Case Description: The veneers placed in this case gave the patient a more youthful smile. 

A digital smile design was performed to decide the correct anterior tooth proportions, which included tooth Nos. 12 to. 22. Once the wax-up was complete, a silicone matrix was fabricated for the mock-up technique. The mock-up was done with bisacrylic material.   Once the patient approved the mock-up, the preparations were performed, followed by double silicone impression and cementations. This was done according to BISCO instructions, which call for using rubber dam isolation to avoid contamination, allow for a clean restorative environment, correct visualization of the gingival margin during adjustment of the veneer restorations, and to facilitate the removal of excess cement
After the veneers were cemented, the final result was a beautiful and more youthful smile. The patient confirmed her satisfaction with the smile enhancement after the procedure and during the six-month follow-up consultation.
