RelyX Cement is a dual-cure adhesive resin cement designed for bonding ceramic, composite, and metal restorations, offering excellent bond strength and versatility in dental applications.
1.1 Overview of RelyX Cement
RelyX Cement is a versatile, dual-cure adhesive resin cement designed for bonding various restorations, including crowns, bridges, veneers, and endodontic posts. It offers excellent bond strength, aesthetics, and ease of use, making it suitable for ceramic, composite, and metal restorations. Its unique formulation ensures durability and compatibility with different dental materials, catering to a wide range of clinical needs.
1.2 Key Features and Benefits
RelyX Cement offers dual-curing technology, combining light activation with self-curing properties for reliable setting. It provides strong adhesion to tooth structure and restorative materials, minimizing marginal gaps. The cement ensures high aesthetics, ideal for anterior and posterior restorations. Its self-adhesive formula simplifies application, eliminating the need for separate bonding agents, while maintaining excellent durability and clinical performance over time.
Preparing the Tooth and Surface
Remove temporary restorations and clean the tooth surface thoroughly. Ensure the area is free from debris and oils to optimize bonding and cement adhesion.
2.1 Removing Temporary Restorations
Start by carefully removing any temporary restorations to ensure a clean working surface. Use appropriate tools to gently pry or dissolve temporary cements, taking care not to damage the underlying tooth structure. Once removed, thoroughly clean the area with a non-oil-containing abrasive paste and rinse to eliminate any residual material.
2.2 Cleaning and Preparing the Tooth Surface
Clean the tooth surface thoroughly using a non-oil-containing abrasive paste to remove temporary cement residues. Rinse with water and dry completely to ensure a contamination-free surface. Etch the tooth with phosphoric acid for 15 seconds to create microretention, then rinse and dry again. This step ensures optimal bonding between the tooth and RelyX Cement.
2.3 Surface Treatments (Etching, Sandblasting, Silanization)
Etch the tooth surface with phosphoric acid for 15 seconds to create microretention. Sandblast restorations with aluminum oxide to enhance surface roughness. For ceramic surfaces, apply silane to improve bonding. These treatments ensure optimal adhesion, promoting a strong and durable bond between the tooth and RelyX Cement, enhancing the longevity of the restoration;
Mixing RelyX Cement
Mix RelyX Cement in a 1:1 powder-to-liquid ratio for 30 seconds until homogeneous. Avoid contamination and use immediately for optimal bonding and setting properties.
3.1 Dispensing the Cement
Dispense RelyX Cement onto a mixing pad using 1-2 clicks for single-tooth restorations. Ensure the surface is dry to prevent contamination. Avoid excess to maintain control during application. Proper dispensing ensures the right amount for bonding, preventing waste and ensuring even mixing. This step is crucial for achieving optimal results in the cementation process.
3.2 Mixing Ratios and Techniques
Mix RelyX Cement using a 1:1 scoop-to-drop ratio. Dispense powder and liquid on a mixing pad, then combine thoroughly for 30 seconds. Ensure a homogeneous mix to achieve optimal consistency and bonding performance. Avoid over-mixing to prevent air bubbles, which can compromise the cement’s strength and longevity. Proper mixing is essential for successful restoration bonding.
Applying RelyX Cement
Dispense RelyX Cement onto a mixing pad, then apply to the restoration or tooth surface. Use 1-2 clicks for a single tooth restoration, ensuring even coverage.
4.1 Dispensing onto the Mixing Pad
Dispense RelyX Cement onto a clean, dry mixing pad using the Clicker dispenser. Typically, 1-2 clicks are sufficient for a single tooth restoration. Avoid excess to prevent waste and ensure precise application.
4.2 Applying to the Restoration or Tooth
Apply RelyX Cement to the restoration or tooth surface using a brush or applicator. Ensure thin, even layers for optimal bonding. Gently press the restoration onto the tooth, allowing excess cement to spread naturally. Avoid overloading to prevent contamination and ensure proper adaptation. The dual-cure mechanism ensures reliable bonding once applied correctly.
