Evaluation and Comparision of Biomechanical Properties of Different Loops for En Masse Retraction of Anterior Teeth Using Finite Element Analysis: An In-Vitro Study.
Journal Title: International Journal of Dental Science and Innovative Research (IJDSIR) - Year 2019, Vol 2, Issue 2
Abstract
Background: To evaluate and compare the biomechanical properties of various retraction loops using Finite Element Method. Materials and method: Using Finite element method (Ansys V15 software) 25 loops were constructed with 0.016×0.022 inch stainless steel and 0.017×0.025 inch titanium molybdenum wire. Results: The M/F ratio produced was higher and F/D rate produced was least for Opus loop compared to Snail loop, Teardrop loop, T-loop, and Teardrop with helix loop. Conclusions: For optimum delivery of M/F ratio using snail loop must be prepared in either 0.016×0.022 SS wire with preactivation bend of 10° after D2 displacement or 0.017×0.025 TMA wire with preactivation bend of 10° and 20° after D1 displacement.
