Title: METHOD FOR DEFINING THE COLOUR OF A MATERIAL OF A DENTAL RESTORATION
Abstract:
The invention relates to a computer program for defining the colour of a material of a dental restoration, in which the desired tooth colour is entered by the user as the target tooth colour (56), which is the colour of a neighbouring tooth, and in which, during the defining of the colour of the material of the dental restoration on the basis of the target tooth colour (56), the colour of the material of the dental restoration material is modified on the basis of parameters such as the colour of a stump and/or an abutment, the layer thickness of the dental restoration, the type of dental restoration and the machining technique. The defining of the colour of the material of the dental restoration is controlled by the computer program, and as soon as a parameter is selected, the next parameter is automatically offered, the selection being limited based on related parameters such as layer thickness, type of restoration as well as the indication and the material.
