Document Type and Number:
Japanese Patent JPH03504126
Kind Code:
A
Abstract:
A composite material kit for dental fillings, comprises a base composite material, the three-dimensional colour value of which, expressed as hue, chroma and blackness/whiteness, so corresponds to that of an average selection of natural teeth that the visual impression of tooth and filling will be the same, and at least three further composite materials, the three-dimensional colour values of which deviate in different directions from the colour value of the base composite material in such a way that adequate coverage is obtained of the colour value dispersion of natural teeth. When using the composite material kit, the colour is matched by selecting one of the four and preferably five composite materials, of which the base composite material is one and the other composite materials have colour values deviating from the colour value of the base composite material towards whiter, blacker and more coloured with higher blackness or, in the preferred case, more yellowish and more coloured with higher blackness, respectively. the colour can also be matched by selecting the thickness of an outer layer (5) of the filling, the composite material of the inner layer (4) being selected among any of the remaining composite materials, and the outer layer being formed of the base composite material which, in this case, has a lower opacity than the remaining composite materials, and/or a transparent composite material.
