El uso de restauraciones provisionales sigue siendo una gran herramienta para determinar la efectividad terapéutica de las rehabilitaciones en la cavidad oral. En este sentido, el desarrollo de la impresión 3D nos permite su realización de manera rápida con un bajo coste. Además, el estudio del color de las restauraciones es de vital importancia en nuestra práctica diaria debido a la demanda de estética actual. Por lo tanto, el presente estudio se pretende evaluar la estabilidad del color de las restauraciones impresas con esta tecnología para valorar esta opción como alternativa de tratamiento.
Purpose: The aim of this in vitro study was to assess color stability of 3D printed temporary restorations after post-curing and aging processes.Material and Methods: Thirty interim restorations (n=30) were fabricated by using digital light processing (DLP) 3D printer. Fifteen of them (Group 1) were subjected to extra post-curing proceeding (19 minutes and 30ºC) and the other fifteen (Group 2) were subjected to aging process using artificial saliva (2000 cycles). Color measurements in the CIELAB coordinates were made by using a VITA Easyshade Compact spectrophotometer. Color differences (ΔE) values were calculated by using the CIE76 formula. Results: Significant statistically differences were found between a* and b* values in Group 1. In group 3, differences were found only in a* value. Besides, there were differences in ΔE values between groups, being statistically significant. Conclusion: With the limitations of this study, statistically differences were found between the values in both groups. Nevertheless, further studies are required to confirm this affirmation