Curing the Cement
RelyX Cement uses a dual-cure mechanism, combining light curing (10 seconds per surface at 1200 mW/cm²) and self-curing for reliable bonding and stability over time.
5.1 Dual-Curing Mechanism (Light and Self-Cure)
RelyX Cement features a dual-curing mechanism, combining light activation and self-curing processes. Light curing initiates polymerization quickly, while the self-curing component ensures continued setting over time, enhancing bond strength and stability.
5.2 Recommended Curing Times and Methods
For optimal results, cure RelyX Cement with a light curing unit at 1200 mW/cm² for 10 seconds per surface. Alternatively, allow 6 minutes for self-curing. Follow manufacturer guidelines for specific curing times to ensure proper polymerization and durability of the restoration.
Post-Cementation Care
RelyX Cement cures via dual mechanisms: light curing at 1200 mW/cm² for 10 seconds per surface or self-curing in 6 minutes. Follow guidelines for optimal polymerization and durability.
6.1 Finishing and Polishing
After cementation, use a pumice paste without oil to gently remove excess material. Rinse thoroughly with water, ensuring no residue remains. Avoid contamination during finishing to maintain bond integrity and aesthetics of the restoration.
6.2 Checking the Margins and Occlusion
After cementation, inspect the margins with a dental explorer to ensure a smooth, well-sealed interface. Check occlusion to prevent excessive forces on the restoration. Adjustments should be made carefully to avoid damage. Proper margination and occlusal alignment are critical for the long-term success and functionality of the restoration.
Specific Techniques for Different Restorations
RelyX Cement offers tailored techniques for diverse restorations, including crowns, bridges, veneers, and endodontic posts, ensuring optimal adaptation and bond strength for each dental application.
7.1 Crowns and Bridges
RelyX Cement is ideal for cementing crowns and bridges, providing a strong, durable bond. Ensure proper surface preparation, including etching and cleaning. Apply a thin layer of cement to the restoration, seat it gently, and cure using the dual-cure mechanism. Light cure for 10 seconds per surface or allow self-cure for optimal results, ensuring marginal integrity and long-term stability.
7.2 Veneers and Onlays
For veneers and onlays, ensure proper surface preparation by etching and silanizing. Apply a thin layer of RelyX Cement to the restoration, seating it gently. Use the dual-cure mechanism, light curing for 10 seconds per surface or allowing self-cure. This ensures a strong bond and aesthetic results, ideal for thin restorations requiring precision and durability.
7.4 Endodontic Posts and Implant Restorations
For endodontic posts and implant restorations, clean the post with alcohol and air dry. Apply silane according to the manufacturer’s instructions. Dispense RelyX Cement in a 1:1 ratio, mix for 30 seconds, and apply evenly. Ensure proper seating to avoid air bubbles. The dual-cure mechanism ensures reliable bonding, while the strong bond strength supports long-term durability for these critical restorations.
Troubleshooting Common Issues
Contamination can prevent proper bonding, while excess cement may require immediate removal. Follow instructions carefully to avoid these issues and ensure optimal results with RelyX Cement.
8.1 Avoiding Contamination
To prevent contamination, ensure all surfaces are clean and dry before applying RelyX Cement. Avoid exposing the cement to moisture or saliva, as this may compromise adhesion. Use gloves and work in a controlled environment to minimize contamination risks, ensuring a successful bonding process for your dental restorations.
8.2 Managing Excess Cement
Excess RelyX Cement can be gently removed using a scalpel or explorer before it fully sets. Avoid using water, as it may interfere with curing. After curing, any remaining excess can be polished away with fine-grit burs and polishing discs to ensure a smooth finish and proper occlusion, maintaining the restoration’s integrity and aesthetics.
Adhering to RelyX Cement instructions ensures optimal bonding and durability, making it a reliable choice for various dental restorations when used with proper techniques and precautions.
9.1 Summary of Key Steps
