Fig. 5From: A customized fixation plate with novel structure designed by topological optimization for mandibular angle fracture based on finite element analysisTwo typical fixation systems for mandibular angle fracture. a Type A, one mini-plate fixed at the tension zone according to Champy’s technique, and b type B, upper mini-plate fixed at the same place of previous treatment, and a lower mini-plate fixed at the inferior border of the mandibleBack to article page
