Figure 1From: Periodontal biomechanics: finite element simulations of closing stroke and power stroke in equine cheek teethForce application for closing stroke and power stroke. Forces were applied perpendicular to a plane through the alveolar crest for closing stroke (1a) and at an angle of 45° to this plane for power stroke (2a) . Force application occurs along the transverse ridges for power stroke (b).Back to article page
