The stress distribution in an edentulous mandible provided with two implants in the interforaminal region was calculated by means of three different finite element models. The implants were connected with a bar or remained solitary. The first model was a three-dimensional representation of the entire mandible, the second model of the interforaminal region of this same mandible, whilst the third model was a two-dimensional representation of the interforaminal region. The differences in stress distribution around the connected implants and the solitary implants between these three models were analysed. It can be concluded that for a parameter study the stress distribution around the dental implants following from a three-dimensional finite element model of only the interforaminal region of an edentulous mandible can be used. For such studies therefore, benefit can be gained from the advantages of reduced modelling and calculation time.
采用三种不同的有限元模型计算了在无牙下颌骨孔间区域植入两颗种植体时的应力分布情况。种植体通过杆连接或保持独立。第一个模型是整个下颌骨的三维表示，第二个模型是同一下颌骨孔间区域的模型，而第三个模型是孔间区域的二维表示。分析了这三种模型中连接种植体和独立种植体周围应力分布的差异。可以得出结论，对于参数研究，可以使用仅关于无牙下颌骨孔间区域的三维有限元模型得出的牙种植体周围的应力分布。因此，对于此类研究，可以从减少建模和计算时间的优势中获益。
