| 摘 要： | 目的:建立包含不同长度标准直径种植体的下颌骨三维有限元模型,分析不同长度种植体对即刻负载种植体骨界面应力应变分布的影响.方法:采用薄层CT扫描下颌骨和自主开发的USIS软件建立直径4.1mm不同长度螺纹种植体即刻负载的三维有限元模型,用ANSYS软件分析长度分别为6、8、10、12、14mm的种植体,在垂直和颊舌向45o加载150N力时种植体骨界面的von Mises应力、应变值.结果:随着种植体长度的增加,种植体骨界面的应力和应变值均呈下降趋势.种植体骨界面应力值在长度从6mm增加到8mm时下降最明显,尤其是颊舌向加载时;而种植体长度从8mm增加到10mm及从10mm增加到12mm和从12mm增加到14mm时,骨界面应力值下降并不很明显.种植体骨界面应变值也是在长度从6mm增加到8mm及8mm增加到10mm时下降最明显.结论:种植体长度的增加能降低骨界面应力和应变值,呈负相关关系;但只在长度从6mm增加到8mm时应力值降低才较明显.这提示临床上尽量不要采用长度为6mm的种植体,并应适当地选择足够长度的种植体.
