Comparative Evaluation of Bond Strength of CAD/CAM Monolithic Zirconia Copings Influenced by Luting Agents and Finish Line Design.

Aim: The aim of the study was to comparatively evaluate the bond strength of CAD/CAM monolithic zirconia copings using three luting agents and two different finish lines.

Materials And Methods: For the evaluation of bond strength, 60 extracted human maxillary first premolars were prepared to receive CAD/CAM monolithic zirconia copings. They were randomly divided into six groups of 10 samples each to receive CAD/CAM monolithic zirconia copings to bond with three different luting agents on two different finish lines.
