Elevating the Humble Direct Posterior Composite


Seminar Schedule:

Seminar start: 10:00 am
Duration: 2 hours

It's just a filling...This is a common phrase used to describe posterior Class II direct composites. Rather than devalue this ubiquitous service, our profession should elevate it as a foundational practice. When delivered with care, these restorations have the potential for longevity in function and beauty, delaying the need for more reductive restorative solutions. Hybridizing a Biomimetic Restorative core for dentin replacement along with an injection overmolded enamel replacement combines the best of two restorative disciplines for superior outcomes.

Learning Objectives:

  • Introduction to Biomimetic Restorative Principles for stronger dentin adhesion.
  • Introduction to Structural Analysis and basics for crack dissection.
  • Matrix options and assembly for quadrant strategy.
  • Learning the steps for Injection Overmolding.
  • Learn the simple steps for predictable high gloss polish.
