摘要： A method of making a monolithic dental restoration. The method includes the steps of providing a monolithic precursor of a dental restoration and firing the monolithic dental restoration precursor to provide the monolithic dental restoration. The zirconia material of both the dental restoration precursor as well as the dental restoration has a relative density of greater than 98% of the theoretic density of the zirconia material. The invention helps providing a color of a non-glazed dental restoration which resembles the color of a glazed dental restoration.

摘要： A method of making a physical object by additive manufacturing. In the method a hardenable primary material is provided, the object is built up by successively hardening layers of the hardenable primary material, and the object is cleaned from excess material by moving the object and thereby generating a mass inertial force in the excess material. The invention facilitates the making of objects by additive manufacturing.
