Intervention 1: Intervention group: The patients in intervention group, firstly underwent local anesthesia, then the arch bars of maxilla and mandible are closed, mandible bone fracture was reduced using closed reduction, after establishing primary occlusion the strong elastics (3/16 inch- 6/5 oz) were applied and then IMF (intermaxillary fixation) was performed in an appropriate occlusion. Pulsed electromagnetic field was administered for 10 min/day for 10 days after reduction. Intervention 2: Control group: The patients in control group, firstly underwent local anesthesia, then the arch bars of maxilla and mandible are closed, mandible bone fracture was reduced using closed reduction, after establishing primary occlusion the strong elastics (3/16 inch- 6/5 oz) were applied and then IMF (intermaxillary fixation) was performed in an appropriate occlusion. No pulsed electromagnetic field was administered for the control group after reduction.
