Abstract

The invention relates to deformable, curable or film-forming support materials which contain diagnostically useful additives for locus- and substance-specific intraoral diagnostics, and processes for the preparation of images for intraoral locus- and substance-specific diagnostic purposes, in which diagnostically useful additives are applied to deformable, curable or film-forming support materials containing no diagnostically useful additives, in such a quantity that a diagnostic signal can be observed, the diagnostic result being obtained without a cultivation step.
