A post-and-cores are dental restorations used to sufficiently build up tooth structure for future restoration with a crown, when there is not enough tooth structure for proper retaining, due to loss of tooth structure from decay or fracture. Posts are cemented into canals to enhance retention and to aid in creating a seal along the canal.There are many different post-and-core systems, prefabricated and custom made, but none can provide perfect restorative solution for every clinical case.Digital dentistry (CAD-CAM) is widely present in the laboratory and dental offices. It is precise, fast and simple technology which can be used for fabricating of post and cores also. An optical scanner collects images of three-dimensional structures utilizing triangulation procedure. The traditional silicon impression is scanned to mill a personalized post or a scanner penetrateinto the canal depth and read it down. Different methods have been presented during last years, and appropriate techniques for digitalizing should be determined.Keywords:post-and-core, CAD-CAM, zirconia post, fiber post
