In endodontics, the access to the root canal is essential for the treatment success. Pulp canal obliteration (PCO) is a challenge for conventional endodontic treatments with a high risk of fracture of endodontic instruments.Currently, guided endodontic treatments, or digitally guided accesses, are novel alternatives with multiple benefits for the treatment of PCO. The objective of this case report is to describe the protocol for static guided access in PCO, indicating the advantages and considerations of the treatment. A case report of four patients treated between July 2021 and June 2022 is presented. These patients required endodontic treatments in anterior teeth with PCO. In order to virtually plan the direction and length of the access, using a software, we used a cone Beam Computed Tomography (CBCT) and an intraoral scan. Then, a 3D printing of the static guide was made, which directs the entry of the drill. With this method, it was possible to find the root canal in one session and perform the endodontic treatment successfully and conservatively. In conclusion, although static guided endodontics requires planification, it allows a safe endodontic treatment in patients with PCO.
