Ideal matrix system for anterior restorations, such as Class III, IV, V, composite veneers with direct stratification, and shape modification. Thanks to their shape, the matrices of the Unica anterior and Unica minideep anterior system correctly adapt to the different morphologies of all anterior teeth. They allow for simultaneous restoration of the proximal and cervical margins, even in the presence of a rubber dam or gingival retraction cords, thus shortening the time required for restoration. Additionally, once the Unica matrices are in place, they allow visualization of the final shape of the restoration even before starting the procedure.
