FEM Analysis of Mini-Plate for Osteosynthesis of Mandibular Fractures Dedicated for Future Manufacturing with Additive Technologies (AM)

The purpose of this study was to design a 3D geometry of mini-plate for mandibular angle fracture, based on biomechanical properties, that will be possible to manufacture with additive technologies (AM). Three types of internal structures (lattice, cross and honey comb) were selected and compare the results of displacement and von Mises stress distributions based on Finite Element Method (FEM). The results show that the mini-plate with optimal structure (cross-shaped) for which the thickness of struts was applied at the level of 0.5 mm is characterized with best properties can be fabricated with use of AM to satisfy the urgent time requirements for treatment.
