This study was designed to investigate the retention of Zirconia ceramic crowns after thermo dynamic loading using two types of adhesive cements. Twenty intact human molars were mounted in acrylic resin blocks and prepared to receive zirconia crowns. Standardized tooth preparation was carried out by CNC milling machine to have: convergence angle of 10 degree, flat occlusal reduction and 1.2 mm deep chamfer finish line and 5 mm occluso-gingival height. Teeth were divided into two main groups according to type of the adhesive cement used. Each group was further subdivided into two subgroups according to whether or not they were subjected to thermodynamic loading (5 Specimens each). Milled crowns were cemented to the prepared teeth using either RelyX Ultimate total etch cement or Ceramir self-etch adhesive resin cement. Crowns were fabricated according to manufacturer's instructions using Ice zirconia blocks. Milling was carried out by CAD/CAM Laserdenta Milling machine
