Biomechanical studies on a model of the mandible served to verify the stability of a fracture treated with the techniques of pressure-plate osteosynthesis, traction-bandage osteosynthesis and percutaneous compression osteosynthesis, respectively. Stress distribution in the model were determined photoelastically. In this way, it has been possible to obtain informations about stresses caused by different loads (biting-off, stress on the left or right lateral region). Of the methods of osteosynthesis under investigation, plate osteosynthesis yielded the most stable union of the fragments. Satisfactory values were also achieved by means of traction-bandage osteosynthesis and percutaneous compression osteosynthesis. Consequently, these methods may be regarded as function-stable. Conclusions as to the optimal location of the osteosynthesis material can be drawn from an exact analysis of the stress curves. Maximum stress on the mandible, especially in the anterior region, should be avoided for a least 3 weeks.
对下颌骨模型进行的生物力学研究，旨在分别验证采用加压接骨板骨合成技术、牵引绷带骨合成技术和经皮加压骨合成技术治疗骨折的稳定性。通过光弹性法测定模型中的应力分布。通过这种方式，得以获取关于不同负荷（咬断、左右侧区域应力）所产生应力的信息。在所研究的骨合成方法中，接骨板骨合成能使骨折碎片实现最稳定的愈合。牵引绷带骨合成和经皮加压骨合成也取得了令人满意的结果。因此，这些方法可被视为功能稳定的方法。通过对应力曲线的精确分析，可以得出关于骨合成材料最佳位置的结论。下颌骨上的最大应力，尤其是在前部区域，至少应避免3周。
