Advancements in dental research due to the high demands in esthetic dentistry lead to the creation of all ceramic restorations to exactly mimic the appearance of natural teeth and eliminate the need of metal substructures.In todays industry full-contour monolithic restorations provide exceptional esthetics without requiring a veneering ceramic and its requisite bond interface, therefore increasing the structural integrity of such restorations. However,concerns about the effect of porcelain as it causes accelerated wear of the opposing enamel is one of the major drawbacks associated with dental ceramics. Wear is an inevitable process and the wear that occurs between dental enamel and restorations is a very important factor that has to be considered in the selection of restorative materials in the clinical practice. Therefore, this study was done to compare the wear behavior of monolithic zirconia against natural teeth to lithium disilicate based ceramics and nano-flourapatite veneering glass ceramics with different finishing procedure; polishing and glazing
