This example shows the different response of a cylindrical threaded implant for a wide variation of the upper cortical layer. All the models considered have the same elastic constants and loading conditions.
Different values of the Young's modulus are assumed for the regions of bone around the implant. The Young's modulus in the implant-cortical transition region is set at 5.0 GPa and at 1.5 GPa in the implant-trabecular region. The cortical bone thickness is 1 mm for the model of Fig. 1, 1.5 mm for the model of Fig. 2, 2 mm for the model of Fig. 3 and 2.6 mm for the model of Fig. 4.
An intrusive force of 200 N is applied.
The magnitude displacement fields are reported for the four cases considered .
