Abstract: A dental prosthesis is made by externally machining successive layers of wax, each of which is formed on a previous prosthesis layer and/or on a coping. Each wax layer is used to form a mold in situ over the previous prosthesis layer/coping, and the appropriate prosthesis material is cast or otherwise molded to conform to the wax layer by the mold.

Abstract: A 3D virtual model of an intra oral cavity in which at least a part of a finish line of a preparation is obscured is manipulated in virtual space by means of a computer or the like to create, recreate or reconstruct finish line data and other geometrical corresponding to the obscured part. Trimmed virtual models, and trimmed physical models, can then be created utilizing data thus created. The virtual models and/or the physical models may be used in the design and manufacture of copings or of prostheses.

Abstract: According to the invention, a method and system are provided for scanning, and for facilitating scanning of, an intraoral cavity. The target parts of the intraoral cavity that it is desired to have scanned are identified, and the spatial s relationships between a scanning device and the target parts of the intraoral cavity suitable for enabling said target parts to be scanned by said scanning device, are also identified or otherwise determined. These relationships are then displayed, and the displayed relationships are used as a guide for scanning the intraoral cavity.

Abstract: A system for generating missing data for 3D models of intraoral structures of a patient. The system may include a hand-held intraoral scanner and a computer having instructions that the system to scan the intraoral structure of a patient to generate first 3D data of the surface of a prepared tooth, generate a 3D virtual model of the prepared tooth based on the first 3D data, determine the 3D virtual model is missing a surface associated with the prepared, generate second 3D data approximating the surface that is determined to be missing from the 3D virtual model intraoral structure that is missing, and combine the second 3D data with the 3D virtual model such that the 3D virtual model includes the approximated surface, wherein the approximated surface approximates the prepared tooth associated with the surface determined to be missing from the 3D virtual model.

Abstract: The invention provides a method for creating a physical teeth model. The method comprises the following steps: providing a virtual three dimensional (3D) representation of a patient's dentition that comprises at least a region of the teeth that includes a tooth stump on which a crown is to be fitted or a region on to which a bridge is to be fitted; and preparing a physical model of the jaws of a subject from a blank, based on information from said virtual 3D image.
