1. A method of using a physical testing model for testing a fitting of a manufactured dental restoration to be hardened before the manufactured dental restoration being hardened, the manufactured dental restoration being required to fit onto a dental element after being hardened, the method comprising:
providing a 3D digital model of the dental element;
scaling a size of the 3D digital model of the dental element using a first scaling factor, the first scaling factor depending 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 resulting in a 3D digital testing model for the testing of the fitting of the dental restoration to be hardened;
providing the 3D digital testing model as a template for manufacturing the physical testing model;
manufacturing the physical testing model using the 3D digital testing model as the template, the manufactured physical testing model being a physical copy of the template;
manufacturing the dental restoration to be hardened without using the physical testing model;
providing the manufactured dental restoration to be hardened;
testing the fitting of the manufactured dental restoration to be hardened onto the physical testing model;
when the fitting violates one or more fitting criteria, adjusting the manufactured dental restoration to be hardened in order to adjust the fitting onto the physical testing model and satisfy the one or more fitting criteria that is violated; and
hardening the manufactured dental restoration to be hardened.
