Resumen
Uno de los principios básicos del movimiento ortodóntico es
aplicar fuerzas fisiológicamente tolerables, entre los medios
más populares que se emplean para aplicar estas fuerzas
son las cadenas elastoméricas, que se introdujeron a la
profesión en 1969, y resortes cerrados, para la distalización
de caninos en la arcada superior, pero para poder realizar
este procedimiento con cualquiera de estos dos materiales
se tiene que tener en cuenta todos los factores favorables y
desfavorables de ambos, un elastómero es un material
polimérico formado por rellenos plastificantes y aditivos que
le proporcionan dureza, durabilidad, biocompatibilidad,
bioestaticidad y flexibilidad.
Aunque también presentan grandes deformaciones con
pequeños esfuerzos, tiene una resistencia limitada y
presentan fatiga.
La fatiga de los elastómeros se manifiesta por la reducción
progresiva de sus propiedades físicas como resultado de la
propagación de fracturas durante la aplicación de una fuerza
continua. Los resortes cerrados nos proporcionan una
alternativa respecto del uso de las cadenas elastoméricas,
son menos usados que estas pero más eficientes para
liberar fuerzas de intensidad baja y continua por largo tiempo
Estos resortes de níquel titanio tienen propiedades
destacadas de súper elasticidad y memoria de forma que no
necesitan de activaciones frecuentes
One of the basic principles of orthodontic movement is physiologically tolerable apply forces, among the most popular means employed to apply these forces are the elastomeric chains, which were introduced to the profession in 1969 and closed springs for distalization of canine the upper arch, but in order to perform this procedure with any of these two materials has to take into account all factors both favorable and unfavorable, an elastomer is a polymer material consisting of plasticizers, fillers and additives that provide strength, durability, biocompatibility, biostatic and flexibility. But also have large deformations with little effort, you have limited resistance and fatigue. The fatigue of elastomers is manifested by the progressive reduction of their physical properties as a result of the propagation of fractures during the application of continuous force. The closed springs provide us an alternative to the use of elastomeric chains, are less used these but more efficient to release forces continued low intensity and long. These springsare nickel titanium super-elastic featured properties and shape memory that do not require frequent activations
