The invention relates to a method for producing an artificial tooth,
comprising a base layer substantially determining strength and at least
one cover layer substantially determining appearance of a finished
artificial tooth, said method comprising: establishing the available
outer shape and dimensions for the finished artificial tooth, e.g. with a
CAD-CAM system; acquiring an image of a natural tooth to be replaced by
the artificial tooth or a corresponding natural tooth over at least the
in use visible outer surface thereof, including variations in appearance
in said outer surface; determining in the appearance determining
properties of the cover layer to correspond with the variations in the
appearance of the natural tooth to be replaced or the corresponding
natural tooth, and determining a thickness of the cover layer locally
required for said correspondence; constructing the base layer to a shape
and dimensions, which are based on the shape and dimensions available for
the artificial tooth and prior to construction deducting, in the CAD-CAM
system therefrom the locally required thickness of the cover layer; and
applying the cover layer over the base layer to attain the available
outer shape and dimensions for the finished artificial tooth.
