“…Increasing filler packing to enhance elastic modulus and strength works up to a certain filler level, beyond which there is little additional benefit (Pick et al, 2011;Hahnel et al, 2012) or even a slight decrease in strength (Ikejima et al, 2003). In model composites, an increase in filler size has been shown to increase the elastic modulus (Masouras et al, 2008a), but limited effects on mechanical properties for nanometer-sized (between 7 and 40 nm) particle-based model compositions have been observed .…”

The design of clinical trials allows for limited insights into the fatigue processes occurring in resin composites and the factors involved therein. In vitro studies, in contrast, can fundamentally narrow study interests to focus on particular degradation mechanisms and, to date, represent the major contributors to the state of knowledge on the subject. These studies show that microstructural features are important in determining strength and fracture toughness, whereas fatigue resistance is mainly related to the susceptibility of the matrix and the filler/matrix interface to mechanical and chemical degradation. In this review, we focus on fracture mechanisms occurring during fatigue, on the methods used to assess them, and on additional phenomena involved in the degradation of initial mechanical properties of resin composites.

“…7 The development of a pure-ormocer matrix was an attempt to improve the performance of the admixed ormocers and it has been previous reported as promising. 2,9,12 Consequently, the present study was designed to investigate the influence of the type of organic matrix and filler content on the physical and chemical parameters water sorption and solubility and porosity over the time. Water uptake was influenced by the filler content.…”

“…A pure Ormocer-matrix formulations are believed to offer enhanced clinical performance through high wear resistance, reduced polymerization shrinkage, enhanced biocompatibility, and long-lasting polymer-matrix stability. 8,9 In our previous study the results obtained through a softening test demonstrated that this material formulation was the only material amongst conventional dimethacrylate resin-based and admixed-ormocer that preserved surface integrity after water storage and had the greatest resistance to the ethanol-challenge. 2 Several factors such as formulation, filler content and the amount of porosity influence the water stability of resin-based materials.…”
