Preparation for Cementation

Preparation involves sandblasting with 30-50 micron aluminum oxide at 2 Bar and cleaning with alcohol to ensure a proper surface for cementation.

3.1 Preparing the Restoration

Preparing the restoration involves several key steps to ensure proper bonding and fit. First‚ sandblast the surfaces to be cemented with 30-50 micron aluminum oxide at 2 Bar pressure to create a matte finish. This step enhances surface roughness‚ improving adhesion. Next‚ clean the restoration thoroughly with alcohol to remove any contaminants. For glass ceramics‚ check the fit and contact points before cementation to avoid adjustments post-cementation; Ensure all surfaces are dry and free from debris. Proper preparation is critical for the self-adhesive properties of RelyX Unicem 2 to function effectively. Following these steps ensures a strong‚ durable bond between the restoration and the tooth structure.

3.2 Pretreating the Tooth

Pretreating the tooth is a critical step to ensure optimal bonding with RelyX Unicem 2. Begin by cleaning the tooth surface with pumice and water to remove plaque‚ bacteria‚ and stains. Rinse thoroughly and dry the area to create a clean‚ dry environment for cementation. For glass ceramic restorations‚ avoid occlusal adjustments before cementation to prevent damage. Ensure the tooth is free of contaminants‚ as the self-adhesive properties of RelyX Unicem 2 rely on direct contact with the tooth structure. No etching or bonding agents are required‚ simplifying the process. Proper tooth preparation enhances the cement’s adhesion and ensures a durable‚ long-lasting bond. Always follow the manufacturer’s guidelines for specific pretreatment requirements based on the type of restoration being used.

3.3 Cleaning and Sandblasting

Cleaning and sandblasting are essential steps to prepare the restoration and tooth surface for cementation with RelyX Unicem 2. Sandblast the surfaces to be cemented using 30 or 50 micron aluminum oxide at a pressure of 2 Bar (30 psi). This creates a matte surface appearance‚ enhancing the bond between the cement and the restoration. After sandblasting‚ clean the area with alcohol to remove any residue or contaminants. Proper cleaning ensures a strong and durable bond. For glass ceramics‚ avoid sandblasting or use a gentler method to prevent damage. Always follow the manufacturer’s recommendations for specific materials to ensure compatibility and optimal results. Clean surfaces are critical for the self-adhesive properties of RelyX Unicem 2 to function effectively‚ ensuring a successful and long-lasting cementation.

Cementation Technique

RelyX Unicem 2 is applied directly to the prepared restoration or tooth surface. Use the automix syringe for precise delivery‚ ensuring even coverage. Seat the restoration gently‚ removing excess cement. Follow proper curing techniques for a secure bond.

4.1 Applying the Cement

Applying RelyX Unicem 2 begins with preparing the restoration and tooth surface. Use the automix syringe to dispense the cement evenly‚ ensuring precise delivery. Apply a thin‚ uniform layer to the restoration or tooth surface‚ avoiding excess. Proper application ensures optimal adhesion and minimizes cleanup. Always follow the Instructions for Use (IFU) for detailed guidance. The self-adhesive properties eliminate the need for etching or bonding agents‚ streamlining the process. After applying‚ proceed to seat the restoration carefully to avoid air bubbles. Excess cement can be removed with a suitable instrument. The cement’s dual-curing properties ensure a strong‚ durable bond. Proper technique is critical for successful outcomes.

4.2 Seating the Restoration

Seating the restoration with RelyX Unicem 2 requires precision to ensure proper fit and alignment. Gently place the restoration onto the prepared tooth‚ aligning it correctly to avoid misplacement. Apply gentle‚ consistent pressure to seat the restoration fully‚ ensuring complete contact with the tooth surface. Excess cement that extrudes from the margins should be removed immediately using a suitable dental instrument. Proper seating is critical to prevent voids or air bubbles‚ which could compromise the bond. The self-adhesive and dual-curing properties of RelyX Unicem 2 promote a strong‚ durable bond without the need for additional etching or bonding steps. Always follow the Instructions for Use (IFU) for optimal results and to ensure the longevity of the restoration.

4.3 Final Curing Process

The final curing process for RelyX Unicem 2 involves both chemical and light curing to ensure a strong‚ durable bond. After seating the restoration‚ use a curing light with a wavelength of 450-490 nm and an intensity of at least 600 mW/cm². Cure for 20 seconds per surface‚ ensuring complete coverage. The dual-curing mechanism allows the cement to set quickly‚ even in areas not reached by the light. Proper curing is essential for achieving optimal mechanical properties and bond strength. Once cured‚ excess material can be removed‚ and the restoration can be finished and polished. Always follow the recommended curing times and techniques outlined in the Instructions for Use (IFU) to ensure the best results.

Post-Cementation Care

After cementation‚ ensure proper finishing and polishing to achieve a smooth surface. Provide patients with post-operative instructions to maintain oral hygiene and avoid excessive force on restorations.

5.1 Finishing and Polishing

After cementation‚ finishing and polishing are crucial to ensure a smooth‚ natural surface. Begin by removing excess cement with a scalpel or fine-grit sandpaper. Use progressively finer polishing burs to achieve a high luster. Avoid using coarse abrasives that may damage the restoration or surrounding tooth structure. Clean the area with water and inspect for any remaining cement or rough edges. Final polishing with a rubber polishing wheel and fluoride-containing paste enhances the surface finish and prevents plaque accumulation. Proper finishing and polishing not only improve aesthetics but also reduce the risk of irritation or inflammation. Always follow the manufacturer’s guidelines for specific polishing techniques tailored to the type of restoration material used.

5.2 Post-Operative Instructions

After cementation‚ patients should avoid chewing hard or sticky foods for 24 hours to allow the cement to fully set. Good oral hygiene practices‚ such as brushing and flossing‚ should be maintained to prevent plaque buildup around the restoration. Patients should avoid using abrasive toothpaste or mouthwashes containing alcohol‚ as these may degrade the cement. It is important to schedule a follow-up appointment to ensure the restoration is functioning properly and to address any concerns. Patients should also be advised to attend regular dental check-ups for long-term monitoring. Proper post-operative care ensures the longevity and success of the restoration‚ maintaining both function and aesthetics.

Troubleshooting Common Issues

Common issues include incomplete curing‚ contamination‚ or improper mixing. Ensure correct mixing techniques‚ avoid moisture contamination‚ and verify adequate curing time for optimal results.

6.1 Common Problems and Solutions

Troubleshooting with RelyX Unicem 2 often involves addressing issues like incomplete curing or contamination. To resolve these‚ ensure proper mixing techniques and avoid moisture exposure during application. If the cement does not flow correctly‚ check the automix syringe for blockages. For incomplete curing‚ verify that the curing light is functioning properly and that the cement is exposed to the correct wavelength and duration. Contamination can be prevented by using clean‚ dry instruments and surfaces. If bonding fails‚ ensure the restoration and tooth surfaces are properly prepared‚ including sandblasting for better adhesion. Following the Instructions for Use (IFU) carefully can help minimize these issues and ensure successful outcomes.

6.2 Tips for Avoiding Errors
