Figure 3From: Periodontal biomechanics: finite element simulations of closing stroke and power stroke in equine cheek teethStrain energy density occurring in the PDL during closing stroke. A load of 350N was applied along the tooth’s longitudinal axis. Diagram shows FE results for the three different age groups (A-C) on both the shifting side (1) and side where shifting side is averted (2). Dimension of SED increases with increasing tooth age (to this please note the different age-related scales).Back to article page
