Unica anterior is the ideal matrix system for anterior restorations such as class III, IV, V, direct stratifcation composite veneers and shape modifications. Thanks to their contoured shape, the matrices of the system, Unica anterior adapt correctly to the different morphologies of all anterior teeth. They allow the proximal and cervical margins to be restored at the same time, even in the presence of a rubber dam or gingival retraction cords, thus reducing the time needed for restoration. In addition, once the Unica matrices are positioned, they allows to visualise the final shape of the restoration.
