Resin-Reinforced Glass Ionomer Cement (GC)

Description

Resin-Reinforced Glass Ionomer Cement (RMGIC) by GC combines the benefits of conventional glass ionomer cement with resin technology, giving improved strength, aesthetics, and handling.

🔹 Key Features

• Dual setting mechanism: Acid–base reaction + light/chemical resin polymerization

• Fluoride release & recharge: Helps prevent secondary caries

• Improved strength: Higher flexural and compressive strength than conventional GIC

• Better aesthetics: Smoother surface and improved translucency

• Moisture tolerant: Less sensitive to moisture during placement

• Chemical adhesion: Bonds directly to enamel and dentin without bonding agents

• Reduced solubility compared to conventional GIC

🔹 Indications

• Class III and V restorations

• Cervical erosion/abrasion lesions

• Primary teeth restorations

• Base or liner under composite or amalgam

• Core build-ups (depending on product type)

• Sandwich technique (open/closed)

🔹 Advantages

• Faster setting with light cure option

• Lower post-operative sensitivity

• Thermal expansion similar to tooth structure

• Long-term fluoride protection
