Feasibility of carbon-fiber-reinforced polymer fixation plates for treatment of atrophic mandibular fracture: a finite element method

The objective of this study was to conduct a computer assessment of the biomechanical stability of locking fixation plates of different thicknesses, made of titanium alloy and carbon-fiber- reinforced polyetheretherkotone (CFR-PEEK) in Class III atrophic mandibular fractures. Class III atrophic mandibular models were constructed using three-dimensional finite element models. After simulation of fracture on the left side, plates with different thicknesses (1.0, 1.5, 2.0, and 2.5 mm) were adapted to the models and three locking screws on each side of the fracture were used for fixation.
