自锁托槽配合双丝技术倾斜力学性能的三维数字化分析
A three-dimensional finite element analysis of the tip mechanical capabilities of self-ligating brackets with double wires
摘要
Abstract
BACKGROUND: At present, the using of self-ligating brackets is more and more extensive. But it is unclear about the rules and mechanisms underlying the tooth control by double wires in three dimensions, especially in tipping.OBJECTIVE: Using the finite element method to establish different three-dimensional finite models of DamonQ brackets and archwires with different sizes, and then to explore the tip mechanical properties when using double wire technique. METHODS: Different three-dimensional finite models of DamonQ brackets and archwires with different sizes were established by Pro/E Wildfire5.0. The models were assembled and imported to MSC.Marc.Mentat2005R3 followed by simulating the tip load, calculating torque moment and drawing the corresponding graph and histogram. RESULTS AND CONCLUSION: (1) With tipping movement of single wire, tipping moment of auxiliary single archwires was multiplied by the same size as main archwires. (2) With tipping movement of double wires, the tip moment value increased when the size of the main or auxiliary archwire increased, and the influence of the size of the auxiliary archwire was greater than that of the main archwire. (3) When the tilt angle is large, we can simply level the tooth using the main archwire first, and then precisely adjust the tooth position with double wires. And in the clinical pratice, orthodontists can choose the appropriate size of double wires according to their needs.关键词
