ABSTRACT
This technique provides a prefabricated and custom post-and-core to restore endodontically treated teeth to be delivered at the preparation appointment. Cone beam computed tomography (CBCT) is used to extract the post shape from a root canal, and a computer-aided design and computer-aided manufacturing (CAD-CAM) software program is used to design the core. The post and the core are combined and milled before post space preparation. Three-dimensional preparation guides are fabricated and used in post space preparation to ensure that the prefabricated and custom post-and-core fits after the preparation. This technique can save time and reduce the risk of perforation while preparing the root canal.
