[Physical factors in tissue injuries of the masticatory organ].

For the analysis of tissue trauma physical quantities and mechanisms were registered by means of electronic measuring devices in the model example of jaw fractures. Samples of pig jaws were subjected to load until breaking by a pendulum hammer: by impulse loading of the teeth and the jaw bone itself. Using oscillograms of the deformations of the teeth and jaws and force, the most important biophysical quantities of this trauma are explained: impact speed, impulse, force, tissue deformation, increase of force.
