Maxillary and mandibular fractures are a relatively frequent occurrence due to the exposed location of the jaws and are caused mainly by acts of violence, traffic and recreational accidents. Mandibular fractures can be treated conservatively with dental splints and intermaxillary fixation. Since Michelet, miniplate osteosynthesis via intraoral access has become the method of choice. Champy showed that the monocortical fixation of miniplates at the level of the linea obliqua results in stable osteosynthesis, despite postoperative micro-movements in the fracture gap, and postulated the principle of dynamic compression. Dislocated fractures of the mandibular collum are treated with stable osteosynthesis via an intra- or extraoral approach, while fractures of the mandibular joint are usually treated conservatively and early functional rehabilitation is favored. For mandibular fractures, the principle of load-bearing and load-sharing should be considered, i.e. in the case of sufficient bone and uncomplicated fractures, the bone can bear most of the force, such that miniplates are sufficient (load-sharing). If bones are weakened by atrophy or in the case of infected, comminuted or defect fractures osteosynthesis plates must bear the load alone (load-bearing).
