The mechanical properties of nanofilled resin-based composites: The impact of dry and wet cyclic pre-loading on bi-axial flexure strength

Influence of Storage Condition on Flexure Properties of Nano-Composite

“…In addition, previous work showed that the nano-clusters in nano-filled composite would influence the strength and reliability of the composite, irrespective of the storage and testing condition, which may explain the results of the current work [6,26].…”

“…The improved physical and mechanical properties of RBC, the good esthetics, and the ease of chair side application in addition to acceptable durability of these restorations have led to its high popularity in recent decades. Durability of dental composite restorations is influenced by multiple factors, some are related to materials composition such as resin matrix, filler type and filler loading and others are related to the technique and surrounding environment in which the material is functioning, and recurrent decay could be an additional contributing factor to composite failure [1][2][3][4][5][6][7][8].…”

Factors Involved in Mechanical Fatigue Degradation of Dental Resin Composites

“…This highlights the degradation effects of mechanical stress relative to the amount of the resin phase in resin composites. After challenges of 2,000 cycles at loads from 20 to 100 N, a nanofilled composite (Filtek Supreme) showed better fatigue resistance in comparison with 2 microhybrid composites (Filtek Z250 and Z100) and a nanohybrid (Grandio, Voco, Cuxhaven, Germany) (Curtis et al, 2009), also pointing to an important influence of the microstructure on the fatigue resistance of resin composites. In restored teeth subjected to chewing simulation, the degradation of properties in the bulk of the composite, rather than solely surface microcracking, was shown to govern fatigue performance (Pieniak and Niewczas, 2012).…”

Polymerization shrinkage, flexural and compression properties of low-shrinkage dental resin composites

“…By containing nanofillers, significant increase of filler volume has been achieved with reduction of monomers content and then decrease of polymerization shrinkage. However, compared to many microhybrid composite resins, the filler content of the resin nanocomposites was not dramatically increased, so, questions are arising whether the filler content can further be increased and the increased filler content can further reduce the polymerization shrinkage [20][21][22] . LS is a newly introduced resin composite that includes silorane.…”
