Multichroma format must not be mistaken with the multilayer format.
Multichroma format is a new concept created by Graphenano Dental in which the transmission of background colours of dental restorations is simplified with the intention of achieving the naturalness of the restorations, imitating optical effects of natural teeth.
The regular version that the sector offers is a multilayer format of horizontal setup. This format generates “band effects” of transition between layers, which worsen in situations of non-harmonic anterior groups and in speed curves of posterior sectors. By contrast, the configuration of natural structures is vertical, so the depth and thicknesses create multichromatic light effects. In other words, the solution offered by dental sector is a horizontal colours configuration, while the nature of the tooth is vertical.
As it would be very difficult to obtain an arrangement of vertical layers in a disc format for multiple unit restorations, Graphenano Dental achieves these natural effects through the control of thicknesses with single-layer translucent colours. When the tooth is out of the mouth, the most translucent area is the cervical edge (Image 1); but, when the tooth is adapted onto the model, the chroma is enhanced in the cervical area and the most translucent area is now the incisal edge, in the same way as in a natural setup (Image 2).
