Mechanical Properties of Ceramics and Composite Resins

We investigated the mechanical properties of certain dental restorative materials to assess their durability. This study determines the flexural strength of a ceramic material (Finesse, Dentsply), a hybrid ceramic resin (Estenia, Kuraray), an ormocer (Admiral, Voco) and a posterior composite resin (...

Description
Summary:We investigated the mechanical properties of certain dental restorative materials to assess their durability. This study determines the flexural strength of a ceramic material (Finesse, Dentsply), a hybrid ceramic resin (Estenia, Kuraray), an ormocer (Admiral, Voco) and a posterior composite resin (Solitaire2, Heraeus Kulzer). The specimens were fabricated from the various restoratives. Flexural strength was determined in 4-point bending. Scanning electron microscopy (SEM) was used to examine and compare surface topography of the fractured and non-fractured surfaces. The results were analyzed statistically. The flexural strength values of Estenia samples were significantly higher compared to those of Admiral and Finesse (p < 0.006).
