Influência do gel hidrossolúvel no grau de conversão de resinas impressas durante o processamento de pós cura

Abstract

The molding technique has been undergoing processes of evolution, reaching the process of 3D printing objects for dental purposes. The most commonly used printing is with photosensitive liquid resins, which go through three stages of production: printing, washing and post-curing. Due to the use of photosensitive resin, the post-curing process is of paramount importance for resin conversion. Therefore, this study evaluated the degree of conversion of the resins in the post-curing stage of the printed resins. For this we used discs printed with the long-lasting resins of Varseo Smile and Prizma Biocrown, which went through the two initial stages and in the third were divided into groups, one of the groups went through the post-cure stage with water-soluble gel and the other without the water-soluble gel. Since the data were obtained by FTIR and analyzed by ANOVA and Turkey's Post-Hoc test, we saw that the degree of conversion of the printed resin is the same in the four groups. We conclude that the use of water-soluble gel does not interfere with the degree of conversion of the printed resins.
