种植体贯通下颌骨三维有限元分析

The 3D-FEM Analysis of Transmandible Dental Implants

采用三维有限元方法分析研究4个种植体(种植体颈部之间加连接板)穿通下颌骨时,骨界面的应力分布.对比在下颌骨的下表面不加连接板与加连接板两种情况,探讨种植体穿通下颌骨对骨界面应力分布的影响.计算结果表明下颌骨的下表面加连接板可以减小骨界面的应力,有利于下颌骨的受力.

In order to explore the effect on the stress distribution within bone surrounding implants with a plate under the lower margin of mandible, the author compared the stress magnitudes around the four implants with a plate and without a plate under the lower margin of mandible . The results indicated with a plate under the lower margin of mandible the stress around the implants can be minimized. It can improve the stress distribution of the mandible.
