摘要： An apparatus for determining surface topology of a portion of a three-dimensional structure is provided. An array of incident light beams passing through a focusing optics and a probing face is shone on said portion. The focusing optics define one or more focal planes forward of the probing face in a position which can be changed by the focusing optics. The beams generate illuminated spots on the structure and the intensity of returning light rays propagating in an optical path opposite to that of the incident light rays is measured at various positions of the focal plane(s). By determining spot-specific positions yielding a maximum intensity of the returned light beams, data is generated which is representative of said topology.

摘要： 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.

摘要： A system and device for positioning and fixing an orthodontic element on a surface of a tooth are provided. The positioning of the element on a tooth is accomplished by: bringing the element into proximity of the tooth while continuously capturing an image of at least the tooth or of the element, and an image of both, once the tooth and the element are proximal to one another; transmitting the image or its representation to a display for displaying a real-life image of the captured image or representation together with indicators providing guidance information on intended position of the orthodontic element on the tooth's surface; positioning the element on a tooth's surface; positioning the element on a tooth's surface according to said indicators such that the element's position coincides with the intended position; and fixing the element onto the tooth. A device for marking a position on a surface of a tooth for later placement of an orthodontic element is also provided.
