Summary
The resin-ceramic bond strength is crucial for durable resin-bonded CAD/CAM ceramic restorations. This article updates best practices for ceramic bonding protocols, including surface pretreatment and priming agents for common CAD/CAM ceramics.
Area of Science:
- Dental Materials Science
- Biomaterials Engineering
Background:
- Resin-bonded CAD/CAM ceramic restorations are increasingly popular.
- Restoration longevity and clinical quality depend on resin-ceramic bond strength and durability.
- Selecting appropriate ceramic bonding protocols is vital due to diverse ceramic materials and compositions.
Purpose of the Study:
- To provide a comprehensive update on current resin-bonding protocols for commonly used CAD/CAM ceramics.
- To highlight the importance of ceramic type and composition in protocol selection.
Main Methods:
- Review of current literature on resin-bonding protocols for CAD/CAM ceramics.
- Analysis of typical protocol steps: surface pretreatment and priming agent application.
Main Results:
- The choice of bonding protocol is significantly influenced by ceramic material type and composition.
- Standard protocols involve specific surface pretreatment and priming agent application steps.
Conclusions:
- Adherence to optimized bonding protocols is essential for predictable clinical outcomes.
- Understanding ceramic properties is key to selecting effective bonding strategies for CAD/CAM restorations.
