Clear aligner treatment is considered to be helpful for periodontitis orthodontics because these aligners are easy to wear and take off. However, studies have shown that the instantaneous force associated with such aligners may affect periodontal tissues. The goal of this study was to identify the optimal orthodontic displacement of clear aligners concerning torque movement using a Three-Dimensional (3D) finite element. We acquired Cone Beam Computed Tomography (CBCT) data from a patient without diabetes and other systemic diseases and who received invisible orthodontics. Based on the different degrees of alveolar bone absorption (1/3 and 1/2 of the root length were reduced horizontally from the alveolar crest along the Z-axis to form alveolar bone models with different degrees of absorption (M1, M2, and M3)), 3D-FEMs of the mandible were established using MIMICS 10.0 and ABAQUS 6.5 s..
