Background: The present study describes the surgical conduct in a case of ameloblastoma planned with the use of rapid prototyping based on biomodels simulating the tumor in the patient.
Case Report: A 43-year-old black male patient had oral-maxillofacial trauma and surgery, with a 3-year complaint of a large increase in facial volume, lower lip paresthesia, and pain. The diagnosis of ameloblastoma was obtained through an incisional biopsy of the tumor on the alveolar ridge in the region posterior to the retromolar trigone. Surgery was planned based on tomograms used to generate a biomodel of the patient. Surgery was simulated on the stereolithographic model for the subsequent complete resection of the tumor with margins of safety, without maintaining the base of the mandible and with the placement of the reconstruction plate of the 2.4-mm system. The patient is currently in follow-up and awaiting bone reconstruction surgery due to the biological behavior of the tumor.
Conclusions: Biomodels constitute an excellent tool to assist in the diagnosis, surgical planning, and follow-up of patients.
