Comparison of sliding mechanics and loop mechanics in orthodontic tooth movement: A three dimensional finite element study

摘要

This study was conducted using 3-dimensional Finite Element Analysis to evaluate the stress related changes in the periodontal ligament. The objectives of the study were to determine the optimum orthodontic force for both sliding and loop mechanics and to determine efficacy of two loop designs namely T - loop and Tear Drop loop. The efficacy of Permachrome and Beta III titanium archwire in loop mechanics were also evaluated.
