    摘要: 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.

    摘要: A system and method for making a layered dental appliance. The system can include a first mold comprising a negative of a first layer of a layered dental appliance, a second mold comprising a negative of a second layer, and a dental core dimensioned to be at least partially received in the first mold and the second mold. The method can include positioning a first slurry in the first mold, and pressing the dental core into the first slurry to form a first article comprising the dental core and a first layer formed from the first slurry. The method can further include removing the first article from the first mold, positioning a second slurry in the second mold, and pressing the first article into the second slurry to form a second article comprising the dental core, the first layer, and a second layer formed from the second slurry.
