    Author(s): Ibtehal M Hussien*, Adel F Ibraheem

    Objectives: The main objective was to investigate the effect of marginal cement space thickness on the fracture strength of full contour monolithic zirconia crowns using different luting agents. Materials and methods: 48 sound human upper first premolar teeth were selected and prepared following the guidelines recommended for KATANATM zirconia. The prepared teeth were divided according to thickness of cement space around the margin into two main classes (n=24) as follow: (Class I: 0 μm) and (Class II: 25μm), additional cement space of 80 μm starting 1mm above the finish lines of the teeth. Every class was subdivided into three subclasses according to the type of luting material(n=8): subclasses(AI,AII) cemented with RelyX™ Ultimate adhesive luting agent, subclasses(BI,BII) cemented with RelyX™ Unicem 200 self-adhesive luting agent and subclasses(CI,CII) cemented w..
