El objetivo general de esta memoria es estudiar el comportamiento superel´astico de la aleaci´on Cu-11.8 %pAl-0.5 %pBe, bajo distintas condiciones de temperatura, microestructura, amplitud y frecuencia de oscilaci´on, ...

The purpose of this study was to evaluate and to compare the thermomechanical properties of three distinct rectangular orthodontic NiTi wires by means of structural caracterization, torsion and tensile tests. In addition, ...

Excessive loads over dental implants can cause marginal crest decrease through bone reabsoption or collapse of the components of the bone-implant system. The transmission reduction of the masticatory impacts to the bone ...

During clinical routine, the orthodontist uses several materials, which include metallic alloys in the form of metallic wires. However, it is necessary that the professional has some knowledge of the properties of those ...

La aleación de níquel titanio fue descubierta por el ingeniero metalúrgico William Buehler en el año de 1963 en la Base Naval Ordnance Laboratory en Maryland, Estados Unidos. La denominó NITINOL por los elementos de la ...

The aim of this study was to evaluate and compare the mechanical and structural properties of three different brands of NiTi orthodontic wires. The sample comprised of three superelastic (SE) and three thermoactivated (TA) ...

The effect of cyclic rotary bending strains on martensitic and reverse transformation temperatures, on mechanical properties and on recovery strain capacity, was investigated in this work, using wires of a superelastic ...

The continuous growth of the use of superelastic alloys, especially those of the Ni-Ti system, in medical and odontologic applications, together with the growing trend to less invasive procedures, have imposed an ever ...
