Comparison of the biomechanical properties of internal fixation materials for zygomaticomaxillary complex fractures, A finite element analysis
Regarding the three distinct types of zygomaticomaxillary complex (ZMC) fractures, this study developed finite element models (FEMs) of absorbable material and titanium material for repair and fixation, respectively. By applying a force of 120 N to the model to simulate the masseter muscle strength, the maximum stress and displacement of the repair materials and the fracture ends were measured. In discussing various models, the maximum stress values of absorbable and titanium materials are less than their yield strength, and the maximum displacement values of the titanium material and fracture end were less than 0.1 mm and 0.2 mm. The maximum displacement values of absorbable material and fracture end in incomplete zygomatic fracture and dislocation were less than 0.1 mm and 0.2 mm. While in the zygomatic complex complete fractures and dislocation, the maximum displacement values of the absorbable material and the fracture end exceeded 0.1 mm and 0.2 mm. Consequently, the distinction between the maximum displacement values of the two materials was 0.08 mm, and the distinction between the maximum displacement values of the fracture ends was 0.22 mm, despite the fact that the absorbable material can withstand the fracture end's strength, it is not as stable as the titanium material.
