Abstract

Abstract: Resin-based dental composites are promising tooth-resembling materials in restorative dentistry. The limited longevity of dental composite restorations due to the bulk/marginal fracture and secondary caries as well as possible health risks are the critical challenges faced by such materials. Therefore, developments of resin-based dental composites received considerable attention in academic researches for clinical applications. A comprehensive review of the recent developments in the scientific literature on resin-based dental composites is presented in this article. Firstly, in the article, the challenges in dental composites are introduced and then the chemical aspects of the systems are classified through a review of employed resins. Subsequently, the different characteristics related to the fillers employed for the development of the resin-based dental composites are described. Finally, conclusions are drawn and future insights are proposed. This article provides an insight that paves the way for tailoring and designing resin-based dental composites for clinical applications. Graphical abstract: The chemistry of monomers and various aspects of the filler phase in dental composites are reviewed. Image 1 Highlights: Overview of strategies to overcome dental composites' shortcomings is provided. Dental monomers based on characteristic functional moieties are classified. Effect of factors in filler phase design on dental composite properties is reported. Future insights on dental composites from the material point of view are presented.
