines the procedure and enhances efficiency.
GC Gold Label 9 also has a similar thermal expansion to tooth structure, which reduces the stress on the marginal seal and helps maintain the integrity of the restoration over time.
The strontium-based glass in this material provides excellent radiopacity and snap-set characteristics, qualities that are consistently preferred by clinicians. This ensures that the restoration is easy to visualize on radiographs and sets quickly for optimal handling.
The strontium-based, fluoride-releasing formulation contributes to internal remineralization within the tooth structure. Additionally, it increases the surface strength of the restoration over time, providing long-term benefits for the tooth.
With high compressive and flexural strength, as well as 60% greater wear resistance compared to conventional glass ionomers, GC Gold Label 9 is strong enough for use in posterior teeth, making it an ideal choice for durable and reliable restorations.

Directions To Use
1. Powder and Liquid Dispensing
The standard powder-to-liquid ratio is 3.4g of powder to 1.0g of liquid (1 level scoop of powder to 1 drop of liquid). To dispense the powder accurately, lightly tap the bottle against your hand. Do not shake or invert the bottle. For liquid dispensing, turn the bottle upside down, keeping the nozzle away from the mixing pad, and gently press the bottle. Discard the first 1-2 drops after opening a new bottle, as the dispensed amount may not be accurate. Be sure to close the bottles tightly immediately after use.
2. Mixing
Place the powder and liquid onto the mixing pad. Using a plastic spatula, divide the powder into two equal portions. Mix the first portion with all the liquid for 10 seconds. Then, incorporate the remaining powder and mix the entire mixture thoroughly for 15-20 seconds (Fig. 1).
3. Restorative Technique
Prepare the tooth using standard techniques, as extensive mechanical retention is not necessary. For pulp capping, use calcium hydroxide. Apply GC Cavity Conditioner (10 seconds) or GC Dentin Conditioner (20 seconds) to the bonding surfaces using a cotton pellet or sponge (Fig. 2). Follow the respective instructions for use. Rinse thoroughly with water and dry the tooth by blotting with a cotton pellet or gently blowing with an air syringe. Do not desiccate the tooth. Optimal results occur when the prepared surfaces appear moist and glistening (Fig. 3).
Mix the required amount of GC Gold Label IX GP-EXTRA. The working time is 2 minutes from the start of mixing at 23°C (73.4°F). Higher temperatures will reduce working time. Transfer the cement to the preparation using a syringe or other suitable instrument, avoiding air bubbles. Shape the preliminary contour and cover with a matrix if needed (Fig. 4). When set, immediately apply GC Fuji Varnish (blow dry) or GC Fuji Coat LC (light cure for 10 seconds).
4. Finishing
Begin final finishing under water spray using standard techniques, 6 minutes after the start of mixing. Apply a final coat of G-Coat Plus and light cure for 20 seconds (Fig. 5, 6). Alternatively, apply GC Fuji Varnish (blow dry) or GC Fuji Coat LC (light cure for 10 seconds). Instruct the patient to avoid applying pressure for 1 hour.
