Comparison of frictional forces during the closure of extraction spaces in passive self-ligatingbrackets and conventionally ligated brackets using the finite element method
Autores: Gómez-Gómez SL, Sánchez-Obando N, Álvarez-Castrillón MA, Montoya-Goez Y, Ardila CM Abstract Background: This study compared the frictional force resulting from the bracket/archwire interface and the stress at the root/periodontal ligament/bone interface, between passive self-ligating brackets and conventionally ligated brackets, during the space closure stage. Materials and methods: A…
