Mandibular fracture after a dentist procedure.

Introduction: Mandibular fractures are classified according to location, variety, and fracture line direction. Mandible fracture is described as an uncommon complication after mandibular retromolar trigone surgery, being associated with iatrogenic damage requiring surgical correction. Objectives: Report the case of a patient undergoing an emergency surgical reduction with bone fixation, intermaxillary blockage of a simple fracture of the mandible after a dental procedure. Resumed report: Male, 54 years old. Reports procedure by a dentist in the topography of the lower right third molar for bone graft removal. 5 days after the procedure, when ingesting food of rigid consistency, the patient reported toothache, associated with trismus. Contrasted tomography of the skull showed a simple fracture of the angle of the mandible, probably due to iatrogenesis. Urgent surgical procedure. Findings and description of the procedure: Subperiosteal dissection with a dissector tip and identification of a mandibular angle fracture with a bone defect in the anterior region. Maxillomandibular immobilization was performed with 6 IMF locking screws. Fracture reduction. Applied 2 plates with 4 holes 2.0 in distal and proximal regions of the fracture, fixed with 8 screws through a trocar. Removed blockage and screws with occlusion testing maneuver. Intra and extra oral sutures. Post-op was uneventful and with full recovery. Conclusion: Mandibular fracture due to iatrogenic damage after procedures on the mandibular third molar has low prevalence and high severity, the ideal approach should occur as early as possible through surgical reduction with bone fixation.
