Objectives: This study investigated the mechanical properties of laminate veneers to determine their resistance to the shear force of three different types of cement used in the restorations. Materials and Methods: Laminate veneers were prepared using standard tooth preparation methods for 30 extracted maxillary central incisors. To standardize the depth, guide burs were used to prepare a depth of 0.5 mm from the buccal angle. The samples were allocated into three randomized groups (n = 10): Group A (resin using the total etch method and Variolink Esthetic DC resin cement), Group B (resin using the PANAVIA F2.0 self-etch method), and Group C (self-adhesion bonded with Rely X U200 resin cement). The prepared specimens were stored in distilled water for one week before being thermal cycled for 500 cycles in 5°C and 55°C water. A shear test was used to determine the resistance of the veneers to the bonding. The obtained data were evaluated statistically. Results: The values of the shear bond strength were statistically significant depending on the type of resin cement used (p < 0.05). The specimens that were cemented using the total-etch method had the lowest shear force value (18.79 ± 4.48 MPa). The obtained data were statistically evaluated using the Tukey multiple comparison test (p > 0.05). Conclusions: The type of cement is a highly effective factor in the bonding between fixed prosthetic restorations and the abutment tooth, and the cement used must have sufficient resistance to shear forces
