This study aims to compare the biomechanical behavior of different fixation configurations, involving either only prebent plates or prebent plates combined with mini- or micro-L-plates, using three-dimensional (3D) finite element analysis (FEA) following Le Fort I osteotomy with 5 mm advancement and 4 mm inferior repositioning. In Model 1, two prebent plates were bilaterally positioned at the piriform aperture. Model 2 included the same configuration, supplemented with two mini-L-plates. In Model 3, the prebent plates were combined with two micro-L-plates. Static loads were applied to the models in vertical, oblique, and horizontal directions. The von Mises stresses, maximum and minimum principal stresses (Pmax and Pmin), and displacements were calculated. Model 2 had the lowest displacement values. The mini-L-plates demonstrated the lowest von Mises stress among all plates. Model 2 was found to be the most stable at all measured points. The stress values in Model 1 and Model 3 were found to be similar, indicating that combining prebent plates with micro-L-plates does not provide a significant mechanical benefit. When additional fixation to prebent plates is required, the use of mini-L-plates reduces von Mises stresses and improves stability.
