Biomechanical Advantage and Disadvantage of Different Sinus Systems

Caption

The well-developed sinus system in the now extinct cave bear (top left) is associated with uneven mechanical stress distributions in biting simulations (bottom left) conducted at UB. The much less developed sinus system in living bears, for example the sun or honey bear, (top right) allows mechanical stress to distribute evenly over the forehead region, as seen in the biting simulation (bottom right).
