  • Patent number: 12285304
    Abstract: The invention relates to a method for providing a physical testing model for testing a fitting of a dental restoration to be hardened before the dental restoration being hardened. The dental restoration is required to fit onto a dental element after being hardened. The method comprises providing a 3D digital model of the dental element. Size of the 3D digital model of the dental element is scaled using a first scaling factor. The first scaling factor depends on an inverse of a second scaling factor quantifying a predicted scaling of the size of the dental restoration to be hardened due to the hardening. The scaling of the 3D digital model of the dental element results in a 3D digital testing model for the testing of the fitting of the dental restoration to be hardened. The 3D digital testing model is provided as a template for manufacturing the physical testing model.

  • Patent number: 12193894
    Abstract: The invention relates to a computer-implemented method for providing a set of layer-specific molding matrices for reconstructing layer-by-layer one or more teeth of a set of teeth in a patient's oral cavity. The set of layer-specific molding matrices comprises two or more layer-specific molding matrices. Each of the layer-specific molding matrices is configured for being arranged on the set of teeth and for casting a different layer of the one or more teeth to be reconstructed with a layer-specific reconstruction material inserted into the respective layer-specific molding matrix. The respective layer-specific molding matrix defines a 3D geometric form of the respective layer being casted.

  • Patent number: 11980511
    Abstract: The invention relates to a computer-implemented method for assessing a clearance between a tooth element to be provided with a dental restoration element and an antagonist of the tooth element. A 3D digital teeth model with 3D digital representations of the tooth element and of a surface area of the antagonist is received. The surface area is offset from the antagonist by adding an offset. The resulting offset surface area defines a limit for the tooth element. For the clearance it is checked, whether the tooth element violates one or more penetration criteria regarding the offset surface area. If the tooth element violates the one or more penetration criteria, the clearance is assessed to be insufficient for the tooth element to be provided with the dental restoration element. Else the clearance is assessed to be sufficient. The result of the assessment is output.

  • Patent number: 11514200
    Abstract: The invention relates to a method for modelling a patient-individualised denture part (140). The method comprises providing a digital three-dimensional patient situation model (118), a digital three-dimensional denture part model (114), and one or more geometric adaptation criteria defined using patient-specific delimiting surfaces. A denture part geometry of the denture part model is adapted in a patient-individualised manner to a patient situation geometry of the patient situation model. The patient-individualised adaptation process also comprises repeatedly interactively making user-defined changes to the denture part model, wherein the denture part model dynamically passes through a sequence of intermediate states during the course of each of the user-defined changes until a change state resulting from each user-defined change is reached.
