Definition: Mandibular fractures can occur singularly or as two fractures creating three segments of the mandible (this is referred to as a segmental fracture). For a refresher on the 4 radiographic features of fractures take a look at the trauma to teeth and jaws page.
Radiographic Features:
Location: Most commonly occurs at the angle of the mandible, neck of the ramus and anterior mandible. Fractures can be continuous with the periodontal ligament space of a tooth as they continue superiorly.
Edge: Well-defined.
Shape: Can be linear or jagged. May not have a definitive shape.
Internal: Radiolucent when seen as a line, but can also be radiopaque when seen as two segments overlapping each other.
Other: None.
Number: May be single or multiple.
