ABSTRACT

In recent years new ceramic materials and new technologies have been developed, for more-and-more popular integral-ceramic dental restorations. Clinical decision on which material, design, technology is more suited for patient becomes harder, with every new introduced material and technique. Ceramic materials are known to be brittle, prone to fracture materials, when they are used to restore posterior teeth. The aim of this study was to determine fracture resistance of different integral ceramic crowns: hot-pressed ceramic and bilayered all-ceramic crowns with different core designs. Monolithic hot-pressed ceramic crowns show lowest stress resistance than bilayered zirconia-hot-pressed ceramic with anatomic core design. Within the limitations of this study can concluded that most indicated restorations for posterior area are bilayer crowns with anatomic framework design, and uniform thickness porcelain veneer.
