Specimens were divided into nine different groups, subject to post-polymerization conditions at three different times (15, 20, and 30 min) and three different temperatures (40, 60, and 80 degrees C) (n = 10). Color and surface roughness measurements were repeated pre-post thermal aging (5.000 cycles, 5-55 degrees C) and a flexural strength test was carried out. Data were analyzed with Shapiro-Wilk, Kruskal-Wallis, ANOVA, Tukey HSD, and Dunn tests (alpha < 0.05).Results: Delta E-00 values showed results below the acceptable color threshold, except for the 30 min 40 degrees C group (Delta E-00 <1.8). No difference was found between the relative translucency parameter and surface roughness values of the 20 min 60 degrees C group recommended by the manufacturer and the other groups. A significant difference was found between the flexural strength values of the groups (p < 0.001).Conclusions: The color properties, surface topography, and mechanical properties of the printed permanent crown material were affected by different post-polymerization conditions: polymerized at different times and temperatures. Although the flexural strength and color change values showed promising results, more studies are required to evaluate its suitability for clinical use.eninfo:eu-repo/semantics/closedAccessdental materialsin vitro testpermanentthree-dimensional printingArticle10.1111/jopr.138182-s2.0-8518214184638102064Q1WOS:001141679400001Q1
