Abstract
Statement of problem. Earlier research has not determined which post material favors best stress dispersal inside the post-core restoration and role of partial ferrule in longitivity of crown prosthesis.Purpose. The goal of this research was to establish which post material produces the best stress distribution under loading and to evaluate role of partial or complete ferrule in stress distribution within tooth and associated structures.
Material and methods. 3D models of mandibular second premolar were created with the micro CT scan , further meshing with HYPERMESH program to simulate materials used for tooth and associated structure (gold alloy post, glass fiber post) and metal ceramic crowns. The occlusal surface was loaded with 200 N, and von Mises equivalent stress values were determined with the aid of ANSYS 18.1.
