Some applications, little explored today, have to do with the use of 3D-printed devices for the localization of hard-to-reach lesions. To determine the position of mandibular bone lesions, we propose using 3D printed localization guides manufactured \"in-house,\" using freely licensed design programs (software) to design them, and made of biocompatible resins.

With the help of customized cutting guides, intraoperative placement is precise. These are created utilizing a fused filament manufacturing 3D printer and polylactic acid.
