Özet:

 Objective:. This in-vitro study aimed to evaluate the surface roughness Ra and color stability of novel monolithic CAD-CAM materials after thermomechanical aging. Methods: Forty specimens were obtained from 4 different materials a resilient ceramic C, ceramic-reinforced PEEK BH, lithium disilicate glass ceramic EX, and a resin based composites B n10. Initial Ra and color coordinates were recorded. All specimens were than subjected to thermomechanical aging. Ra and color coordinate measurements were repeated. CIEDE2000 formula was used to calculate the color changes ΔE00. Kruskal-Wallis and Dunn tests were used to analyze data, while the effect of aging on Ra was analyzed with Wilcoxon test α.05. Results: Regardless of aging, BH showed higher Ra than EX P.001, whereas the differences between BH and the other materials were nonsignificant P.202. Thermomechanical aging led to higher Ra for all materials tested P.005. The greatest ΔE00 was observed in BH P.002, while the difference among the other materials was nonsignificant P.05. Ra of ceramic-reinforced PEEK was above clinical threshold, regardless of thermomechanical aging. Conclusion: Thermomechanical aging caused a color change that was perceptible for all the materials tested, while it was also unacceptable for ceramic-reinforced PEEK.
