Mechanical and thermal stress evaluation of PEEK prefabricated post with different head design in endodontically treated tooth: 3D-finite element analysis

نویسندگان

چکیده

An endodontic post is required to retain and support the core restoration in case of insufficient remaining coronal dentin after root canal therapy. This study analyzed biomechanical thermal behavior PEEK prefabricated choosing head design that produces least amount stress on tooth structure. These results were compared with most common commercially available post, which titanium glass fiber post. Thus a CBCT scanning maxillary central incisor its supporting structure was used construct 3D solid model an endodontically treated teeth for finite element analysis (FEA). The restored spherical yielded more benign distribution repairable failure mode crown, luting cement, core, under both mechanical loads, followed by respectively.
