The human mandible, also known as the lower jaw, is anatomically complex and it is the only movable bone in the facial area facilitating the functions of mastication, speech and facial expressions. It also serves as a scaffold and platform for the lower dentition, muscle insertions, temporomandibular joint, nerves, and vessels. Important mandibular structures are the two mandibular canals that are located bilaterally underneath the teeth in the premolar and molar regions. The mandibular canals have two openings called mandibular foramen in the ramus area, and mental foramen in the parasymphyseal area. Each canal contains the artery and vein as well as the inferior alveolar nerve, which is part of the mandibular branch of the trigeminus nerve that supplies the motor innervations to muscles and sensory innervations to the teeth, chin, and lower lip.
