Directions for Use – Direct Restorations

Step 1: Shade Selection

• Select the appropriate shade prior to isolation

Step 2: Cavity Preparation

• Prepare the cavity according to adhesive technique principles
• Clean with water spray and gently air-dry

Step 3: Pulp Protection

• If required, apply a calcium hydroxide pulp protector (e.g. ApexCal®) only in areas close to the pulp
• Cover with a pressure-resistant liner (e.g. Vivaglass® Liner)

Step 4: Matrix Placement

• Place matrix band and interdental wedge if required

Step 5: Etching

• Apply N-Etch to enamel first and then dentin
• Allow a reaction time of 15 seconds
• Rinse thoroughly with water spray
• Dry with oil-free air, avoiding overdrying of dentin
• Etched enamel should appear chalky white
• If contaminated, repeat etching for a maximum of 10 seconds

Step 6: Application of Tetric N-Bond

• Dispense the required amount into a mixing well
• Apply with a disposable applicator brush
• Protect adhesive from ambient light
• Apply a generous layer to enamel and dentin surfaces

Step 7: Light Curing

• Light-cure Tetric N-Bond according to manufacturer recommendations
• A shiny surface indicates complete coverage
• Polymerize each composite layer individually

Step 8: Finishing and Polishing

• Finish the restoration using suitable finishers or fine diamonds
• Check occlusion
