Figure 2. Deformations of the mid-sagittal cross-section of the condyle due to the three loads. The gray area indicates the unloaded shape. The lines depict the deformed shapes. For reasons of clarity, these deformations were amplified 50 times. At the bottom, the deformation was zero, because the saw plane was fixed during the simulation. The thick lines mark the region where the loads were applied.

Figure 3. Total principal strain and the principal strains for the thee different load cases. The total principal strain is indicated with colors. The color bar gives the total principal strain in µstrain. The orientations and magnitudes of the principal strains in the sagittal plain are indicated with the black lines. The strains of only a random selection of the elements are shown.
