the aim of this study was to evaluate the clinical performance of two CAD/CAM materials, hybrid nano-ceramic and lithium disilicate ceramic, in the fabrication of anterior endocrowns in patients with anterior endodontically treated teeth. While the postulated null hypothesis of this study was that there will be no significant difference between the performance of hybrid nanoceramic and lithium disilicate anterior endocrowns in patients with endodontically treated teeth.
