    The Effect of Different Cement Space Thickness on Fracture Strength of CAD/ CAM all Ceramic Crown Restorations
    Author(s): Mohammed T Mohammed and Adel F Ibraheem*

    Objectives: The purpose of this in vitro study was to evaluate the effect of variable cement space thickness on the fracture strength of CAD/CAM all ceramic crown restorations. Materials and method: 16 sound human maxillary first permanent premolar teeth of comparable size and shape extracted for orthodontic purposes were collected and selected to be used in this in vitro study. All the dimensions of each crown were tested with using one-way ANOVA in order to reduce the confounding variables. The teeth samples were divided into two main groups according to the different cement space parameter setting (n=8). Group A: 0 cement space around the margin and additional cement space of 100 Mm starting 1mm above the finish lines of the teeth. Group B: 0mm cement space around the margin and additional cement space of 120 Mm starting 1mm above the fin.. Read More»
