Why Deep Composite Restorations Fail: Shrinkage, Curing & Microleakage - Bonding & Beer - Ep. 51
Notas del episodio
Composite shrinkage is unavoidable, but improper curing in deep restorations can increase the risk of poor bonding, gap formation, and microleakage.
In this episode of Bonding and Beer, Rolando breaks down the Low Shrinkage Technique and explains why light-curing distance matters, how curing intensity can vary, and why a composite that feels hard may not necessarily be fully polymerized.
We discuss how dual-cured adhesives and restorative materials can help reduce dependence on light activation in deep areas of the preparation, along with practical ways to improve curing predictability and help minimize microleakage.
In this episode, we discuss:
• Composite polymerization shrinkage
• Microleakage and secondary caries
• Light-curing distance and intensity
• Depth of cure
• Using a radiometer to check curing-light output
• Dual-cure materials in deep restorations
• The Low Shrinkage Technique
