case presentation feature by Jason Olitsky, DMD Introduction Trend Toward Better Bulk Fill Composites Traditionally, the procedure for placing large direct posterior restorations has been complex and problematic. In order to guarantee success of the restoration, dentists had to meticulously place composite material by layering and curing 2mm increments.1 The marginal leakage and polymerization shrinkage commonly associated with resin composites were causing clinical failures. In order to address these challenges, flowable composite material was introduced. This new material enhanced marginal adaption and reduced micro-leakage,2 although an additional “capping” layer of composite was needed to create suitable anatomical form. A growing demand from dentists and patients emerged for an advanced bulk fill material that would be simpler to place and provide the required strength and aesthetics. As a result, bulk fill materials demonstrating an improved depth of cure, greater shrinkage resistance and incorporating shrinkage stress relievers were developed. Today’s bulk fill composites demonstrate marginal integrity, adequate resistance to chewing forces in the posterior region, ample working time in ambient light, sufficient radiopacity, good polishing properties, sculptability and aesthetics.3 As a result, modern bulk-fill composites enable dentists to place restorations more efficiently and confidently. 1. 2. 3. 84 Wieczkowski G Jr, Joynt RB, Klockowski R, Davis EL.
