Introduction: The atrophic edentulous mandible is more predisposed to fractures, and in high impact traumas — such as perforations by firearms, which causes comminuted fractures —, require surgical treatment with a supported load reconstruction plate, for a more stable osteosynthesis, obtaining better treatment results and recovering the shape and function of the mandible. Objective: The objective of this study is to report a clinical case of a patient victim of firearm accident in a partially edentulous mandible with mild atrophy, corrected with supported load reconstruction plate. At 40-day postoperative follow-up, the patient presented preserved occlusion, with plaque and screws in position — as seen in radiographic examination —, moderate edema, without pain complaint, absence of motor nerve damage, but with sensitive nerve dam- age. Conclusion: The treatment with open reduction and rigid internal fixation with 2.3mm Locking® system of supported load demonstrates good result, with adequate functional restoration in comminuted fracture due to firearm lesion in atrophic mandible.
