A correct bonding protocol is the foundation of every successful direct composite restoration. The quality of your bonding protocol plays a significant role in both the strength and longevity of the restoration. Universal adhesives like GC G-Premio Bond simplify the bonding protocol without compromising performance. This guide covers how to optimise your bonding protocol for direct composites, ensuring predictable results, minimal sensitivity, and long-term success.
Etching Techniques in Bonding Protocol
Understanding the three etching modes is fundamental to selecting the right bonding protocol for each clinical situation.
- Total Etch — Enamel (10–15 sec) & dentin (15 sec) etched with phosphoric acid
- Selective Etch — Only enamel phosphoric acid etch (10–15 sec)
- Self Etch — No phosphoric acid on enamel or dentin; adhesive does the work
Dentin Management in Your Bonding Protocol
- Dry Dentin ⚠️ — Collapsed collagen fibres, poor bonding infiltration, post-op sensitivity & hydrolysis
- Hydrated Dentin ✅ — Expanded collagen fibres, proper bonding infiltration, stronger durable bond
Key Takeaway: Always maintain dentin in a hydrated state before adhesive application to prevent collagen collapse and ensure optimal bonding infiltration.
The Smear Layer & Bonding Protocol
To increase bonding infiltration, one must handle the smear layer (debris) caused during cavity preparation:
- Total etch bonding protocol: Phosphoric acid removes the smear layer completely
- Selective etch bonding protocol: The adhesive modifies and infiltrates the smear layer simultaneously
- Air abrasion: Can also modify the smear layer before adhesive application
