“…The results of mechanical properties are presented in Table . For the methacrylate silane, the smallest filler YBF402 (0.05 μm) had the lowest values of flexural strength, as expected . For thiourethane silane, the highest values were obtained with composites filled with YGB700.…”

Thiourethane oligomers added to methacrylate matrices improve fracture toughness and reduce polymerization stress. In this study, the oligomers are added to the surface of inorganic fillers in the formulation of resin composites. Systematically varied fillers treated either with the thiourethane or a methacrylate silane control are tested. Thiourethane reduces the rate of polymerization of light‐cured composites but does not affect the final degree of conversion. Filler functionalization with thiourethane increases the depth of polymerization, in filler type‐dependent fashion. Thiourethane reduces the polymerization stress for all fillers. The findings suggest that this approach results in the same general effects with the addition of thiourethanes directly to the matrix. This is accomplished with a lower overall concentration of thiourethane, and with no prejudice to the handling characteristics of the material. © 2019 Wiley Periodicals, Inc. J. Appl. Polym.

“…The most common classification system for composites considers the distribution and average filler particle size . Based on the classification systems by Lutz and Phillips in 1983, composites can be classified into: macrofilled, microfilled, hybrids, modern hybrids, and nanofilled composites.…”

“…Compared to the limited range of shades of the early macrofilled and microfilled composites, modern hybrid composites (0.5–1.0 μm and 10–50 nm) are ideal for esthetic restorations of anterior teeth, because of a variety of different shades with tailored opacity and translucency . Furthermore, with the rise of nanotechnology, nanofilled composites came into being with inorganic phases of characteristic dimensions in the range of 10–100 nm . Because of the increased filler loading and reduced amount of resin matrix, nanofilled composites thereby reduced the polymerization shrinkage while providing esthetics and strength …”

With filler particle sizes ranging from about 10 to 50 μm, conventional or macrofilled composites were mechanically strong, but difficult to polish and to retain a favorable color match.…”

Dental composites are comprised of a polymerizable matrix and reinforcing fillers that can be hardened into a solid restoration in the prepared tooth cavity. Composites are becoming increasingly popular due to their esthetics and improved mechanical and physical properties. However, dental composites still encounter several problems, mainly secondary (recurrent) caries, restoration fracture, excessive wear, marginal degradation, and tooth sensitivity. Therefore, extensive efforts are underway to improve the composite compositions and microstructure, and enhance their clinical performance and longevity. Relying on advances in materials science and technology, dental composites have been continuously improved and their clinical applications have been expanded. In this review article, the development of dental composites was summarized, including compositional changes, performance improvements in key areas, current research hot spots, and outlook for future direction. The intention is to provide a review of the history and development of dental composites with a discussion of strategies on addressing the current challenges facing dental composites. In addition, this review will provide a better understanding of dental composites and their properties for the practicing clinicians, to contribute to improving the quality of composite restorations. The review of literature indicates that while current composites are generally bio‐inert and can replace the missing tooth structure, future composites should be bioactive and therapeutic to inhibit caries, modulate biofilms, and protect the surrounding tooth structures, in order to increase the restoration longevity. © 2019 Wiley Periodicals, Inc.

Synopsis After a brief review of current restorative materials and classifications, this article discusses the latest developments in polymer-based direct filling materials, with emphasis on products and studies available in the last 10 years. This will include the more recent bulk-fill composites and self-adhesive materials, for which clinical evidence of success, albeit somewhat limited, is already available. The article will also introduce the latest cutting edge research topics on new materials for composite restorations, and an outlook for the future of how those may help improve the service-life of dental composite restorations.
