本文采用平面光弹性方法对下颌第一磨牙缺失的两基牙双端固定桥、半固定桥、三基牙双端固定桥、有邻牙的两基牙双端固定桥以及未修复牙的受力情况进行了实验研究,得出了固定桥基牙垂直支反力的分配比例和各类修复体基牙牙槽骨的应力条纹图。结果表明:
In this paper, the two-abutment double-ended fixed bridge, the semi-fixed bridge, the three abutment double-ended fixed bridge, the two abutment fixed double-ended abutments with adjacent teeth and the uncorrected teeth Force situation of the experimental study, obtained the fixed bridge abutment vertical reaction force distribution ratio and various types of restoration abutment alveolar bone stress fringes. The results show:
