Samples were evaluated and compared by tensile tests on the Shimadzu® AG-IS universal mechanical testing machine. It was possible to establish that GUMMETAL® has a much higher elastic limit; with regard to the force, it was possible to determine that GUMMETAL® shows a lower and constant force; with the variable 'stiffness' CuNiTi showed a low but less stable stiffness, while GUMMETAL® on the contrary showed a higher stiffness but at the same time more constant; CuNiTi showed a much higher but more unstable range, and GUMMETAL® showed a much smaller but more stable range.Se realizó con 60 muestras de alambre ortodóntico 0.017x 0.025 pulgadas; 30 correspondían a la aleación GUMMETAL® y 30 a CuNiTi termoactivado para analizar y comparar las variables mediante ensayos de Carga-Deflexión y Tensión-Esfuerzo, en la máquina universal de ensayos mecánicos Shimadzu AG-IS. Se estableció que el GUMMETAL® presenta un límite elástico mucho mayor; el GUMMETAL® muestra una fuerza más baja y constante; el CuNiTi mostro una rigidez baja pero menos estable, el GUMMETAL® por el contrario mostró una rigidez más alta y estable; el CuNiTi mostró un rango mucho mayor aunque más inestable y el GUMMETAL® mostró un rango mucho menor pero más estable. Conclusiones: el CuNiTi presentó valores más altos en 3 de las 4 variables evaluadas pero es más inestable que el GUMMETAL®, siendo este último más constante en la entrega de fuerzas menores y lo hace ideal para las primeras etapas de tratamiento de ortodoncia.spaAcceso abiertoComparaciónPropiedades Mecánicas,Carga,Deflexión,Alambres de Ortodoncia610Trabajo de grado (Pregrado y/o Especialización)Comparison,Mechanical Propertis,Load,Deflection,Orthodontic Wiresinfo:eu-repo/semantics/openAccesshttp://purl.org/coar/access_right/c_abf2Arango Santander, S., y Ramírez Vega, C.
