  • Patent number: 10390914
    Abstract: A method for processing prosthetic teeth for the production of a full denture or at least a partial denture with at least two prosthetic teeth, a device for holding prosthetic teeth for the implementation of the method, and a set for the implementation of the method with the device. The method includes the following steps: inserting at least two prefabricated prosthetic teeth with their coronal sides into recesses of an elastic mold, attaching a clamping device to the elastic mold, and applying mechanical pressure to exert force to affix the prosthetic teeth in the elastic mold, positioning and aligning the prosthetic teeth in a desired position and a desired alignment in relation to each other in the elastic mold, affixing the elastic mold with the clamping device and prosthetic teeth in a defined position in a holder of a CAM device for removing material of the prosthetic teeth with a CAM method, and basally ablating at least one of the prosthetic teeth affixed in the elastic mold with the CAM method.
