The success rate of endodontic microsurgery (EM) can be reduced for several reasons, including the tooth's position in the mouth. For this reason, using 3-dimensional (3D) computer-aided design/computer-aided manufacturing (CAD/CAM) guides has become common. Despite their great advantages, these guides have some limitations, including the difficulty of taking impressions and scanning in shallow vestibules. In this case report, we propose a design of an anatomical guide for endodontic microsurgery with a cortical bone window tailored for optimal accuracy from the patient's tomography, digital segmentation, and 3D printing.
