title: Stress analysis of five prefabricated endodontic dowel designs: a photoelastic study.
abstract: The stress generated by five prefabricated endodontic dowel designs was evaluated using a two-dimensional photoelastic model. Cemented posts caused the least stress. Of the threaded posts, Flexi-post and Radix Anker produced the least stress; Kurer Crown Anchor produced the most.
