Abstract

The fracture resistance of Computer-Aided Design/Computer-Aided Manufacturing (CAD-CAM)-fabricated porcelain-fused-to-metal (PFM) and all-ceramic (monolithic zirconia) endocrowns in cariously extracted mandibular premolars and molars. Sixty root canal-treated teeth were restored and tested using standardized protocols. Fracture resistance was measured with a Universal Testing Machine. Results showed significantly higher resistance in zirconia endocrowns across all tooth types. Thus, we show the use of zirconia as a more durable restorative material for posterior teeth with structural compromise.
