GC Gold Label 9 / Fuji IX (Powder-Liquid) Restorative GIC - Regular Pack A2

GC Gold Label 9 / Fuji IX (Powder-Liquid) Restorative GIC in shade A2 is a high-strength, strontium-based glass ionomer cement designed for a variety of dental restorative applications. This true glass ionomer material chemically bonds to tooth structure and is formulated to release fluoride, contributing to internal remineralization and enhancing surface strength over time.

This restorative GIC is indicated for Class I and small Class II restorations in non-load bearing areas, Class I and Class II restorations in deciduous teeth, transitional restorations, and base/core build-ups in both permanent and deciduous teeth. It is also suitable for Class V and root surface restorations. The material is optimized for posterior restorations, offering enhanced durability and wear resistance.

The powder-liquid formulation allows for a hand-mix preparation, providing a working time of 2 minutes from the start of mixing at 23°C (73.4°F). It exhibits a net setting time of 2 minutes 20 seconds at 23°C (73.4°F), enabling efficient clinical workflows. Final finishing can commence approximately 6 minutes after the start of mixing.

Key Features : 

Strontium-based glass ionomer cement for permanent and temporary restorations, including Class I, small Class II, Class V, root surface, transitional, and base/core build-ups.
Hand-mix powder-liquid system with a working time of 2 minutes at 23°C (73.4°F) for controlled application.
Fast net setting time of 2 minutes 20 seconds at 23°C (73.4°F), allowing for timely completion of procedures.
Exhibits no shrinkage during chemical setting and thermal expansion matching natural teeth, reducing stress on the marginal seal.
Formulated with strontium glass for superior radiopacity and high compressive strength of 268 MPa.
Offers wear resistance 60% higher than conventional glass ionomers, ensuring long-lasting restorations.

1. POWDER AND LIQUID DISPENSING

The standard powder-to-liquid ratio is 3.4g/ 1.0g. (1 level scoop of powder to 1 drop of liquid).
For accurate dispensing of powder, lightly tap the bottle against the hand. Do not shake or invert.
To dispense the correct amount of liquid from the bottle turn the bottle upside down, keep 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.
Close bottles tightly immediately after use.
2. MIXING

Dispense powder and liquid onto the pad. Using the plastic spatula, divide the powder into 2 equal parts. Mix the first portion with all the liquid for 10 seconds. Incorporate the remaining portion and mix the whole thoroughly for 15-20 seconds (Fig. 1).
3. RESTORATIVE TECHNIQUE

Prepare the tooth using standard techniques. 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).
Refer to the respective instructions for use.
Rinse thoroughly with water. Dry by blotting with a cotton pellet or gently blowing with an air syringe. DO NOT DESICCATE. The best results are obtained when prepared surfaces appear moist (glistening) (Fig. 3).
Mix the required amount of GC Gold Label IX GP-EXTRA. Working time is 2 minutes from the start of mixing at 23°C (73.4°F). Higher temperatures will shorten working time.
Transfer cement to the preparation using a syringe or other suitable instrument. Avoid air bubbles.
From the preliminary contour and cover with a matrix if required (Fig. 4). g) When set, immediately apply GC Fuji VARNISH (blow dry) or GC Fuji COAT LC (light cure for 10 sec.).
4. FINISHING

Final finishing under water spray using standard techniques can begin at 6 minutes after starting the mix.
Apply a final coat of G-COAT PLUS and light cure for 20 sec. (Fig.5, 6). Alternatively, apply GC Fuji VARNISH (blow dry) or GC Fuji COAT LC (light cure for 10 sec.)
Instruct the patient not to apply pressure for 1 hour.
