Mandibular fracture

 

  • Transverse fracture through the body or through both rami near the symphysis
    • Wiring incisors to the first molars may be useful in conjunction with an apparatus to form a ‘V’ fixed to the lower jaw.
    • The apex ‘v’ being spoon – shaped to support the chin and its branches being grooved to adapt themselves to the horizontal rami.
    • Wire sutures through the bone are the best means of immobilizing the seat of fracture.
    • In condition of necrosis of bone , amputation may be done.
  • Fracture of  ramus on one side
    • Requires no treatment , because of rare chance of displacement.
    • A blister may be applied on the skin at the level of fracture. Blister cause additional inflammation and hyperemia, which hastens the healing process.
    • In all cases of fracture of jaws, soft easily masticated food is indicated.
