摘要： 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 'hard-copy', 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.

摘要： Determining surface topology of a portion (26) of a three-dimensional structure is provided. An array of incident light beams (36) passing through a focusing optics (42) and a probing face is shone on said portion. The focusing optics defines one or more focal planes forward the probing face in a position which can be changed (72) by the focusing optics. The beams generate illuminated spots (52) 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 (60) 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. Measurement of teeth. Light beams by grating of matrix of pinholes, micro lens array. Simultaneous imaging from three angles. Quicker with three different light components.

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.

摘要： A method for obtaining a dental occlusion map of a three-dimensional virtual computer model of teeth of upper and lower jaws of a mouth. The occlusion map indicates the distances between opposite regions on facing surfaces of opposite teeth of the upper and lower jaws of the mouth. The method includes the steps of determining the distances between opposite regions on opposite teeth of the upper and lower jaws of the mouth, and setting up a correspondence between the determined distances and regions on a mapping surface.

摘要： 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.
