A digital technique for a prefabricated custom post-and-core restoration

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. Threedimensional 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. (J Prosthet Dent 2023;130:278-83)

Automated summary

This technique utilizes cone beam computed tomography (CBCT) and CAD-CAM software to achieve prefabricated and custom restoration of endodontically treated teeth. Three-dimensional preparation guides are used to ensure proper fit, saving time and reducing risk.
