In chronically infected simple fractures, resorption at the fracture site or debridement of the fracture gap may result in a small continuity defect and loss of buttressing of the mandibular fragments. A load-bearing plate must be used to ensure primary stability at the fracture site and uneventful fracture healing, with or without bone grafting.
General guidelines for these procedures is given here:
Body fractures in the severely atrophic mandible (< 10 mm mandibular height) will not provide adequate buttressing to allow the use of load-sharing hardware. A large load-bearing plate must be used to provide adequate fixation and uneventful healing.
