<p>A dental colour mixture indicator device is described. In an embodiment, the dental colour mixture indicator device (420) comprises four component indicator devices (400-403) each retained by a common base (410). Each component indicator device (400-403) has an array of colour samples (Y1-2, C1-3, R1-2) mounted to individual blades (430, 440-442, 450-452, 460-462), with each group of blades able to be plucked from the base (410) for the purposes of a comparison with a tooth. Each colour sample (Y1-2, C1-3, R1-2) corresponds with an artificial tooth material, and, on the basis of the comparison, a mixture of the respective tooth materials allows correct colour matching of a restorative tooth. The arrayed colour samples (Y1-2, C1-3, R1-2), coincide with a corresponding location on a colour co-ordinate system. The central colours (201) of each component indicator device (400-403) are offset from other ones of central colours with respect to the colour co-ordinate system. This means a fewer number of samples are required than in the prior art to encompass the whole body of tooth colour. <IMAGE></p> |
