ORIF remains the gold standard for managing displaced mandibular fractures, especially in functionally demanding patients. Success depends on proper case selection, precise anatomic reduction, stable fixation, and diligent postoperative care. Biomechanical principles, such as load-sharing versus load-bearing fixation, play a critical role in selecting the appropriate hardware. Adherence to Champy's lines of osteosynthesis ensures optimal stability and minimal interference with surrounding structures. Early mobilization, restoration of occlusion, and prevention of infection are key to achieving favorable functional and aesthetic outcomes.
