Experimental Study on the Mechanical Behavior of Orthodontic Arches Exposed to the Environment in the Oral Cavity.

Background: The arches used in orthodontic therapy are subject to increasing physical and chemical stresses.

Purpose Of The Study: This in vitro experimental study aims to highlight and compare the main mechanical properties of orthodontic arches.

Materials And Methods: We used 40 springs, 2 materials, 20 of Ni-Cr and 20 of Co-Cr, of different diameters, 0.
