Background: Following endodontic treatment, it is crucial to utilize a suitable restorative technique to secure the coronal seal as well as shield remaining dental structure. When two or more walls of a tooth are lost, it becomes necessary to restore it with posts in order to enhance retention and stability of the final restoration. These posts can be categorized as either prefabricated or customized, and can be produced via the CAD-CAM. Purpose: The development of digital dentistry has been aimed at augmenting the accuracy of workflow and expediting the production process. The focus of this case report is the restoration of undamaged teeth that have undergone endodontic treatment. This was done with the assistance of a CAD-CAM post and core system that was milled through digital impression. Patients and Methods: For this particular case, the method employed involved utilizing an intraoral scan for the fabrication of a post and core restoration for inferior premolars that had undergone endodontic treatment. This approach was derived from in vitro experiments which validated the intraoral scanner's capacity to accurately discern post-space up to a depth of 12 mm with the assistance of the scan post. Results: The digital technique allows us to convert the concave surface of the root canal into the convex surface of the post, and realize an anatomical post and core that improves the biomechanics of the endodontically treated tooth reducing the possibility of root fractures. Conclusion: The use of an intraoral digital scanner represents an opportunity for the clinician as it speeds up the production of an anatomical post and core restorations.
