[Experiences with the 3-D miniplate osteosynthesis in mandibular fractures].

A geometrically closed quadrangular plate secured with bone screws creates stability in three dimensions. The smallest structural component of a 3-D-plate is an open cube or a square stone. Our clinical results and biomechanical investigations have shown a good stability of the 3-D-plates in the osteosynthesis of mandibular fractures without major complications. The thin 1.0 mm connecting arms of the plate allow easy adaptation to the bone without distortion. The free areas between the arms permit good blood supply to the bone.
