What Every Dentist Should Know About Mechanical Retention - Bonding & Beer Ep. 44

In Episode 44, Rolando Nuñez takes a closer look at one of the most fundamental (and often overlooked) principles of adhesive dentistry: mechanical retention. With today's advanced adhesives and primers, it's easy to focus entirely on chemistry. But even the best bonding systems depend on proper surface preparation to achieve predictable, long-lasting results. In this episode, we discuss why mechanical retention still matters, how it impacts bond strength, and the critical role it plays when bonding to today's most common restorative materials.

In this episode we discuss:
• What mechanical retention is and why it matters
• How hydrofluoric acid etching and sandblasting create retention
• Common mistakes that can weaken restorations
• How to properly prepare the top 4 dental substrates for optimal bonding
