The PDLs, which have an hourglass shape naturally, had a uniform thickness of 0.2 mm, as was used in previous FEM studies.16 The ligament layer was further divided into two uniform layers of 0.1-mm Discrepancy Index (DI) This index used to evaluate the difficulty of the cases presented for the American Board of Orthodontics examination.
