Mandibular Fracture (Broken Lower Jaw)

TMJ After An AccidentInformation About Fractures to the Lower Jaw

Mandibular fractures, also known as lower jaw fractures, are quite common due to the location of the mandible bone and the lack of support for the mandible. These fractures are common among men between 21 to 30 years old. A lower jaw fracture is the most common facial fracture after nasal fractures. Mandible fractures are usually caused by a direct blow to the lower jaw like when the head snaps forward and strikes the steering wheel during a car accident. Most people that sustain a fractured mandible bone experience bleeding in their mouth and a feeling that their teeth are not aligned properly.

Associated Injuries

Patients with mandible fractures sometimes also suffer from head injuries, head and neck lacerations, maxillary fractures, eye injuries, nasal fractures, tooth fracture, facial lacerations, Temporomandibular Joint (TMJ) Disorder, and cervical spine injuries.


Mandible fractures fall into one of the following categories:

  • Simple/closed: The fracture does not feature an open wound
  • Compound/open: External wound involving skin, periodontal membrane, or mucosa
  • Comminuted: The bone is crushed or splintered
  • Complicated/complex: Where there is injury to adjacent soft tissues or parts
  • Atrophic: Characterized by severe atrophy of the bone
  • Multiple: Two or more lines of fracture on the same bone not communicating with each other
  • Greenstick: One cortex of the bone is broken; the other is bent
  • Pathologic: Preexisting bone disease has caused fracture occurring from mild injury
  • Impacted: One fragment is driven firmly into the other
  • Indirect: Fracture is distant from the injury site

Condylar Fractures

The most common fractured site is in the condylar region, with five levels of severity:

  • Fracture of the neck of the condyle with slight displacement of the head; angle between the head and axis of the ramus is between 10 and 45 degrees.
  • Produce an angle ranging from 45 to 90 degrees, resulting in tearing of the medial portion of the joint capsule.
  • Fragments are not in contact, but confined within the glenoid fossa; the head is displaced medially and forward; the capsule is torn and the head is out of it.
  • Of the head articular on or in a forward position in terms of the articular eminence.
  • Vertical or oblique fractures through the head of the condyle.
