Instructions for Use
Use GC Fuji II LC in premeasured capsules for no-mess mixing. Light cure for 20 seconds, finish, and polish. Apply GC Fuji VARNISH or COAT LC for final sealing.
Mixing and Preparation
GC Fuji II LC is available in premeasured unit dose capsules for convenient, mess-free mixing. Simply use the provided mixing pad and scoop to combine the powder and liquid. The recommended powder-to-liquid ratio is 3.2g/1.0g. Ensure the mixture is homogeneous before application. Avoid adding extra liquid, as this may compromise material properties. Use the capsule’s contents immediately after mixing to maintain optimal consistency. For refills, use the powder and liquid bottles, following the same ratio. Always refer to the instructions for precise measurements and techniques to ensure proper handling and application of the material.
Application Techniques
Apply GC Fuji II LC in thin, uniform increments of up to 1.8 mm to ensure proper curing. Use a suitable dental instrument to shape and adapt the material to the cavity walls. Light cure each increment for 20 seconds. For restorations, start with a base or liner, followed by subsequent layers. Ensure each layer is fully cured before adding the next. The material can also be used in a sandwich technique, combining it with composite resins for complex restorations. Proper adaptation and contouring are crucial for optimal results. Finish and polish the restoration after the final layer is cured, following standard dental polishing procedures for glass ionomer restoratives.
Curing Process
Light cure each increment of GC Fuji II LC for 20 seconds using a compatible light-curing unit. Ensure the light tip is close to the material for effective curing. Avoid excessive light exposure to prevent overheating. After curing, allow the material to set before proceeding with additional layers or finishing. The material achieves initial set quickly, allowing for immediate finishing and polishing. Follow the manufacturer’s guidelines for curing times and intensity to ensure optimal properties. Proper curing is essential for achieving the material’s strength and durability. Always use a radiometer to verify the light output for consistent results. Cure in a way that ensures complete polymerization of each layer for a successful restoration.
Finishing and Polishing
After curing, use polishing burs or stones to shape and smooth the restoration, ensuring proper occlusion and anatomy. Start with coarse grit burs for initial shaping, then progress to finer grits for polishing. Apply a final coat of GC Fuji VARNISH, GC Fuji COAT LC, or G-COAT PLUS, and light cure if required. This step enhances surface smoothness and aesthetics. The material’s tooth-like coefficient of thermal expansion ensures compatibility and durability. Regular polishing maintains the restoration’s appearance and functionality over time. Follow the manufacturer’s recommendations for specific polishing techniques to achieve optimal results. Proper finishing and polishing are critical for patient comfort and the longevity of the restoration.
