Aim: Compared to conventional materials, polymer/ceramic hybrid composites have the potential to tailor the desirable properties that individual component can offer. The aim of this study is to evaluate the fracture resistance of crown restorations fabricated from different hybrid ceramic materials in CAD\CAM system. Materials and Methods: 45 extracted molar teeth were divided into 3 groups randomly, each group containing 15 specimens. All teeth were placed in autopolymerizing acrylic resin blocks and they were prepared according to standard tooth preparation procedures with a chamfer finish line. Digital impressions were taken with CAD/CAM system (CEREC Omnicam System, Salzburg, Österreich). After scanning crown restorations were fabricated from 3 different CAD/CAM blocks (IPS e.max CAD, Vita Enamic, and GC Cerasmart). After cementation of the restorations, fracture resistance was measured with a universal testing machine (Shimadzu product, Kyoto 604-8511, Japan). After collecting the data, the results were evaluated statistically. Results: Analysis of the results showed statistically significant difference between all the groups (P<0.05). CeraSmart group exhibited the highest mean fracture load mean (3135.74±860.91) compared to E-max (2614.47±578.79) and VitaEnamic groups (1687.90±570.91). Analysis of the results showed that Cerasmart and E-max groups had statistically similar fracture loads and higher than Vita group. Conclusion: Hybrid materials fabricated with CAD\CAM system showed excellent fracture resistance.
