3M RelyX Ceramic Primer 2721

Clinical Overview

3M™ RelyX™ Ceramic Primer is a prehydrolyzed, silane-based coupling agent designed to enhance the bond between dental adhesives and indirect restorative surfaces. Specifically formulated for porcelain, ceramic, pre-cured composite, and metal substrates, it creates a reliable chemical link that improves adhesion strength and long-term restoration durability.

Key Benefits

• Enhanced bond strength: Improves adhesion between resin cements/adhesives and ceramic or metal surfaces.
• Silane-based chemistry: Promotes chemical coupling for durable and stable bonding.
• Versatile substrate compatibility: Effective on porcelain, ceramics, pre-cured composites, and metals.
• Improved restoration longevity: Reduces risk of debonding in indirect restorations.
• Simple application: Single-step application integrates بسهولة into adhesive protocols.
• Chairside repair ready: Ideal for intraoral repair of fractured ceramic restorations.

Kit Contents

• 1 × 5 mL bottle of 3M™ RelyX™ Ceramic Primer

Working & Setting Times

• Working: Apply to treated surface and allow to react for approximately 60 seconds.
• Setting: Air-dry gently; no light curing required prior to adhesive application.

Indications

• Bonding of ceramic and porcelain restorations
• Preparation of surfaces for resin cementation
• Repair of fractured porcelain, ceramic, or composite restorations
• Enhancing adhesion to pre-cured composite and metal surfaces
• Use prior to adhesive systems in indirect restorative procedures

Instructions for Use

1. Clean and prepare the restoration surface (etch if required).
2. Apply a thin layer of ceramic primer using a brush or applicator.
3. Allow the primer to react for approximately 60 seconds.
4. Gently air-dry to evaporate the solvent.
5. Apply adhesive system according to manufacturer instructions.
6. Proceed with cementation or restorative procedure.

Summary
