Abstract: Provided is a device for determining the surface topology and associated color of a structure, such as a teeth segment, including a scanner for providing depth data for points along a two-dimensional array substantially orthogonal to the depth direction, and an image acquisition means for providing color data for each of the points of the array, while the spatial disposition of the device with respect to the structure is maintained substantially unchanged. A processor combines the color data and depth data for each point in the array, thereby providing a three-dimensional color virtual model of the surface of the structure. A corresponding method for determining the surface topology and associated color of a structure is also provided.
Abstract: A method and system are provided for providing patient data useful for dental procedures, including scanning a dental structure of a patient when coupled to a geometric structure to provide a virtual model representative of the coupling and the dental structure, and relating the virtual model to a body reference of the patient.
Abstract: A dental articulator is provided in which at least one of the two arms thereof has a base member that is articulated with respect to a bracket element onto which a dental model may be mounted, allowing independent movement of the dental model with respect to the pivot axis hingedly linking the arms.

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: An apparatus for determining surface topology of a portion of a three-dimensional structure is provided, that includes a probing member, an illumination unit, a light focusing optics, a translation mechanism, a detector and a processor.

Abstract: A virtual model of an intraoral cavity is provided, wherein this process is initialized by a dental clinic, and the design and manufacture of a suitable dental prosthesis for the intraoral cavity is shared between a dental lab and a service center.
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: A method and system are provided for manufacturing a physical dental model. A virtual model is provided representative of at least a portion of the intra-oral cavity including at least one dental implant implanted therein, and the virtual model includes a virtual portion representative of each dental implant. The virtual spatial disposition of each such virtual portion is determined with respect to the virtual model, corresponding to a real spatial disposition of the respective implant with respect to the intra oral cavity. A physical model is then manufactured based on the virtual model, the physical model including a physical analog corresponding to each implant at a respective physical spatial disposition with respect to the physical model corresponding to the respective virtual spatial disposition of the respective virtual portion with respect to the first virtual model as already determined.
Abstract: An apparatus for determining surface topology of a portion (26) of a three-dimensional structure is provided, that includes a probing member, an illumination unit, a light focusing optics, a translation mechanism, a detector and a processor.

Abstract: An apparatus is adapted for confocal imaging of a non-flat specimen, and includes a light source for producing a light beam, imaging optics adapted to focus the light beam into at least one spot on a surface of a specimen, and a detector adapted to receive and detect light reflected from the specimen surface. The light source includes an optical system for converting a coherent beam into a plurality of beams, each of which is modified by a moving diffuser within a range of movement that is correlated to the detector's integration time.
