A standardized mesio-occlusal-distal cavity was prepared with cervical margins 1 mm above the cementoenamel junction and oral and buccal walls with 1.5-mm remaining thickness. Universal adhesive was used in all specimens in etch-and-rinse mode. Specimens were divided into four groups (n = 15 each) according to restoration technique: CSM group, adhesive overlay with hybrid ceramic (CeraSmart, GC); EXP group, direct composite restoration (Essentia U, GC) and everX Posterior (GC) as core material; ESU group, direct composite restoration (Essentia U); and EST group, direct composite restoration (Essentia U) reinforced with horizontal bidirectional glass fibers placed over the pulpal chamber floor (everStick-Net, GC). After 7 days of water storage, samples were loaded until fracture using a universal testing machine. The maximum breaking loads were recorded in Newtons (N), and statistical analysis was then conducted with two-way analysis of variance and post hoc Tukey test. Fragments were analyzed using scanning electron microscopy.\n Results: Mean fracture resistance was: CSM = 1,428.9 \u00b1 316.90 N; EXP = 1,874.57 \u00b1 299.47; ESU = 1,557.44 \u00b1 355.65; and EST = 1,870.27 \u00b1 145.11. CSM and EXP showed the highest strength values when compared to the other groups. The variable &#8220;fiber insertion&#8221; did not significantly alter the fracture resistance. Origins of the fractures were always located on the occlusal surface, mainly from the major contact loading area.\n Conclusion: The use of everX Posterior showed great improvement in fracture resistance, similar to cuspal coverage restoration. However, only short fiber-reinforced composite resins showed a favorable fracture pattern.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Authors MICHELOTTO TEMPESTA Riccardo, SARATTI Carlo
