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.
MATERIAL and METHODS: Laminate veneers were prepared using the 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 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 that was applied (p ˂ 0.05). The specimens that were cemented using the total-etch method (18.79±4.48 MPa) had the lowest shear force value. The obtained data were evaluated statistically by Tukey multiple comparison test (p > 0.05).
CONCLUSIONS: The 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.
