Biomechanical Behavior of Different Miniplate Designs for Skeletal Anchorage in the Anterior Open Bite Treatment

This study aimed to evaluate the stress distribution and mechanical behavior of miniplate designs skeletal anchorage for treatment anterior open bite in adult patients. A complete hemimaxilla, teeth, brackets, transpalatal bar, three miniplates were virtually modeled. I-, Y-, T-shaped installed area alveolar zygomatic crest. The assembly was constricted intrusive forces (2, 4, 6 N) applied maxillary molars according miniplates. All materials considered homogeneous, elastic, linear; mesh 1,800,000 hexahedrons with 2,800,000 nodes on average. Displacement, maximum principal stress, von Mises evaluated shape device force. configurations resulted different displacement intensities bone tissue plate; these stresses always located same regions within physiological limits. Y-plate showed best performance since its application generated less displacement.
