Course Description:

This online course qualifies for 1.5 CE hours. 

For assured success in composite fillings, the tooth bond to composite interface must be sealed – no gap. Therefore, polymerization shrinkage is the enemy in bulkfill composites when bacteria is allowed to get in the resulting gaps. The high shrinking stress tends to break the bond to the tooth, leading to a gap or white line (fracture) when on enamel. Fortunately, there is a breakthrough development that helps dentists close the gap due to polymerization shrinkage.

Presented by internationally renowned lecturer, Dr. Raymond L. Bertolotti, DDS, PhD, this exciting course reviews the latest clinical research that’s proving to be a game changer in composites. Through lecture, images, and video examples, you’ll learn how to “close the gap” between composite fillings and teeth for more successful and effective dentistry. 

Course Objectives:

  • Learn why bulkfill composites don’t make sense.
  • Discover a new polymerization chemistry that effectively pulls the composite toward the bond and closes any gaps.
  • How to avoid post-op bite pressure sensitivity and recurrent caries.
  • Compare microleakage at the cervical margin for multiple products.
  • Recognize and eliminate the white line or microfracture of the enamel due to polymerization stress.
  • Review laboratory tests on leakage affecting the critical gingival margin on a Class II composite.
