“…The results were attributed to E.max high crystalline content and its homogeneity. This finding comes in accordance to the study of Stawarczyk et al 2020 [20] who discussed four point flexural strength of lithium silicate ceramics. Emax press showed the highest values followed by livento press and Celtra press.…”

“…All material groups were fired after surface finishing according to their respective manufacturer's instructions to improve their mechanical properties (9,10,12) . Belli et al reported that the Young modulus of both lithium disilicate (IPS E-max CAD) and ZLS (Celtra) materials were similar regardless of the differences in their composition and microstructure (31) .…”

“…These monolithic glass ceramics can be fabricated either by CAD/CAM technology or by heat pressing technique. Lithium disilicate ceramics contain about 70% platelet-shaped lithium disilicates which are crystallized in the glass phase (9) . IPS E max CAD (Ivoclar Vivadent, Schaan, Lichtenstein) is a lithium disilicate glass ceramic designed for CAD/ CAM which combines good esthetics, high flexural strength, and fracture toughness (10) .…”

Aim:The purpose of this in vitro study was to evaluate the wear resistance and surface roughness of zirconia reinforced lithium silicate glass-ceramic (ZLS) compared to lithium disilicate glass-ceramic after simulated mastication.Materials and Methods: Thirty samples were prepared and divided according to the material of construction into three groups (n = 10). Group ( 1): E Max-CAD, Group (2): Celtra Duo ZLS, Group (3): Celtra Press ZLS. The sectioned samples of E-max CAD (Ivoclar, Vivadent, Schaan, Liechtenstein) blocks were polished and crystalized. The sectioned samples of Celtra Duo ZLS (Dentsply Sirona) blocks were glazed and fired. The Ingots of Celtra Press (Dentsply Sirona) were lab pressed, sectioned, glazed and power fired. The two-body wear testing was done using a chewing simulator integrated with thermo-cycling. Each ceramic sample was weighed and evaluated for surface roughness before and after the wear simulation test using an electronic analytical balance and optical profilometry, respectively.Results: IPS E-max CAD revealed the highest amount of weight loss with no statistically significant difference between groups as indicated by ANOVA test. The change in weight for each group was non-significant as demonstrated by paired t-test. The roughness mean value for E-max CAD was significantly decreased and recorded the lowest roughness change. Tukey's post-hoc showed a non-significant difference in the roughness mean value between Celtra Duo and Celtra Press. The roughness change for either Celtra Duo or Celtra Press groups was non-significantly increased as demonstrated by paired t-test.Conclusions: ZLS Celtra ceramics had insignificant less wear and significantly higher surface roughness with enamel antagonist compared to E-max CAD. Although wear and roughness were affected by the surface finishing of glass ceramics, the construction method of ZLS restorative materials had no significant impact on both.

“…Though, the manufacturer recommended finishing the restoration by special power firing step which increases ceramic strength to about 500 MPa. (14) With regard to the optical properties, ZLS materials have been improved in translucency, fluorescence and opalescence which provide a natural appearance and the desired esthetics. (10) For both the celtra duo and the celtra press, different shades and degrees of translucency are available to match each clinical case.…”
