When restoring an endodontically treated tooth with deficient coronal tooth structure, posts can be used to strengthen the tooth. Recently prefabricated posts are widely used as they exclude the need for complex laboratory procedures making the procedure time saving. But the post-placement can produce stresses that cause root fracture. Different techniques can be used to study the stress distribution due to different posts, but most of them are two-dimensional and difficult to reproduce.
