Abstract
A method for producing a blank for a permanent dental crown starts with a blank that includes a tooth module and a support. A preparation is formed on the underside and serves for connection to an anchoring element such as a screw element or tooth stump. The tooth module and the support are produced from the same material in a first process that permits a high surface quality. In a second process, the tooth module and support are connected to one another and can then be further processed. This method leads to a high dimensional stability of the resulting crown and permits the use of inexpensive plastic material for a high-quality permanent dental prosthesis.
