Tip-Edge Plus双丝技术扭转力学性能三维有限元分析
Three-dimensional finite element analysis of torsional mechanical properties of Tip-Edge Plus twin wire technology
摘要
Abstract
To explore the torsion mechanical properties of Tip-Edge Plus brackets with double wire technique by using finite element method. Established the assembly models of Tip-Edge Plus brackets and different arch wire separately according to experimental groups. Then ran and calculated each model,collected relevant data. The results showed that when using the same material arch wires,the torsion moments of the double wire groups were greater than single round wires and when using different material arch wires,the torsion moment: 0. 014 NiTi + 0. 016 NiTi > 0. 020 Aus > 0. 018 Aus > 0. 014 NiTi + 0. 014 NiT > 0. 012 NiTi + 0. 016 NiTi > 0. 016 Aus > 0. 012 NiTi + 0. 014 NiTi > 0. 014 inch Aus. Therefore,with the application of auxiliary arch wire,the trends of the torsion moment increasing with torsion angle were obviously,and its amplitude increased more prominent when the auxiliary arch wire's sizes were increased. While the auxiliary arch wire size changed,the increased amplitude of the torsion moment was much bigger than the main arch wire size changed. Besides,in clinical application,orthodontists can use different couple of double wires according to the torsion of tooth.关键词
