Abstract: Feedback data useful in prosthodontic procedures associated with the intra oral cavity is provided. First, a 3D numerical model of the target zone in the intra oral cavity is provided, and this is manipulated so as to extract particular data that may be useful in a particular procedure, for example data relating to the finish line or to the shape and size of a preparation. The relationship between this data and the procedure is then determined, for example the clearance between the preparation and the intended crown. Feedback data, indicative of this relationship, is then generated, for example whether the preparation geometry is adequate for the particular type of prosthesis.

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.

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.
