The Max EQV stresses in jaw bone and Max displacements in implant-abutment complex were set as evaluation targets .

应用皮质骨和松质骨的EQV应力峰值和种植体&基台复合体的位移峰值为评估指标。

The way accords with the national standard GB 4706.1 1998 ( eqv . IEC335 1:1991 )《 Safety of household and similar electrical appliances Partl : General requirements 》 .

该方法符合国标GB4706.11998（等同于IEC3351：1991标准）《家用和类似用途电器的安全第1部分：通用要求》中的相关规定。

Under bucco-lingual load , the amplification of maximum EQV stresses in cortical bone , cancellous bone and implant were 2.8 % , 28.8 % and 14.9 % respectively .

在颊舌向加载中皮质骨、松质骨和种植体的EQV增幅分别为2.8%、28.8%和14.9%；

The results showed that the max EQV stresses in cortical and cancellous bones decreased by 46.5 % and 98.8 % respectively with T and E increasing , and the max displacement of mini-implant decreased by 70.2 % .

随着T和E的增加，皮质骨、松质骨EQV应力峰值分别下降46.5%和98.8%，微种植体位移峰值下降70.2%。

When P exceeded 0.8 mm , the response curve curvature of maximum EQV stresses in jaw bone and in implant to P was ranged from-1 to 1.Conclusion Stresses in cancellous bone are more sensitive to thread pitch than in cortical bone .

在各种加载情况下，当变量P大于0.8mm时，对颌骨及种植体的EQV应力峰值响应曲线曲率位于-1和1之间。

Methods Finite element models of segment jaw bone with a V-shaped thread implant were created . The thread pitch ( P ) was set from 0.5 mm to 1.6 mm . The maximum Equivalent stresses ( EQV stresses ) in jaw bone and in implant were evaluated .

方法建立了包含圆柱状V形螺纹种植体的颌骨骨块三维有限元模型，设定螺纹螺距（P）范围为0.5～1.6mm，观察P变化对颌骨和种植体Equivalen（tEQV）应力峰值的影响。
