-- The first section of this topic is shown below --



  • Typically due to a direct force
  • The most common area fractured is the angle, followed by the condyle, molar, and mental regions.
  • Because of its thickness, the mandibular symphysis is rarely fractured.
  • Multiple fractures are seen in >50% of cases owing to the ring-like structure of the mandible.
  • Bilateral mandibular fractures most commonly result from motor vehicle accidents (MVAs).
  • Open fractures are common, including lacerations of the gum overlying a fracture.


  • The mandible is the 3rd most common facial fracture following nasal and zygomatic fractures.
  • MVAs, personal violence, contact sports, or industrial accidents
  • Patients are often intoxicated and unable to give a clear history of events.
  • Facial and head lacerations and facial fractures are the most commonly associated injuries.

Pediatric Considerations
  • Mandibular fractures are uncommon in children <6 yr of age; when they do occur, they are often greenstick fractures and can be managed with soft diet alone.
  • Inform parents that because any fracture of the mandible may damage permanent teeth, follow-up with a specialty consultant is advisable.
  • Refer pediatric patients to a specialist with experience in children due to issues with growth plates and permanent teeth.
