Abstract: A method and system for making a dental restoration are provided. The method comprises the step of providing a computer model of a three-dimensional reference surface that is based for example on a tooth structure of a tooth to be restored in a patient's dentition. The method further comprises the steps of visualizing the three-dimensional reference surface, providing a user operable virtual material deposition tool, and using the virtual material deposition tool to deposit a plurality of differently colored layers on the reference surface. The system provides functionality to perform the method of the invention. The invention preferably helps maximizing optical and geometrical quality in a dental restoration.
