Abstract: Methods and apparatuses can include generating computer 3D models of an object, by registering two or more scans of physical models of an object. The scans may be 3D scans registered by a curve-based registration process. A method can include generating a 3D model of a portion of a patient's oral anatomy that can be used in dental restoration design. Scanning workflows can include scanning physical models of an object to obtain a 3D model. A scanner can scan physical models of a patient's dentition to obtain scans used to generate a 3D model of a patient's dentition.

Abstract: A computer-implemented method of designing a dental restoration at a display includes providing a virtual three dimensional representation of at least a portion of the patient's dental situation. The method includes displaying a library arch form in an alignment with the virtual three dimensional representation of the portion of the patient's dentition. The library arch form includes a pair of two virtual library teeth packing to each other. The method also includes in response to a parametric change of one of the two virtual library teeth, moving the other virtual library tooth to keep packing to the changed virtual library tooth.

Abstract: Computer-implemented methods of designing dental restorations and systems for performing the described methods are provided. In an embodiment, a method includes providing a virtual three dimensional representation of at least a portion of the patient's dentition that includes at least one preparation tooth, identifying a preparation margin on the virtual three dimensional representation, placing an arch form of a virtual tooth library in alignment with the virtual three dimensional representation, and proposing an initial restoration design based upon a tooth design obtained from the virtual tooth library.

Abstract: A computer-implemented method of routing a dental restoration design case to a user account includes receiving new dental restoration design cases associated with metadata describes design requirements. The method includes parsing the metadata to identify design factors indicating the requirements and storing the new cases in a main queue. The method also includes receiving login information, identifying the user account for the design user and retrieving attribute data associated with the account. The attribute data describes a design skill level of the design user. The method includes evaluating the design factors of the new dental restoration design cases in the main queue based on the attribute data of the account to determine a dental restoration design case in the main queue that satisfies the attribute data of the account and routing the determined dental restoration design case to a user queue associated with the user account.

Abstract: 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.
