Biomechanical analysis in the internal structure of jaw bone for prevention of dental implant failure

为了评估种植体的放置位置，防止多次种植体失败，我们使用micro-CT进行三维测量和生物力学分析，观察解剖结构，阐明功能压力对通过种植体的颌骨内部结构的影响。3d重建图像显示颌骨结构复杂，植入种植牙时必须小心。在有限元分析中，我们可视化了载荷传递路径，结果表明种植体周围的骨小梁重新排列被认为在支撑压力方面起着重要作用。研究松质骨的结构特性，包括应力分析，将有助于预测可接受的骨内植入物负荷。

To evaluate the sites for dental implant placement and prevent several implant failure, we used micro-CT for 3D measurement and biomechanical analysis to observe anatomical constructions and to clarify the influence of functional pressure on the internal structure of the jaw bone through implant. The 3D-reconstructed images revealed that jaw bone had a complex structure, and care must be exercised when inserting dental implants. In the finite element analysis, we visualized load transfer paths, and the results suggested that trabecular bone realignment around an implant is thought to play an important role in supporting the pressure. And examination of the structural properties of cancellous bone including stress analysis would be useful in predicting acceptable loads of endosseous implants.
