Mandible as, Inferior View

Description

Viewed from below, the mandible presents a U-shaped body with a smoothly curving inferior border extending between the right and left angles (anguli mandibulae). Posteriorly, each ramus ascends from the angle toward the condylar process and coronoid process, separated by the mandibular notch, with the condylar heads positioned posterolateral to the symphyseal region. Along the inferior aspect of the body, the digastric fossae lie near the midline on the lingual surface, while the gonial regions broaden laterally at the junction of body and ramus. Orientation is unambiguous. An inferior perspective clarifies landmarks used in maxillofacial trauma assessment, where angle and body fractures can be correlated with occlusal disturbance and step deformity along the lower border. Surgeons also reference this contour during submandibular approaches and during open reduction and internal fixation, because plate placement tracks the inferior border while avoiding injury to the marginal mandibular branch of the facial nerve as it crosses near the mandibular margin anterior to the angle. For temporomandibular joint discussions, the position of the condylar processes relative to the rami helps frame condylar neck fracture patterns and dislocation mechanics. Suitable for head and neck anatomy teaching, dental and oral surgery course materials, and radiology correlation pages that pair a 3D bony model with mandibular series views (submentovertex and panoramic concepts). It also fits operative manuals covering mandibular angle fixation, genioplasty planning, and implant or reconstruction plate contouring references.
