Abstract

See full text

The invention relates to the processing of data regarding the three dimensional shape of a dental prosthesis, having two prosthesis sections and a connector section, wherein the connector section is connected to the two prosthesis sections and is less stable than the two prosthesis sections. The method includes the steps of (a) determining a stability parameter and a stability criterion for the connector section, (b) calculating the actual value for the stability parameter from the data, (c) checking the connector section to determine whether the actual value fulfills the stability criterion, and if not, generating a warning signal is to the user.
