Aim:To evaluate fracture resistance and survival rate of IPS Empress CAD versusglazedCeltra Duo ceramic laminate veneers.Methodology:Thirty-six ceramic laminate veneers were fabricated for maxillaryanterior teeth. The patients were divided into two groups according to the materialGroup 1(control group) fabricated from IPS Empress CAD laminate veneers and group2(intervention group) fabricated from glazedCeltra Duo laminate veneers.Standardized the same preparation with butt joint design and chamfer finish linelocated supra gingival were performed for all the teeth.The fabrication of the veneers was performed using Cad\Cam(Ceramill motion)machine, with software (Exocad). The veneers surfaces were treated and silanatedaccording to the manufacture instruction of each ceramic and enamel surfaces wereetched where total etch adhesive protocol was obeyed using BISCO.Fracture resistance, marginal adaptation, retention, and sensitivity for both groupswere evaluated according to United States public health services (USPHS) criteria. Results:Fracture resistance, marginal adaptation, retention, caries and sensitivitywere evaluated according to the criteria of USPHS and we found there is nosignificant difference as both groups scaled zero score. Conclusions:Both IPS Empress Cad and glazedCeltra Duo laminate veneers revealed high successful clinical performance in terms of fracture resistance, marginal adaptation, retention, and sensitivity
