GC Gold Label Hybrid Restorative GIC - A2

GC Gold Label Hybrid Restorative GIC in shade A2 is a self-adhesive, hand-mixed glass ionomer cement featuring advanced Glass Hybrid technology. This restorative material is designed for a wide range of dental applications, including Class I and Class II restorations in primary (deciduous) teeth, non-load bearing Class I and Class II restorations, intermediate restorations, and base material for high-stress Class I and Class II cavities using the sandwich laminate technique. It is also suitable for Class V and root surface restorations, as well as core build-up procedures. The material is radiopaque, ensuring clear visibility under dental radiographs for precise placement and evaluation.

The advanced Glass Hybrid technology integrates two types of Fluoro-Alumino-Silicate (FAS) glass with two types of polyacrylic acid, resulting in superior mechanical strength and durability. Finer FAS glass particles enhance translucency by reducing light reflection, allowing more light to pass through the restorative material for a natural appearance. Additionally, the formulation promotes high fluoride release, contributing to tooth remineralization and decay prevention. The inclusion of acid-resistant FAS glass and a high molecular weight polyacrylic acid further strengthens the restorative matrix, improving its resistance to acid and enhancing long-term durability.

For clinical application, the GC Gold Label Hybrid requires a powder to liquid ratio of 3.0 g / 1.0 g, with a mixing time of 25-30 seconds to achieve a smooth, homogenous consistency. The working time at 23°C (73°F) is 1 minute 45 seconds from the start of mixing, allowing for efficient manipulation and placement. The net setting time at 37°C (99°F) is 2 minutes 40 seconds, and final finishing under water spray can commence 6 minutes after the initiation of mixing.

INSTRUCTIONS FOR USE

1. Powder and Liquid Dispensing

Recommended ratio: 3.0 g powder to 1.0 g liquid (1 level scoop of powder to 1 drop of liquid).

Dispensing powder: Lightly tap the bottle against your hand for accurate dispensing. Do not shake or invert the bottle.

Dispensing liquid: Hold the liquid bottle vertically and squeeze gently.

After dispensing: Immediately close the bottles tightly to prevent contamination or evaporation.

2. Cavity Preparation

Tooth preparation: Prepare the tooth using standard clinical techniques. Extensive mechanical retention is not required. For pulp capping, use calcium hydroxide.

Conditioning (optional): Apply cavity conditioner or dentin conditioner to the bonding surfaces if indicated.

Rinse and moisture control: Thoroughly rinse with water. Remove excess moisture with a cotton pellet or gentle air stream. Do not desiccate the tooth. The prepared surface should appear moist and glistening.

3. Mixing Procedure

Dispense the required powder and liquid onto a mixing pad.

Using a plastic spatula, divide the powder into two equal portions.

Mix the first portion of powder with all the liquid for 10 seconds.

Add the remaining powder portion and mix thoroughly for an additional 15 to 20 seconds until a homogeneous consistency is achieved.

4. Restorative Technique

Working time is approximately 1 minute 45 seconds from the start of mixing at 23°C (73°F). Higher temperatures will shorten the working time.

Transfer the cement into the prepared cavity using a suitable instrument, avoiding air bubbles.

Establish preliminary contour and place a matrix if required.

Once set, immediately apply GC Fuji Varnish (air dry) or G-Coat PLUS (light cure).

5. Finishing Procedure

Begin final finishing under water spray approximately 6 minutes after the start of mixing.

Apply a final coat of GC Fuji Varnish or G-Coat PLUS.

Advise the patient not to apply pressure to the restoration for 1 hour.
