Abstract
A blank for producing dental prostheses by particularly material-removing processing comprises a tooth element and a jaw element. These elements are preferably differently colored layers of a blank produced from the same material. In order to cover a dividing line between the differently colored regions, a gum element is arranged especially in a recess of the finished dental prosthesis.
