USE OF DIGITAL WORKFLOW FOR FABRICATION OF MILLED TITANIUM INTRARADICULAR POSTS

Abstract

With advancements in dental technology, it is possible to mill materials such as fiberglass and titanium to achieve long-term clinical performance in intracanal post systems. Milling is performed using a CAD/CAM system, a technology that performs design (CAD) and computer-aided manufacturing (CAM), and can be used in both laboratory and clinical settings. Teeth that have undergone endodontic treatment often require an intracanal post due to biomechanical failures resulting from tooth structure loss. Therefore, the material used is also crucial to ensure the post's survival, with a modulus of elasticity similar to that of dentin. This study aimed to describe the digital workflow for fabricating a post and core, using pure titanium as the chosen material due to its biocompatibility with the dentin structure. In this case, the patient presented with a fracture in the composite resin on the buccal, mesial, distal, and occlusal surfaces of tooth 24, with satisfactory root canal treatment. Since the patient's complaint was purely functional, a titanium post and core was recommended, achieving a satisfactory result. The method saved time, demonstrating the efficiency of the workflow compared to the conventional technique. This technique made it possible to visualize the post and core in 3D in relation to the canal, providing greater predictability, longevity, and function to the treatment.
