Determining the Optimum Material for an Endodontic Prefabricated Parallel Post Using a Sub-Problem Approximation Method

Abstract:

One of the most widely used techniques in present-day in order to save teeth is endodontic treatment (ET). Nowadays, a post or a dowel is widely used in the tooth treatment process. The aims of the current investigation are to: (1) evaluate the stress distribution surrounding the endodontic prefabricated parallel post (EPPP), gutta-percha, and dentin with six types of post materials, and (2) determine the optimum material of an EPPP. Six post materials: (1) carbon fibre post (CFP), (2) gold (G), (3) gold alloy (GA), (4) titanium (T), (5) titanium alloy (TA), and (6) stainless steel (SS) were selected in the present work. In order to evaluate the stress distribution surrounding the EPPP, gutta-percha, and dentin with different post materials, the finite element analysis (FEA) is adopted. After that, the sub-problem approximation method was used in order to investigate the optimum material of an EPPP. The results obtained indicate that the optimum elastic characteristics for the EPPP, elastic modulus (E), and Poisson’s ratio (υ) equal to 185 GPa and 0.245, respectively.
