Brief Summary
Despite of the improved esthetics of ultra-translucent zirconia, bonding between resin cement and zirconia is difficult to achieve because of their chemical inertness and lack of silica content. However, the effect of the bond strength with the new generation of high-translucent zirconia materials is not clear and further studies are needed. Kongkiatkamon, Suchada et al., (2023) The long-term bond strength of cubic zirconia was similar to 3Y-TZP zirconia and lithium disilicate ceramics and showed sufficient bond strength. A 5-mol% yttria-stabilized tetragonal Zr polycrystal showed high shear bond strength similar to Li disilicate glass-ceramic. Air blasting of Zr followed by primers and resin cements based on 10-MDP monomer has proven its efficiency in Zr-resin bonding. Both ultra-translucent 5Y-PSZ Zr and Li disilicate offer viable options for esthetic restorations on anterior teeth Adak et al. (2023),Elsisi et al. (2024) Currently, there is a lack of reports in the literature regarding the long-term clinical performance of ultra-translucent zirconia, especially considering its use in manufacturing monolithic veneers. Therefore, the purpose of the present clinical trial is to assess the validity of using ultra-translucent multi-layer zirconia ceramic veneer as an alternative to lithium disilicate ceramic veneer
