Stress Distribution Surrounding Endodontic Prefabricated Parallel Post

Abstract:

The identification of the optimum material of an endodontic prefabricated parallel post (EPPP) is carried out in the current study. The primary goal of the current work is to analyze the effect of post material on the stress distribution surrounding EPPP. Ten different post materials: 1-carbon fibre (CF), 2-gold alloy (GA), 3-titanium alloy (TA), 4-stainless steel (SS), 5-composite resin (CR), 6-fiber reinforced composite (FRFC), 7-carbon (C), 8-glass fiber (GF), 9-zirconia (Z), and 10-ribbond fiber+bonding agent+flowable composite (RBF) are used in the present work. In order to identify the best post material, the stress distribution surrounding EPPP with the previous materials are investigated through finite element analysis (FEA). The results obtained show that, the best material of an EPPP is GF. In this study, in order to identify the optimum material of an EPPP, the optimization technique is adopted. The results obtained show that, the optimum values of elastic modulus (E) and Poisson’s ratio (υ) equal to 63.69 GPa and 0.214115, respectively. These resulting values mean that, the optimum material of an EPPP is borosillicate glass (BG).
