A widely used technique for restoring teeth with impaired tooth structure after endodontic treatment is post and core restorations. Various techniques of fabrication of cast post like modified indirect technique, prosthetically guided technique, cast post fabrication using CAD- CAM along with the conventional techniques have been discussed in this literature. Customised post and core fabrication using computerised technology is a quick and easy substitute for traditional techniques. After doing a literature search, a summary of publications covering the fabrication processes and materials utilised to create post and cores using both traditional methods and CAD/CAM have been supplied. There have been reports of both direct and indirect ways for using CAD/CAM post and cores to restore teeth that have undergone endodontic treatment. The materials that were reported the most frequently were zirconia and hybrid ceramic. There are few published data on CAD/CAM post and core; however additional research is required to see how this treatment will perform over the long run.
