The internal bony structure of ten dentate human mandibles was examined on lateral radiograms, and the condylar shape measured with a digital electronic machine. The external surface was coated with photoelastic material. Each mandible was then placed in centric occlusion with brass replicas of the upper arch and the glenoid fossae and set in a supporting frame. Occlusal loads were simulated and the isoclinics recorded in plane-polarized light. The isostatic flow lines were constructed for each mandible. A relation was found between the mandibular structure and the distribution pattern of these lines.
