Functionally stable osteosynthesis in the mandible

The static and functional relationships of the mandible cause special problems for a stable plate osteosynthesis. For anatomic reasons, the traction strapping necessary in the alveolar crest region is very frequently impossible to carry out. Thus, a special plate was developed for compression osteosynthesis of the mandible. The plate has two functional parts. The center part permits a compression osteosynthesis in the body of the mandible by use of an axial compression thread. The fragments are additionally fixed by inserting a notched inlay section in the bone. The ends of the plate have a DCP hole projecting upward at an angle. This prevents cleavage secondarily in the fracture fissure away from the plate.
