Tetric N-Ceram Bulk Fill – Efficient Posterior Restorations

Advanced 4mm Bulk-Fill Composite for Efficient Posterior Restorations

Tetric N-Ceram Bulk Fill by Ivoclar Vivadent is an advanced direct restorative composite for efficient bulk filling of posterior teeth. It features light-curing technology allowing up to 4mm depth of cure, excellent adaptability, and low shrinkage stress for optimal marginal integrity.

Key features:

• Up to 4mm bulk fill capability
• Light-curing range: 400-500 nm (blue light)
• Incorporates Ivocerin light initiator for deep curing
• Low shrinkage and stress for better adaptation
• Three core technologies: new light initiator, stress reliever, and light sensitivity regulator

Advantages over traditional layering:

• Reduces clinical steps and chair time
• Minimizes risk of air bubble incorporation between layers
• Allows for easier, more efficient placement in a single increment

Operating Steps Reference:

1. Apply Eco-Etch: Use the etching gel for 10-15 seconds on enamel and 15-30 seconds on dentin. Rinse thoroughly and dry.
2. Apply Tetric N-Bond Universal: Dispense the adhesive, apply to the prepared surface for 20 seconds, air-dry, then light-cure for 5 seconds.
3. Optional: Apply Tetric N-Flow if needed for specific areas or as a liner.
4. Apply Tetric N-Ceram Bulk Fill: Place the composite in layers up to 4mm thick, adapting it to cavity walls. Light-cure each layer.
5. Light-cure: Use dental curing light unit. Adjust curing time based on light intensity:

• 20 seconds for 500-900 mW/cm²,
• 10 seconds for 900-1,400 mW/cm²,
• 5 seconds for ≥1400mW/cm²
