Large variations between the tested materials within a material category were found. Data were analyzed with the one-way analysis of variance (ANOVA) followed by the Tukey& amp #39 s test and partial eta-squared statistics (p & amp lt 0.05). The fracture toughness (K(IC)) of 69 restorative materials belonging to ten materials categories-micro-hybrid, nanofilled, microfilled, packable, ormocer-based, and flowable resin-based composites (RBC), compomers and flowable compomers, as well as glass ionomer cements (GIC) and resin-modified GIC was measured by means of the single-edge notched-beam method after storing the samples (n = 8) for 24 h in distilled water. Therefore, the study aims to analyse the fracture toughness of a large number of dental restorative materials categories. The ability of a restorative material to withstand fracture is of crucial importance especially in stress-bearing area. For small cavities, alternative technologies could be preferred as the need for mechanical resistance is lower and the potential for stress generation is greater. Under high occlusal load, the use of Grandio and V34930 might be favoured. From the present findings, it was suggested that V35694 and Filtek Silorane exhibit comparable properties to conventional methacrylate-based composites, although clinically the cavity type and location must guide material choice. The results were analyzed using anova tests (P 0♰5). Dynamic modulus was determined by an impulse excitation technique, static elastic moduli and flexural strength by a three-point bending method.

Inorganic fillers were quantified by thermogravimetric analysis and morphologically characterized by scanning electron microscopy. Two Ormocers (Admira and an experimental Ormocer V35694), one ring-opening composite (Filtek Silorane) and five methacrylate-based composites were tested.

The aim of this study was to characterize the inorganic fraction of materials belonging to each type and to compare their mechanical properties. Summary Three types of low-shrinkage composites are today commercially available: Ormocers, cationic ring-opening curing systems and highly filled methacrylate-based materials, which cure via free-radical polymerization mechanisms.
