    Abstract: A microwave furnace has a furnace chamber formed between a chamber housing and a sintering platform for an object to be sintered. A microwave source is arranged for emitting microwaves into the furnace chamber. The microwave furnace further has a susceptor that comprises a material which over a temperature range of the material of at least 23 C to 700 C couples into microwaves. The susceptor and the furnace chamber are movable relative to each other between a first position, in which the susceptor is positioned relative to the furnace chamber, and a second position in which the susceptor is positioned further retracted from the furnace chamber relative to the first position. The invention helps providing a zirconia material with a relative homogeneous material structure.

    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.
