Summary
Properly preparing porcelain surfaces is key for strong bonding of indirect restorations like veneers. This review clarifies various surface treatments, including acids and silane coupling agents, to improve dental adhesive effectiveness.
Area of Science:
- Dental Materials Science
- Restorative Dentistry
Background:
- Indirect restorations (porcelain veneers, inlays, onlays) require surface treatment for optimal bonding.
- Current literature presents conflicting information on the efficacy of various porcelain surface preparation techniques.
Purpose of the Study:
- To clarify and make sense of diverse methodologies for treating porcelain intaglio surfaces before cementation.
- To provide guidance on effective surface preparation for dental restorations.
Main Methods:
- Review of advocated surface preparation techniques for porcelain.
- Analysis of methods including acid etching, particle abrasion, adhesives, and silane coupling agents.
Main Results:
- The effectiveness of different porcelain surface treatments varies.
- Understanding these techniques is crucial for predictable bonding outcomes.
Conclusions:
- A clear understanding of porcelain surface treatments is essential for successful indirect restoration placement.
- Further research may be needed to definitively establish the superiority of specific preparation methods.
