Resumen
El éxito de trabajos de prótesis fija, está
relacionado con diversos pasos de la técnica clínica
y de laboratorio. Uno de ellos es la etapa de
impresiones. Las impresiones deben reproducir los
detalles, volumen y tener estabilidad
tridimensional. Es un hecho que pese al avance
tecnología de materiales dentales de impresión,
todavía presentan deformación cuando no se
cumplen con algunos requisitos. El volumen
excesivo de material presenta un mayor riesgo de
deformación. Por ello las cubetas individuales nos
aportan la posibilidad de trabajar con un volumen
menor de material y mejor confinado para poder
lograr presión pareja en toda la zona de la boca a
impresionar. Las cubetas individuales se usan
para tomar las impresiones definitivas y conseguir
un buen modelo de trabajo. Se usan para cualquier
tipo de prótesis, se construyen sobre el modelo
obtenido del vaciado de la 1ª impresión. Se usa
acrílico autopolimerizable y pueden construirse
con o sin topes. Las cubetillas para tomar
impresiones a muñones nos dan las mismas
ventajas, mas la posibilidad de poder ajustarse a la
zona de terminación, con menor deformación, y
brindando protección a la impresión en el
momento del retiro de la boca, dado que este es el
momento donde se producen la mayor cantidad de
alteraciones.
The success of fixed prosthetic work is related to various steps of the clinical and laboratory technique. One of them is the stage of printing. Prints must reproduce the details, three-dimensional volume and have stability. The fact is that despite the progress of dental materials technology of printing, still have distortion when not meet some requirements. The excessive volume of material presents a higher risk of distortion. Thus the individual cells give us the opportunity to work with a smaller volume of material and better confined in order to achieve even pressure across the mouth area to impress. The trays are used to make final impressions and get a good working model. Used for any type of prosthesis, are built on the model obtained from the emptying of the 1 st printing. Selfcuring acrylic is used and can be built with or without caps. The cubetillas stumps to make prints give us the same advantages, plus the ability to adjust to the end zone with less distortion, and providing protection to the impression at the time of removal from the mouth, as this is the time where there are as many alterations
