Dissertation note: Thesis (M.Sc.) - Cairo University - Faculty of Oral and Dental Medicine - Department of Prosthodontics Summary: The purpose of the present study was to investigate fracture resistance, marginal accuracy and mode of fracture of the CAD / CAM translucent zirconia three unit posterior bridges. The number of models used for this study were 20. All 20 models were constructed into a three unit FPD bridge with full coverage retainers on both abutments, restoring the maxillary second permanent premolar. The constructed 20 models, were divided prior to construction into two different groups, according to the material used in model construction. Each of the studied groups consisted of 10 models. The first group of FPDs was constructed using veneered zirconia cores. The second group of FPDs was constructed using Zirconia full anatomical bridge. The bridges were made using the cerec in Lab 3.88 CAD/CAM system, which is one of the best systems used in FPD construction owed to its highly accurate scanning, design and milling.Marginal accuracy, fracture resistance and mode of fracture were determined for the bridge models. Marginal accuracy was conducted using digital optical microscopy, while fracture resistance of the FPDs was tested using an electronic compressive strength measuring machine followed by SEM scanning to assess the effect of mode of fracture
