[Application of a 3-dimensional model using computer technology in the study of the structure of the mandible].

Previous studies employing a plane "model" on the hemi-mandible confirmed the concept of a "bees-nest" structure of the mandible. As this plane model did not permit demonstration of maximal zones of iso-stress in the horizontal rami, the whole mandible was examined by means of a three-dimensional model. This gave more precise information, and thus produced more realistic results confirming previous findings. This new reliable type of model can be employed for any such exploratory procedure, and in studies totally different from those for which it was developed.
