| Aim: This study evaluates the surface roughness and wear resistance of two types of 3D-printed permanent materials and CAD/CAM milled material. Materials and Methods: A total of 120 rectangular-shaped samples were fabricated from 3D-printed hybrid materials (Crowntec and VarseoSmile) and one CAD/CAM milled hybrid material (Vita Enamic). 90 samples (14×12×5 mm) were used for the surface roughness test, and the roughness measurements were performed at the baseline and after storage in different staining solutions for 1 week using a 2D profilometer while 30 samples (14×12×5 mm) were used for wear test and the real weight of each sample was measured at the baseline and after subjecting to wear using (MT 4003, TRIBOMETER, USA) wear device. The data were subjected to statistical analysis using a two-way analysis of variance (ANOVA) and post-hoc least significant difference (LSD) tests with a significance level of 0.05. Results: Crowntec exhibited a statistically higher surface roughness value compared to both VarseoSmile and Vita Enamic, however, VarseoSmile showed statistically greater roughness compared to Vita Enamic. Regarding the wear test, the results showed a significant difference in weight loss between 3D printed and Vita Enamic materials(P<0.05) with no statistical difference between Crowntec and VarseoSmile. The lowest weight loss was observed in Vita Enamic (1.56 ± .08) and the highest weight loss in VarseoSmile (2.3± .08). Conclusion: 3D printed material exhibits a rougher surface and higher wear when compared to milled material. | ||
