Abstract :
Two types of two-dimensional physical models have been developed to simulate bone and the surrounding soft tissues and evaluate the effectiveness of various cushions in relieving stress concentrations in the soft tissue. The stresses were derived from deformation data obtained from photographs of grids etched on the models. Results indicate that the flat-edge bone core generated large sheer stress and lower compressive stress magnitudes when compared to a round-edge bone core. The enveloping property of the cushion played an important role in providing stress relief
