Impact of a Core Ferrule Design on Fracture Resistance of Teeth Restored with Cast Post and Core
Objectives. To investigate the influence of a contra bevel on the fracture resistance of teeth restored with cast post and core. Materials and Methods. Sixty plastic analogues of an upper incisor were endodontically treated and prepared with 6° internal taper and 2 mm of ferrule in order to receive a cast post and core. The prepared samples were divided into two groups (n = 30); the first group...
متن کاملevaluation of retention of two different cast post-core systems and fracture resistance of the restored teeth
statement of the problem: the survival of pulpless teeth restored with different post and core systems is still a controversial issue. purpose: this study compared the retention of two different post and core systems and also the fracture resistance of teeth restored with these systems. material and method: eighty endodontically treated maxillary central incisors were sectioned perpendicular to...
متن کاملa finite element study of teeth restored with post and core: effect of design, material, and ferrule
background: different postdesigns and materials are available; however, no consensus exists regarding superiority for stress distribution. the aim of this study was to evaluate the effect of design and material of post with or without ferrule on stress distribution using finite element analysis. materials and methods: a total of 12 three‑dimensional (3d) axisymmetric models of postretained cent...

متن کاملComparison of the Fracture Resistance of Endodontically Treated Maxillary Incisors Restored with Six Different Post and Core Systems
Background and Aim: Different methods and materials are available for post and core (P&C) fabrication. We aimed to compare the fracture resistance and failure modes of endodontically treated maxillary central incisors restored with six different P&C systems. Materials and Methods: In this in-vitro study, after endodontic treatment and coronal preparation of 60 maxillary central incisors, six d...
