ObjectivesTo distinguish the physical properties of a new silorane-based restorative material in comparison to five methacrylate-based restorative materials – a compomer, giomer, nanocomposite, hybrid and micro-hybrid.MethodsThe following properties were examined per restorative material: compressive strength, diametral tensile strength, flexural strength/modulus, fracture toughness, microhardness, and polymerization shrinkage. The mean and standard deviation were determined per group. A one-way ANOVA/Tukey was performed per property (α = 0.05).ResultsSignificant differences were found between groups per property (p < 0.001).ConclusionsCompared to the methacrylate-based restorative materials, the new silorane-based material had the lowest polymerization shrinkage, but an overall mixed mechanical performance. The silorane-based material had relatively higher flexural strength/modulus, fracture toughness, but relatively lower compressive strength and microhardness than the methacrylate-based restorative materials.
