Innovative sectional matrix developed in collaboration with specialist dentists from all over the world. Thanks to the matte blue surface, the matrix is ??poorly reflective and has no blinding effect. Contrast between the dark colour and the white teeth, allowing identification the area of ??intervention with greater precision. Colouring of the matrix does not detach and the particles do not disperse inside the cavity or the filling material. High-quality steel optimises restorative procedures as the matrix does not yield within the cavity, nor can it be deformed by interdental wedges . Indispensable when using modern technologies that involve the use of intense light sources, such as monocular lenses and dental microscopes.
