Resumo

Ameloblastoma is the most common benign epithelial odontogenic tumor, although it is aggressive and locally invasive, and its treatment frequently results in mandibular defects requiring complex reconstruction. This case report describes a secondary mandibular reconstruction using an iliac crest graft (ICG) assisted by Computed-Aided Design and Computed-Aided Manufacturing (CAD–CAM) technology. A 28-year-old female who was diagnosed with Ameloblastoma in the mandibular region underwent segmental mandibular resection followed by delayed reconstruction planned through virtual surgical planning, mandibular mirroring, and fabrication of patient-specific cutting guides and stereolithographic models. The CAD–CAM workflow enabled accurate graft harvesting and adaptation, and reduced operative time, enhancing surgical predictability and minimizing morbidity. The patient subsequently achieved satisfactory functional and aesthetic rehabilitation and remains under long-term follow-up without recurrence. This report highlights the applicability of CAD–CAM as a reliable and precise strategy for mandibular reconstruction after tumor resection.
