Figure 7.

Color plots of differences in strain magnitudes found in the periodontal ligament of FEMs that include (PDL Model) and exclude (NO PDL Model) the PDL. Pairs of FEMs are compared by mapping the surface distribution of element level differences in principal strains between the two models onto the teeth and the models are shown in four views. (A) Shows differences in ε₁ and ε₂ principal strains magnitudes. (B) Shows differences in sagittal (ε₁₂), frontal (ε₁₃), and transverse (ε₂₃) shear strain magnitudes between model pairs in four views. Scale bars to the right of each panel indicate the element level difference in strains (με) between models. Areas of greater difference in results from PDL and NO PDL models are indicated by darker colors, while lighter colors indicate areas of high similarity.
