Fracture is a medical term used to describe the broken bone. Whenever their is a discontinuity of bone , its results in sever pain  and  this dis-continuity in bone  is reffered as fracture( A Break In The Bone ). This is usually due to direct hit trauma to bone.

                          Although, the lower jaw bone (or Mandible) is one of the strongest bone in human body. But when is comes to facial injury , the broken jaw is the 10th most common fractured bone in human body. Whenever there is a direct hit to lower jaw happens , jaw fracture may occure.

Types Of Fracture

Mandibular fractures can be classified into following types according to their extant and communications to external environment:


Greenstick fractures are incomplete fractures of flexible bone, and for this reason typically occur only in children. This type of fracture generally has limited mobility.

Simple Fracture:

A simple fracture describes a complete transection of the bone with minimal fragmentation at the fracture site.


The opposite of a simple fracture is a comminuted fracture, where the bone has been shattered into fragments, or there are secondary fractures along the main fracture lines. High velocity injuries (e.g. those caused by bullets, improvised explosive devices, etc…) will frequently cause comminuted fractures.


A compound fracture is one that communicates with the external environment. In the case of mandibular fractures, communication may occur through the skin of the face or with the oral cavity. Mandibular fractures that involve the tooth-bearing portion of the jaw are by definition compound fractures,[17] because there is at least a communication via the periodontal ligament with the oral cavity and with more displaced fractures there may be frank tearing of the gingival and alveolar mucosa.

Symptoms of a dislocated Jaw includes

  • Pain in the face or jaw, located in front of the ear or on the affected side, that gets worse with movement.
  • Bite that feels “off” or crooked.
  • Problems talking.
  • Inability to close the mouth.
  • Drooling because of inability to close the mouth.
  • Locked jaw or jaw that protrudes forward.


Broken Jaw Symptoms :

        You may feel that your teeth do not fit together correctly (this is called a malocclusion). You may be unable to open your jaw all the way, have problems speaking, or notice swelling of the jaw. Your chin or lower lip may be numb because of damage to a nerve that runs through the mandible. If You find any one of the above feature after accident consult your dentist as soon as possible.


                  Treatment for a fractured jaw depends on how badly the bone is broken. If you have a minor fracture, it can heal on its own. If the fracture lies in teeth region the jaw may be wired to the teeth of the opposite jaw to keep the jaw stable while it heals. Jaw wires are usually left in place for 6 to 8 weeks. If the bone fragents are torn apart bone plating may be required to fix the fracture. No of fragments decides the number of plate required.
