摘要： The invention relates to a computer-implemented method for providing a template for a casting matrix configured for casting one or more artificial gingiva parts of a removable denture. The casting matrix comprises one or more recesses. Each of the recesses has a 3D geometric form, which is a negative of a 3D geometric form of a section of the removable denture with one of the artificial gingiva parts to be casted.

摘要： The invention relates to an assembly set for a removable partial denture comprising one or more replacement teeth as well as a framework with one or more retention sections. Each of the retention sections is configured to receive and retain one or more of the replacement teeth. Each of the replacement teeth comprises a bottom face with a surface structure configured to engage an assigned complementary retention structure provided by one of the retention sections of the framework configured to receive the respective replacement tooth. Each surface structure provides in combination with the assigned complementary retention structure a non-destructive detachable direct connection between the replacement tooth comprising the respective surface structure and the retention section comprising the respective assigned complementary retention structure.

摘要： The invention relates to a method for determining a preparation surface of a tooth for preparing the tooth for receiving a dental restoration element. The method comprises receiving a three-dimensional digital tooth model, a three-dimensional digital restorative tooth model, a definition of a restoration area, a first value selected for a basic preparation depth of the preparation, and a second value selected for a restoration thickness of the dental restoration element. The method further comprises determining a first reference surface using the selected first value, determining a second reference surface using the selected second value, determining one or more preparation reference surface sections using the first and second reference surface, and determining the preparation surface of the tooth using the determined one or more preparation reference surface sections.

摘要： Disclosed herein is a dental method that comprises receiving a selection of a replacement tooth for a subject. The method further comprises receiving one or more three-dimensional digital tooth models descriptive of one or more teeth of the subject. The method further comprises receiving a generated three-dimensional digital model of the replacement tooth in response to inputting the one or more three-dimensional digital tooth models descriptive of one or more teeth of the subject into a tooth model generating neural network. The tooth model generating neural network comprises an encoder portion and a decoder portion. The encoder portion is configured for outputting a collective feature vector descriptive of the one or more digital tooth models. The tooth model generating neural network further comprises at least one fully connected layer configured to output a latent space vector into the decoder portion in response to receiving the collective feature vector.

摘要： The invention relates to a method for configurating a patient individual physical transfer key for transferring a virtually defined first position of a three-dimensional virtual representation of a physical model of a patients dentition within a 3D virtual representation of a physical articulator to the physical model of the patients dentition and the physical articulator. A 3D virtual representation of the physical transfer key is generated and provided for generating the physical transfer key. The transfer key is configured to be connected to a first support section of the articulator and to support a first one of the 3D virtual representations of the model components of the dentition model at the first position.

摘要： Disclosed herein is a method of applying dental cement to a concave surface of a dental restoration element. The concave surface of the dental restoration element is configured to mate with a first convex surface of a dental mounting structure such that there is a dental cement gap between the concave surface and the first convex surface. The method comprises: receiving the dental restoration element; receiving a cement applicator, wherein the cement applicator comprises a second convex surface, wherein the second convex surface is a transformation of the first convex surface such that it is shrunk by a reduction factor; applying the dental cement to the concave surface; inserting the second convex surface of the cement applicator into the concave surface of the dental restoration element; and removing the cement applicator from the dental restoration element to provide the dental restoration element with the applied dental cement.
