    Aim: The objective of this study done in vitro was to compare and assess the effects of various marginal cement gap thicknesses on retention of zirconium with using various luting agents. Materials and Method: A 48 freshly first premolar teeth of comparable shape and size. Teeth were prepared by one operator with the aid of modified dental surveyor to receive a monolithic zirconia crown restoration according to the guidelines recommended for KATANATM zirconia. The prepared teeth then based on the setting of marginal cement space thickness, they were separated into two main groups (n=24), Group Aa: zero μm cement space around the margin, Group : 25μm cement space around the margin and additional space 80 μm starting 1 mm above the margin for both groups. Each group then divided into 3 subgroup (N=8) according to luting used: (A1, B1) using RelyX U200 self-adhesive cement ,(A2,.. Read More»
