1 Treatment top

Closed treatment of simple fractures of the angle enlarge

Arch bars are applied to the teeth and MMF is secured. The patient is monitored for positional changes of the mandibular ramus using x-rays. At 6 weeks MMF is released and fracture stability determined by manipulation. The patient is placed on a soft diet and if the occlusion maintains for a two-week period, the arch bars may be removed.
