The Effects of Using Cements of Different Thicknesses and Amalgam Restorations with Different Young’s Modulus Values on Stress on Dental Tissue: An Investigation Using Finite Element Analysis

Background: In this study, it was aimed to use a finite element stress analysis method determine the amount of on enamel, dentin, restoration, resin cement and glass ionomer in amalgam class II disto-occlusal (DO) cavities by using two different cements with thicknesses amalgams Young’ s modulus values, respectively. Methods: A three-dimensional tooth model obtained scanning an extracted human maxillary first molar dental tomography. DO cavity including 95-degree margin angles created. Resin (RC) (GI) measures (RC: 7.7 GPa, GI: 10.8 GPa) were used amalgam. Different thickness combination groups simulated: 50 μm, 100 μm 150 μm. Additionally, values same (Amalgam Young’s modulus: 35 GPa GPa). load 600 N delivered chewing area. The distributions then analyzed analysis. Results: most accumulation observed enamel tissue across all where or restorations values. least itself. Conclusions: According results obtained, there no difference between types terms accumulations models. However, when evaluated, concluded that presence both causes less restoration surface. Furthermore, combined
