DEFINITION AND CLINICAL FEATURES Ameloblastoma is a benign tumor arising from the odontogenic epithelium and is more commonly seen in the mandible compared to the maxilla (Figure 1.3). They are most commonly associated with unerupted teeth and are generally seen in the posterior aspect of the maxilla or mandible. These tumors are rarely malignant or metastatic; however, they are progressively enlarging lesions that can be locally destructive to the native bone and surrounding soft tissue. Accordingly, they can cause significant facial deformity and functional difficulties with mastication if left untreated.
