[The value of an osteosynthesis arch-plate combination in the application zone in the treatment of fractures of the body of the mandible].
Fractures of the tooth-bearing part of the mandibular body require both orthopedic stabilization of the maxillomandibular joint and surgical fixation. From an evaluation of the anatomic and biomechanical features of the mandible, we propose the notion of a useful zone for fixation. The useful zone is basically submitted to traction forces and includes both the teeth and the teeth-bearing bone situated above the mandibular canal in the body and the entire symphysis. Applying an arch-plate on the useful zone has the advantage of providing initial stability, progressive loading and reduction in risk of displacement or secondary infection. This therapeutic approach gives better results than simple plate fixation.
