Resumo: |
The objective of this study was to evaluate the surface topography of the aesthetic yarn before and after the deflection test. The sample consisted of 70 round 0.014h test leads, 10 of each of the evaluated brands: Orthocosmetic Elastinol (Masel), Flexy Super Elastic Esthetic (Orthometric), InVu (TP Orthodontics) and ProForm Nitanium (Ortho Organizers ). Teflon® coated NiTi wires; Optis (TP Orthodontics). Fiberglass-reinforced resin wire or FRP; Niticosmetic (Tecnident). NiTi yarn coated with epoxy resin; And Nitinol SE (3M Unitek). Superelastic NiTi wire, used for control. The surface topography of each wire was evaluated by a rugosimetre and by an optical microscope, before and after being subjected to a deflection test, on the side where the force was applied and on the opposite side. Each wire was deflected in 3.1mm, at a speed of 1mm / min, with a load cell of 5N at 36.C + 1.C. The analysis of variance at three criteria (p <0.05) showed significant difference between the strands and the Tukey test showed that the Optis (TP Orthodontics) wire presented increase in the roughness parameters Ra, Rt and Rz, after the deflection. |
