Elsaka SE - This study involved assessment of the optical and mechanical properties of newly introduced monolithic multilayer zirconia with two types of monolithic zirconia. The researcher found that optical and mechanical properties of the tested monolithic zirconia were material dependent. It was also noted that compared with partially stabilized zirconia (ZT), fully stabilized monolithic zirconia materials (Ceramill Zolid FX Multilayer and Prettau Anterior) were relatively more translucent.
