The invention relates to the processing of data regarding the three dimensional shape of a dental prosthesis, which has two prosthesis sections and a connector section, said connector section being connected to the two prosthesis sections and less stable than the two prosthesis sections, comprising the steps that:-a stability parameter and a stability criterion are determined for the connector section；-for the stability parameter, the actual value is calculated from the data；-it is checked for the connector section as to whether the actual value fulfills the stability criterion, and if not, that a warning signal is generated, wherein the determination of the stability criterion is dependent on at least one of the following prosthesis attributes:-the configuration of the prosthesis；-the position of the prosthesis inside the mouth；-the material and/or the cross-sectional profile of the connector section；-the type of the prosthesis sections adjoining the connector section.
