Forames mentuais anômalos: Relato de caso e considerações anatômicas

The mental foramen is an important anatomical structure, usually present as through a single (bilateral) opening in the vestibular portion of the mandible, located adjacent to the apex of the lower premolars. Anatomical variations occur, such as accessory mental foramina, which must be carefully evaluated during preoperative planning to avoid damage to their emergent neurovascular bundles. The present study describes the detection/presence of bilateral accessory mental foramen in the mandible via cone beam computed tomography prior to dental implant surgery.
