Abstract: A system for determining surface topography of a three-dimensional structure is provided. The system can include an illumination unit configured to output a two-dimensional array of light beams each comprising a plurality of wavelengths. An optical assembly can focus the plurality of wavelengths of each light beam to a plurality of focal lengths so as to simultaneously illuminate the structure over a two-dimensional field of view. A detector and a processor are used to generate data representative of the surface topography of the three-dimensional structure based on the measured characteristics of the light reflected from the structure.

Abstract: An apparatus is described for measuring surface topography of a three-dimensional structure. In many embodiments, the apparatus is configured to focus each of a plurality of light beams to a respective fixed focal position relative to the apparatus. The apparatus measures a characteristic of each of a plurality of returned light beams that are generated by illuminating the three-dimensional structure with the light beams. The characteristic is measured for a plurality of different positions and/or orientations between the apparatus and the three-dimensional structure. Surface topography of the three-dimensional structure is determined based at least in part on the measured characteristic of the returned light beams for the plurality of different positions and/or orientations between the apparatus and the three-dimensional structure.

Abstract: An apparatus adapted for confocal imaging of a non-flat specimen comprising a coherent 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 imaging optics comprise at least one optical component located so that the light reflected from the specimen surface passes therethrough on its way to the detector. The optical component is movable so as to move the at least one spot, within a range of movement, to a number of distinct locations in a plane perpendicular to the apparatus' optical axis, within the detector's integration time.

Abstract: A method and system for providing information for correct placement of one or more brackets on one or more corresponding teeth according to a predetermined treatment scheme. A virtual representation of a three-dimensional teeth arrangement of one or both jaws of the individual with brackets placed on said teeth is obtained wherein the position and orientation of the brackets on said teeth being designed so as to achieve a desired treatment outcome. The virtual representation is processed to generate an output data, the output data driving a display, such as a computer monitor or a printed nullhard-copynull, to display an image of at least one tooth with a bracket thereon, the displayed image having three-dimensional qualities indicative of said at least one tooth as viewed from a defined viewpoint. The invention can be applied to the placement of brackets onto the buccal side of the teeth as well as onto the lingual side of the teeth.

Abstract: A dental instrument and method for imaging the three-dimensional topography of one or more teeth in the oral cavity of an individual is provided. The instrument includes a probe insertable into the oral cavity to receive the image of these surfaces which can then be processed. Combined with the probe is an auxiliary which projects an air stream toward the surface to be imaged by the probe and acts to evaporate and remove from these surfaces a liquid film coating formed by saliva and other fluids present in the oral cavity, to render these surfaces dry and enhance their reflectivity and in doing so, provide clearer images.
