A broken jaw (or mandible fracture) is a common facial injury. Only the nose is broken more frequently. A broken jaw is the 10th most common fractured bone in the human body. Fractures (breaks in the bone) are generally the result of a direct force or trauma to the jawbone (mandible). A dislocated jawbone means that the temporomandibular joint (where the jaw connects with the skull) is moved out of place.
The skull can be divided into two main parts: the cranium and the mandible. The cranium is the largest part of the skull enclosing the brain, eyes, ears and nose. The mandible is the lower jaw, also known as the jaw bone. A human adult skull is made of 22 bones: 8 cranial bones and 14 facial bones. Except for the mandible, where the bones meet are ragged edges called sutures.
