New dimethacrylate monomer Bis-EFMA was synthesized and used to prepare Bis-GMA-free dental resin and composite materials. Studies of the experimental materials showed that Bis-EFMA-based resin matrix and composite materials had improved properties compared to Bis-GMA-based resin matrix and composite materials, respectively. Compared with the commercial dental composite material Z250, Bis-EFMA-based composite showed similar or improved properties except for a lower FS after water immersion. Based on the presented results, Bis-EFMA has potential to be used in commercial dental composites.
