Fig. 4From: A customized fixation plate with novel structure designed by topological optimization for mandibular angle fracture based on finite element analysisLoading and muscle areas on the mandible. Four kinds of mandible muscles were modeled as springs at the colored ovals, and the three green lines represented the three occlusal situations: loading I, incisor loading with 125 N, loading II, left second molar loading with 250 N, and loading III, right second molar loading with 250 NBack to article page
