[A comparative study of 2 series of mandibular osteosynthesis using screwed plates].

In a retrospective study, we compared monocortical internal fixation versus bicortical screwing in the treatment of the mandibular fractures. Between 1983 and 1985, 40 patients underwent bicortical screw plate osteosynthesis and 46 were treated with the monocortical screw plate technique. The results are favorable to bicortical screwing, as regards both infection and pseudarthrosis. Monocortical screwing caused fewer occlusal disorders than bicortical screwing. Best on the increased amount of complications we decided to abandon the using of monocortical in favour with bicortical plates.
