<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;"><span style="color: black;">皮质骨:</span></strong><span style="color: black;">又<span style="color: black;">叫作</span>为骨密质,其质地致密,抗压强度、抗扭曲性能均较强,<span style="color: black;">重点</span><span style="color: black;">位置于</span>骨的外层,内层<span style="color: black;">重点</span>是松质骨;皮质骨中骨板呈同心圆<span style="color: black;">摆列</span>,其包饶的小腔内环绕着中央哈佛管,其内<span style="color: black;">包括</span>血管及神经,骨组织从中得到营养。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;"><span style="color: black;">位移:</span></strong><span style="color: black;">组织在力学环境下会<span style="color: black;">出现</span>空间位置的改变,任意一点位移<span style="color: black;">指的是</span>该点从最初位置至最末位置的空间距离和方向,位移是矢量。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;"><span style="color: black;">背景:</span></strong><span style="color: black;">关于皮质骨厚度的改变对位移值及等效应力值影响的三维有限元<span style="color: black;">科研</span>较少。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;"><span style="color: black;">目的:</span></strong><span style="color: black;"><span style="color: black;">经过</span>三维有限元<span style="color: black;">办法</span>分析<span style="color: black;">区别</span>皮质骨厚度对种植体-骨界面位移及应力分布的影响,为口腔种植治疗<span style="color: black;">供给</span><span style="color: black;">必定</span>的<span style="color: black;">意见</span>。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;"><span style="color: black;"><span style="color: black;">办法</span>:</span></strong><span style="color: black;"><span style="color: black;">选择</span>1例拟行下颌<span style="color: black;">第1</span>磨牙种植修复男性<span style="color: black;">病人</span>(27岁)的锥形束CT影像资料,<span style="color: black;">首要</span>在Mimics 13.0软件<span style="color: black;">创立</span>下颌骨模型,<span style="color: black;">而后</span>导入Solid works 2022软件中,<span style="color: black;">按照</span><span style="color: black;">关联</span><span style="color: black;">制品</span>信息绘制出锥形种植体(4.1 mm×10 mm)及上部修复体模型,<span style="color: black;">按照</span><span style="color: black;">区别</span>皮质骨厚度(2.5,2.0,1.5,1.0 mm)<span style="color: black;">得到</span>皮质骨模型,分别命名为D1,D2,D3,D4,将所有模型导入ANSYS Workbench 2021软件中并交叉组合,最后对4组模型静态载荷,分析各组模型受力后的应力分布。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;"><span style="color: black;">结果与结论:</span></strong><span style="color: black;">①等效应力峰值在松质骨最小,在上部修复体即基台-种植体连接处最高;②整体等效应力峰值随着皮质骨厚度减小而<span style="color: black;">升高</span>;③基台处等效应力峰值会随着皮质骨厚度减小而增大,类似的解释<span style="color: black;">亦</span>适用于其他种植修复部件;④骨组织和种植体中应力峰值随着皮质骨厚度的<span style="color: black;">增多</span>而<span style="color: black;">增多</span>,并且在D1,D2,D3中种植体应力峰值大于骨组织,D4相反。</span></p>
