Filtek Bulk Fill Posterior Restorative is a light-cure, universal composite engineered for one-step posterior restorations up to 5 mm depth. It combines TRUE nanofiller technology with two innovative methacrylate monomers—AFM (addition-fragmentation monomer) and AUDMA—to reduce polymerization stress while maintaining strength and esthetics. Key Features & Benefits: One-step placement up to 5 mm — eliminates the need for incremental layering or capping layers. Low-shrinkage, low-stress chemistry — AFM and AUDMA monomers shrink less and relieve stress during polymerization. Excellent handling and sculptability — packs well and adapts easily without expensive dispensing tools. High wear resistance and strength — flexural and compressive strength are competitive with leading bulk fill and universal composites. Superior polish and esthetics — TRUE nanofillers deliver luster and polish retention. Proven clinical performance — in simulated operator trials, placement time was 24% faster than incremental composites and preferred by twice the number of dentists.
