Preparation and Pretreatment
Etching and priming are essential steps to ensure proper adhesion. Moisture control is critical, often requiring a rubber dam to prevent contamination during the procedure.
Etching and Priming
Etching and priming are critical steps for ensuring proper adhesion. Use a phosphoric acid etchant to prepare the restoration surface, followed by rinsing and drying. Apply the primer according to the instructions to create a strong bond between the restoration and cement. Proper surface preparation enhances the cement’s performance and longevity, ensuring a reliable and durable restoration.
Moisture Control
Moisture control is essential for optimal bonding; Use a rubber dam to isolate the area and prevent contamination. Ensure the restoration surface is dry before applying the cement. Excess moisture can compromise adhesion, leading to reduced bond strength and potential failure. Proper isolation ensures a clean, dry environment, maximizing the cement’s self-adhesive properties and promoting long-term durability of the restoration.
Application Steps
Dispense RelyX Unicem 2 using the Automix syringe, ensuring even coverage. Fill the crown or restoration with 0.5-1mm of cement. Seat with gentle pressure for optimal bonding. Dual-cure technology simplifies the process, eliminating the need for additional curing steps, while ensuring a strong, durable bond.
Filling the Crown
Filling the crown with RelyX Unicem 2 involves dispensing a thin, even layer of cement, typically 0.5-1mm, across the restoration surface. Use the Automix syringe for precise application, ensuring complete coverage without excess. Proper filling ensures a strong bond and prevents contamination. Maintain gentle pressure during seating to achieve optimal results and avoid air bubbles.
- Apply 0.5-1mm layer for ideal bonding.
- Avoid overfilling to prevent cleanup challenges.
- Ensure even distribution for a durable seal.
Using the Automix Syringe
The Automix syringe simplifies precise cement application with its dual-cure technology. Shake vigorously before use and dispense a small amount onto a mixing pad. Use the syringe tip to apply directly to the restoration surface or tooth. Ensure continuous flow for uniform mixing, preventing air bubbles. This method ensures efficient, mess-free application, enhancing clinical outcomes and saving time during procedures.
Indications and Usage
RelyX Unicem 2 is ideal for luting ceramic, composite, and metal-based restorations, including crowns, bridges, inlays, onlays, and veneers. Suitable for anterior and posterior teeth.
Ceramic and Composite Restorations
RelyX Unicem 2 is highly effective for bonding ceramic and composite restorations, ensuring a strong, durable connection. Its self-adhesive properties simplify the process, eliminating the need for additional priming or bonding agents. Ideal for materials like IPS e.max and Celtra Duo, it provides excellent adhesion and reduces post-operative sensitivity. The cement’s dual-cure technology ensures long-lasting stability, making it a reliable choice for both anterior and posterior ceramic and composite restorations.
Metal-Based Restorations
RelyX Unicem 2 excels in cementing metal-based restorations, offering strong adhesion without the need for additional primers. Its self-adhesive formula ensures a reliable bond to metal surfaces, while the dual-cure mechanism enhances durability. Suitable for crowns, bridges, and implants, it provides excellent marginal sealing and resistance to dislocation. This makes it a versatile and efficient choice for metal-based restorations, ensuring long-term clinical success and patient satisfaction.
Post-Cementation Care
Avoid contamination by ensuring the cemented area is clean and dry. Follow proper polishing techniques to remove excess material and achieve a smooth surface finish.
Avoiding Contamination
To prevent contamination, ensure the treated area is dry and free from saliva, blood, or other contaminants. Use a rubber dam or suction to maintain a clean field. Avoid touching the cement or restoration surfaces with bare hands or unsterilized instruments. Properly handle and store the cement to prevent exposure to moisture or light, which can compromise its properties. Follow the manufacturer’s instructions for handling and application to ensure optimal results.
Final Polishing
After cementation, allow the material to fully set before polishing. Use progressively finer polishing burs to remove excess cement and smooth the margins. Start with coarse grit burs for shaping and transition to fine polishing wheels for a high-luster finish. Ensure all surfaces are polished to prevent plaque accumulation and ensure optimal patient comfort. Proper polishing enhances the restoration’s aesthetics and longevity, maintaining a natural appearance and function.
Troubleshooting Common Issues
Common issues include adhesion failures due to improper surface preparation and excess cement requiring careful removal. Contamination during handling can compromise bond strength and longevity.
Dealing with Adhesion Failures
Adhesion failures with RelyX Unicem 2 often result from improper surface preparation or contamination. Ensure surfaces are clean, dry, and properly etched. Re-etch and re-prime if necessary, following instructions precisely. Avoid using oil-based products, as they can interfere with bonding; Re-cementation may be required, but only after thorough surface re-preparation to ensure optimal adhesion and long-term stability of the restoration.
Excess Cement Removal
Excess RelyX Unicem 2 should be removed carefully to avoid damaging the restoration or surrounding tissues. Use a sharp dental explorer or scaler to gently lift excess material while the cement is still fresh. Avoid using harsh abrasives, as they may scratch the restoration. Polish the area smoothly to ensure a seamless finish and maintain the integrity of the cement bond, ensuring both functionality and aesthetics are preserved.
