N2  - Objectives: The aim of the study was to develop a predictable controlled  method for the precipitation of nano-alumina coating as a surface treatment in trial to improve zirconia /resin bonding and to determine the  durability of bond between coated samples and commercially available  resin cement. Conclusions. The deposition method of nano-alumina is a promising, yet  complex method to be used on zirconia substrate according to both  mechanisms. Meticulous selection of alumina precursors, pH, temperature and  stirring time as crucial and sensitive parameters in co-precipitation  of alumina on zirconia substrates. Aluminum nitride is a more suitable precursor for nano-alumina  deposition from suspension on zirconia substrate.The use of sulfuric acid as an innovative surface pre-coating  method to the zirconia indicates its direct beneficial influence on  surface roughness and bond strength of zirconia substrates with  adhesive cement resin.Control polished specimens had a negative influence on strength  showing the lowest shear bond strength values to adhesive resin  cement of all subgroups
