The loading capacity of teeth is determined by various factors. Apart from size and quality of the surfaces to which force is transmitted, the shape of the root and how far it is inserted are especially important. It was found that primarily teeth with cylindrical roots can accept greater masticatory forces than teeth with tapered roots and react to a considerably smaller extent if the root is not deeply inserted. If the force applies outside the longitudinal axis running through the center of gravity, the loading capacity decreases with increasing distance.
