Introduction And Importance:
Mandibular fractures are one of the most common sites of injuries and are difficult to restore in establishing preinjury occlusion and it is influenced by biomechanical principles. Open Reduction and Internal Fixation remain the gold standard in treating mandibular fractures to achieve pre-injury occlusion though it was limited toward expensive cost. As an option, closed reduction using an arch bar, wire, and elastic combination was preferred to establish functional preinjury occlusion.
Cases Presentation:
Patients came to University Hospital with chief complaints of pain and difficulties in mouth opening and mastication. From clinical and radiographic examination the first case with history of assault injury during martial arts was found unilateral left mandibular angle and right mandibular body fracture. In the second case with the history of motorcycle injury 11 days ago was found displaced right parasimphysis mandibular fracture.
Clinical Discussion:
All cases was treated with close reduction using dynamic elastic for gradual reposition and followed with wire fixation until occlusion was established. After the evaluation, functional occlusion and normal mouth opening was achieved.
Conclusion:
The selection of the therapy on multiple site fractures can be handled in a closed reduction with Intermaxillary Fixation which minimally invasive, low risk of nerve injury and give a good bone remodeling process and can restore mandibular function according to anatomy.
