Scientific advancements in bulk fill composite materials.

Bulk fill composite materials were first introduced over 15 years ago to help improve the efficiency of direct posterior restorations.

The traditional layering technique of composite materials for direct posterior restorations is time consuming. And, the longer you work in the mouth the greater the risk of contamination from blood or saliva, which can compromise the final clinical outcome. 

Bulk fill composite materials were designed to eliminate the layering technique required for traditional dental restorations in favour of an easy, single-step “bulk fill.” It sounds great in theory, but many dentists are still hesitant to try bulk filling materials due to concerns surrounding polymerization stress, ability to light cure, and the overall esthetic results.

So, we went back to the drawing board to come up with an advanced bulk fill composite material for direct posterior restorations.

Here’s what you need to know about 3M™ Filtek™ One Bulk Fill Restorative.

The technology behind 3M’s advanced bulk fill composite material.

  • Improved esthetics and excellent depth of cure with Smart Contrast Ratio Management technology: 3M™ Filtek™ One Bulk Fill Restorative is equipped with 3M’s nanofiller technology for superior wear resistance and excellent polish retention. The nanoparticles are chemically synthesized allowing for more control over the physical and optical properties of the filler. The Smart Contrast Ratio Management technology allows for deeper light penetration into the composite with increased opacity for improved esthetics.1
  • Control of polymerization stress with innovative AUDMA and AFM monomers: The utilization of addition-fragmentation monomer (AFM) and aromatic urethane dimethacrylate (AUDMA) in 3M™ Filtek™ One Bulk Fill Restorative resin system has helped make the bulk-filling process easier for dentists. Together, these monomers help to reduce shrinkage and relieve stress – to allow bulk fill placement up to 5 mm (for a Class II).2
