Özet
With the advent of new provisional crown materials, it has become imperative to evaluate their strength in order to select the appropriate crown material. This study examined the fracture resistance of three different provisional materials. To simulate oral conditions, the specimens were fabricated in brass molds, ensuring their similarity to premolars. The 33 fabricated specimens were divided into three groups (n=11) and stored at 37°C in artificial saliva (1.6 g NaHCO3, 0.4 g NaH2PO4H2O, and 0.1 g CaCl2H2O per L H2O). After conditioning, the fracture resistance was assessed using a universal testing machine (Testometric). Analysis of variance and Student's t-test were used for statistical analysis. The study concluded that the mechanical properties of provisional restorative materials are strongly influenced by their proportions of methyl methacrylate and bisphenol A glycidyl methacrylate.
