Five years of restorative resin-based composite advancements: a narrative review

Resin-based composites (RBCs) have been utilized for over 50 years, and their application continues to grow. This widespread use necessitates higher standards regarding their characteristics and performance. Despite manufacturers' efforts to introduce optimal versions of RBC materials, the rapid production of new resin composites has not always been matched by corresponding research into their clinical effectiveness. This review discusses the latest technological advancements in restorative RBC materials over the past five years and ongoing research efforts aimed at enhancing restoration durability. The review is organized into themes, including modifications in the resin matrix, modifications in fillers, and modifications in coupling agents of resin-based composite materials. Within the specified timeframe, this review highlights several noteworthy research advances that demonstrate significant improvements in the properties of RBC materials. Although many of these developments are still in the early stages of research, their potential future applications appear promising.
