The use of porcine rib pairs as an in vitro analog for the edentulous mandible is described. Using this model, the relative degree of fixation achieved with a screw plate (Champy) and a paraskeletal clamp plate (Mennen) has been evaluated. The fractured plated ribs failed at significantly lower bending forces than the non-sectioned controls. However, no statistically significant difference in force at failure between the two different methods of plate fixation could be demonstrated.
描述了使用猪肋骨对作为无牙下颌骨的体外模拟物。利用该模型，评估了使用螺钉板（Champy）和副骨骼夹板（Mennen）实现的相对固定程度。与未切开的对照相比，骨折固定的肋骨在显著更低的弯曲力作用下失效。然而，两种不同的钢板固定方法在失效时的力方面没有显示出统计学上的显著差异。
