FIGURE 4.
The von Misses stress distribution on 5 implants in dual-leg standing. For Plate-Screw system, the maximum von Misses stress occurred at a place where it strides over pubic symphysis and adjacent Plate-Screw joints. The maximum von Misses stress with the cannulated screw system occurred at the thread-cortical bone interface. Stress concentration appeared on Plate-Screw system, whereas stress equidistribution was observed in the caudomedial part of cannulated screws.
