In this case, we tried to use the alveolar bone splitting technique with the Piezosurgery, and the incison line was put in the alveolar ridge as lingually as possible that the integrity of the cortical plate of the alveolar ridge is reserved in the buccal side. Because the resistance to the mesial movement of the posterior teeth is greatly decreased, the possibility of the root resorption or dehiscence is reduced, and the stability after the orthodontic treatment would be improved while the height and width of the alveolar bone increase.

本病例尝试以超音波骨刀，於缺牙区进行齿槽骨劈开手术，其切线尽可能靠近齿槽之舌侧，以使齿槽上的皮质骨板可完整置於颊侧；这样当后牙向前牵引时，才不会因皮质骨板而阻碍前进及牙根被吸收或裂开，同时也能增加齿槽骨之高度与宽度，亦可使矫正后的牙齿更加稳定。

At the same time, under the condition of small strain, firstly, the secant shear modulus was always larger than the tangent shear modulus. Secondly, when the logarithmic coordinates were applied to describe shear strain, the decrease of shear modulus with shear strain could be expressed by reversed S shape curve with two inflexion points, and through analyzing and validating, the deduced equation could perfectly reflect this characteristic. Finally, different stress paths and strain areas would lead to different attenuation trends.

而且，在小应变范围内，割线剪切模量总是大于切线剪切模量；当剪切应变采用对数坐标表示时，剪切模量随着剪切应变的增加而衰减，且衰减的规律都可以表示为带有两个拐点的反S型曲线，经分析验证本文所得公式3可以对此特性进行很好地反映；但应力路径、应变范围不同其衰减幅度不同。
