[Accuracy of apposition achieved by mandibular osteosyntheses. Stereophotogrammetric study]

The accuracy of apposition achieved by wire and plate osteosyntheses is measured with the aid of close range stereophotogrammetry in the mandibles of dead bodies. Both osteosynthesis methods are characterized by an increase in the intercondylar distance which, on the average, is about 3.3 mm greater after plate osteosynthesis and about 1.9 mm after wiring. Moreover, osteosyntheses of the base of the mandible may involve a tendency of the condyle to become caudally dislocated.
