The objective of this study was to simulate different vertical and anteroposterior positions of the expander screw of hyrax appliance and assess the displacement of the teeth and the patterns of distribution of forces in the periodontal ligament using the finite element method (FEM). The part of the maxilla with teeth, periodontal ligament, midpalatal suture, and the hyrax appliance were modeled, and 6 distinct FEM were created to simulate different positions of the expansion screw.There were 2 vertical positions at distances of 20 and 15 mm from the occlusal plane. Another 3 positions were anteroposterior, with the center of the screw placed between and equidistant from the mesial face of the first molar and the distal face of the ...
