Abstract
El objetivo del presente estudio fue comparar el efecto in vitro de las técnicas de impresión y el tiempo de vaciado en la exactitud dimensional de dos siliconas de condensación. El diseño del estudio fue experimental, comparativo y longitudinal. Se realizó un patrón de acero metálico, la muestra consistió en 60 impresiones, se clasificaron en 5 grupos, dependiendo del tiempo previsto para el vaciado, siendo 30 minutos, 3, 12, 24, 48 horas. se midieron su diámetro, distancia y su altura, utilizando un vernier milimétrico digital. Los resultados mostraron que las dos siliconas tienen la misma estabilidad dimensional en el tiempo, utilizando la técnica de impresión de una mezcla y dos mezclas, concluyéndose que no hubo diferencias estadísticamente significativas entre los grupos de estudio

The results showed that the two silicones have the same dimensional stability over time, using the printing technique of one mixture and two mixtures, concluding that there were no statistically significant differences between the study groups
