Excess cement can be removed with a brush or explorer. Light curing may be necessary for dual-cure cases‚ following the Instructions for Use for optimal results and a secure bond.
Curing the Cement
RelyX Unicem cures through a dual-curing mechanism‚ combining chemical and light activation. Use a light curing unit at 450-480 nm for 15-20 seconds to ensure proper polymerization and final set.
5.1 Light Curing Techniques
Hold the light curing unit at a distance of 2-10 mm and perpendicular to the restoration surface. Cure for 15 seconds using a light with a wavelength of 450-480 nm. Ensure the light tip is clean and free of debris for optimal energy transmission. Avoid moving the light during curing to maintain consistent polymerization. This step finalizes the cement’s set and ensures a durable bond.
5.2 Post-Curing Care
Avoid using high-pressure water or instruments to remove excess cement. Gently rinse with oil-free air and inspect the margins. Remove any excess cement using a hand instrument or floss. Ensure the occlusion is checked and adjusted if necessary. Final polishing can be done with rubber wheels or polishing pastes to achieve a smooth surface. This step ensures patient comfort and restores natural aesthetics.
Post-Cementation Care
Ensure the restoration is fully seated and excess cement is removed. Check occlusion and adjust if necessary. Final polishing enhances aesthetics and patient comfort‚ completing the procedure.
6.1 Final Polishing and Adjustments
After cementation‚ final polishing is essential to smooth rough edges and refine the restoration’s surface. Use polishing burs or wheels to achieve a high luster‚ ensuring patient comfort and aesthetics. Adjustments should be made to correct any occlusal discrepancies‚ ensuring proper bite alignment and functionality. This step finalizes the restoration‚ enhancing both durability and patient satisfaction.
6.2 Patient Instructions for Post-Care
Patients should avoid chewing hard or sticky foods for 24 hours post-cementation. Good oral hygiene practices‚ including regular brushing and flossing‚ are essential.
