dc.description.abstractObjective: Compare in vitro the dimensional precision of the polivinil siloxano using the technique of impression of double mixture; double impression with margin relief and double impression with total relief. Materials and methods: The samples were composed of 42 impressions using Putty-Spedeex polivinil siloxano from a master stainless steel model, which presented two homogeneous pillars that simulated the preparation for a crown. These samples were divided into 3 groups according to the printing technique (double mix, double impression with margin relief and double impression with total relief). In order to determine the dimensional accuracy of the final models in comparison to the master model, 7 measurements (MD1, MD2, VL1, VL2, AL1, AL2, DI) were performed with a coordinated machine, Contura G2 model with contact scanning technology ZEISS. Statistical tests were performed Kruskal-Wallis and U of Mann-Whitney. Results: Statistically significant differences (p˂0.001) were found in measures MD1, MD2, AL2 when comparing the three printing techniques with the master model. The double impression technique with total relief presented a greater number of measures (MD1, MD2, VL1, AL1, DI) than did not show statistically significant differences (p <0.005) in comparison to the master model. Conclusions: The technique of double impression with total relief presented greater dimensional accuracy than the techniques of double mixing and the technique of double impression with relief of the margin using silicone of condensation.

html.description.abstractObjetivo: Comparar in vitro la precisión dimensional de la silicona por condensación mediante la técnica de impresión de doble mezcla; de doble impresión con alivio del margen y doble impresión con alivio total. Materiales y métodos: Las muestras estuvieron conformadas por 42 impresiones utilizando silicona por condensación Putty- Spedeex de un modelo maestro de acero inoxidable, el cual presentó dos pilares homogéneos que simularon la preparación para una corona. Estas muestras se dividieron en 3 grupos según la técnica de impresión (doble mezcla, doble impresión con alivio del margen y doble impresión con alivio total). Para determinar la precisión dimensional de los modelos definitivos en comparación al modelo maestro, se realizaron 7 mediciones (MD1, MD2, VL1, VL2, AL1, AL2, DI) con una máquina especializada en coordenadas, modelo Contura G2 con tecnología de Scanning por contacto ZEISS. Se realizaron las pruebas estadísticas Kruskal-Wallis y U de Mann-Whitney. Resultados: Se encontraron diferencias estadísticamente significativas (p˂0.001) en las medidas MD1, MD2, AL2 al comparar las 3 técnicas de impresión con el modelo maestro. La técnica de doble impresión con alivio total presentó una mayor cantidad de medidas (MD1, MD2, VL1, AL1, DI) que no mostraron diferencias estadísticamente significativas (p<0.005) en comparación al modelo maestro. Conclusiones: La técnica de doble impresión con alivio total presentó mayor precisión dimensional que las técnicas de doble mezcla y la técnica de doble impresión con alivio del margen utilizando silicona de condensación.
