Follow the instructions carefully to achieve optimal results and long-lasting durability.
3.1 Mixing and Handling the Cement
To mix RelyX Unicem, insert the capsule into the activator and press the handle completely, holding for 2-4 seconds. The cement is automixed and ready for use immediately. Always handle the cement with gloves to avoid contamination. Dispense the required amount on a clean surface and apply directly to the restoration or tooth preparation. The no-mix, self-adhesive formula ensures ease of use. Work quickly, as the cement begins setting upon exposure to oral moisture. Proper handling prevents air bubbles and ensures a uniform layer for optimal bonding.
3.2 Applying the Cement
Apply RelyX Unicem directly to the prepared tooth or restoration surface. Use a thin, even layer, ensuring complete coverage. For optimal bonding, apply a small amount to both the restoration and tooth surface. Work in a well-lit area to ensure visibility. Gently spread the cement using a clean brush or applicator. Avoid excessive pressure, which can create air bubbles. Work quickly, as the cement begins to set upon contact with moisture. Apply a thin layer to ensure proper seating and fit of the restoration. Immediate seating is recommended to prevent premature setting.
3.3 Seating the Restoration
Seat the restoration with gentle, steady pressure to ensure proper alignment and fit. Use a seating tool or your finger to apply even force, guiding the restoration into place. Avoid excessive pressure, which can displace cement or damage the restoration. Once seated, hold the restoration in place for a few seconds to allow initial bonding. Use a damp cotton pellet or gauze to remove excess cement from the margins. If necessary, use a rubber dam to isolate the area and prevent contamination. Ensure the restoration is fully seated before allowing the cement to set further.
