5.1. Tooth Preparation
Tooth preparation for RelyX Luting Cement involves cleaning the natural tooth structure thoroughly. Remove any temporary cement or debris using non-oil-containing abrasive pastes. This ensures a clean surface for bonding. Gently sandblast the area with 30-50 micron aluminum oxide at 2 Bar pressure to create a matte finish. After sandblasting, rinse with water and dry with oil-free air to prevent contamination. Properly preparing the tooth surface is crucial for achieving a strong and durable bond with the cement. Ensure all surfaces are free from oils, saliva, or other contaminants before proceeding with the cementation process. This step ensures optimal adhesion and long-term success of the restoration.
5.2. Restoration Preparation
Restoration preparation involves ensuring the surface of the prosthesis is ready for cementation. Sandblast the inner surfaces of metal or ceramic restorations with 30-50 micron aluminum oxide at 2 Bar pressure to create a matte finish. This enhances surface roughness for better adhesion. After sandblasting, clean the restoration with ethanol or isopropyl alcohol to remove any contaminants. Use oil-free air to dry the surface thoroughly. For ceramic restorations, avoid using aluminum oxide to prevent damage. Instead, clean with alcohol and ensure the surface is free from any residues. Proper preparation of the restoration ensures optimal bonding with RelyX Luting Cement, promoting a strong and durable connection between the restoration and the tooth structure.
Mixing Instructions
RelyX Luting Cement is mixed in a 1:1 ratio using either manual or Automix systems for precise application and optimal bonding, ensuring efficiency and reliability in dental procedures.
6.1. Manual Mixing
For manual mixing, RelyX Luting Cement is dispensed in a 1:1 ratio using the base and catalyst pastes from the Clicker dispenser. Dispense the required amount onto a mixing pad, ensuring equal portions of both components. Mix thoroughly for 30 seconds using a clean, rigid mixing instrument to achieve a uniform consistency. Avoid introducing air bubbles during mixing. The working time after mixing is approximately 2-3 minutes, depending on environmental conditions. Proper mixing is critical to ensure the cement’s optimal properties, such as bonding strength and setting time.

Cement Placement and Seating
Cement placement and seating are critical steps in achieving a secure and durable bond. Once mixed, the RelyX Luting Cement should be loaded into the restoration, ensuring complete coverage of the internal surfaces. The restoration is then seated gently in the mouth, applying light pressure to ensure proper fit and alignment. Excess cement should be removed immediately with a clean instrument or cotton pellet, working from the margins toward the center. Proper seating ensures minimal excess and prevents occlusal interference. The Automix system allows for precise extrusion, reducing mess and ensuring accurate placement. After seating, the restoration is held in place for a few seconds to prevent shifting. This step ensures the cement flows evenly and adheres properly to both the tooth and restoration surfaces, promoting long-term stability and success of the prosthesis.
Setting and Working Times
The setting and working times of RelyX Luting Cement are designed to provide clinicians with sufficient time for precise placement while ensuring rapid setting. The working time after mixing is approximately 1-2 minutes, allowing ample opportunity to load and seat the restoration. The initial set begins within 2-4 minutes, while the final set is achieved in about 5-6 minutes. These times are optimized for clinical efficiency, enabling quick completion of the procedure without compromising bond strength. The Automix system ensures consistent mixing, maintaining reliable setting times; Clinicians should adhere to these timelines to ensure proper handling and placement, avoiding premature setting or delayed bonding. Proper management of setting times is crucial for achieving a durable and long-lasting bond between the tooth and restoration.
Post-Cementation Care
Proper post-cementation care is essential to ensure the longevity and success of the restoration. After seating the restoration, excess cement should be removed from the margins using a explorer or floss to prevent irritation or caries. The area should be rinsed with water and dried to inspect the margins. Patients should avoid heavy chewing or biting for at least 2 hours to allow the cement to fully set. Polishing can be performed immediately to smooth any rough edges or surfaces. Patients should be advised to maintain good oral hygiene practices, including regular brushing with fluoride toothpaste and dental check-ups; This care ensures the cement’s durability and the restoration’s long-term success.
Troubleshooting Common Issues
Common issues with RelyX Luting Cement may include poor bond strength, contamination, or incorrect mixing ratios. To address these, ensure proper surface preparation and avoid moisture contamination during application. If the mix ratio is off, remix the cement according to the manufacturer’s instructions. For incomplete setting, verify proper working time and environmental conditions. Excess cement around margins can be removed with a explorer or floss. If bonding fails, re-prepare the surfaces and repeat the process. Always follow the instructions for use and handle the material correctly to minimize issues. For persistent problems, consult the troubleshooting section of the official manual or contact technical support for further assistance.
