Torque Control of Upper Incisor in Intrusive Loads and Comparison of the Lingual and Labial Bracket Systems: A Finite Element Analysis

Abstract

Torque Control of Upper Incisor in Intrusive Loads and Comparison of the Lingual and Labial Bracket Systems: A Finite Element Analysis

The aim of present study was to investigate the difference of torque control during intrusion force in incisors with normal, under and over-torque in lingual and labial orthodontic systems through finite element analysis. 3D models of an upper right central incisor with different torques were designed in Solid Works 2006.The models were transferred to the ANSYS Workbench Version 12.1.An intrusive force of 0.15 N was applied to the bracket slot in different models and the displacements along a path of nodes in the central incisor was assessed.
