Biomechanical evaluation of different fixation techniques in the rotation of the maxillary occlusal plane after Le Fort I osteotomy.

Background: To analyze the biomechanical and functional characteristics of different maxillary fixation techniques after Le Fort I osteotomy and occlusal plane rotation, using the finite element method to simulate the mechanical behavior of three different osteosynthesis approaches.

Material And Methods: This is a virtual experimental study carried out using finite element analysis to compare three different osteosynthesis techniques after Le Fort I osteotomy and rotation of the maxillary occlusal plane. Three configurations were tested: four-point fixation with "L" plates (C1), two-point fixation with "L" plates (C2), and two-point fixation with pre-modeled Lindorf plates (C3).
