Abstract
The present invention suggests an apparatus for simulating the ambient color and translucence conditions present in the oral cavity of a patient for the purpose of checking the color stimulus specification of dentures prior to their implanting into the oral cavity of a patient. The apparatus comprises an artificial jaw portion including a dimensionally stable, elastic artificial gum body portion simulating at least the vestibulary gum of a patient in which the teeth are inserted. The artificial gum body portion is made of a translucent material. The teeth can be individually replaced by dentures. The color stimulus specification of a denture inserted into the apparatus is checked by means of a color stimulus specification measuring apparatus and compared to the values obtained from a measurement taken in the oral cavity of a patient.
