In this episode of Bonding & Beer, we continue our conversation on mechanical retention by shifting our focus from the restoration to the tooth structure itself. We break down why mechanical retention is one of the most important factors in achieving predictable, long-lasting bonds, and why understanding the differences between enamel and dentin can make or break your restorative success. From the history of acid etching to modern techniques like sandblasting and self-etching, we explore how proper surface preparation creates the foundation for optimized bonding.

In this episode, we discuss:
• What mechanical retention really is
• Why mechanical retention is essential for predictable bonding
• The differences between enamel and dentin as bonding substrates
• Creating proper mechanical retention with: phosphoric acid etching, sandblasting, and self-etch techniques
