    摘要： Systems and methods are provided for machining dental prostheses including, over a network, receiving data concerning a dental prosthesis, selecting a material from which to machine the dental prosthesis, and determining machining instructions for machining the dental prosthesis based on a nominal enlargement factor corresponding to the selected material. The method can also include storing the machining instructions, receiving a request from a milling machine for a dental prosthesis to be milled by the milling machine, and associating the dental prosthesis with the milling machine. The method can also include selecting a material blank comprised of the selected material, determining a material blank enlargement factor of the selected material blank, modifying the machining instructions according to a difference between the nominal enlargement factor and the material blank enlargement factor, and machining the dental prosthesis according to the modified machining instructions.

    摘要： A machinable preform for shaping into dental restorations is described that comprises material having suitable strength for use in dental applications without requiring further processing after shaping to strengthen the material (such as sintering). In one embodiment, a preform is comprised of a machinable dental material having a Vickers hardness value in the range of 4HV GPa to 20HV GPa, and comprises a body and a stem that extends from the outer surface of the body that supports the body during shaping. A method for making the machinable preform, and a kit comprising a machinable preform and a grinding tool, are also described.

    摘要： A method for compact and descriptive representation of teeth shape (or other anatomic shapes) in terms of characteristic curves and its application to generation of automatic designs within dental CAD software or other software is provided. In an embodiment, a method includes capturing tooth shape by a network of characteristic curves (i.e. margin lines). In an embodiment, a method includes compactly encoding curves as strings, which then can be indexed and searched efficiently by similarity. In an embodiment, a method includes retrieving high quality crown design proposals from a case repository based on similarity of margin lines.
