  • Patent number: 7104792
    Abstract: A positioning appliance adapted to facilitate an orthodontics procedure in which a bracket or other orthodontic component is placed at a desired site on the surface of a tooth and affixed thereto. The appliance comprises a hand-held tubular wand that has a protective sleeve section and a camera section telescoped in the sleeve section. A window is mounted at the front end of the sleeve section and a finger projecting therefrom is adapted to hold the bracket at a position abutting the tooth surface. A camera is housed in the camera section to capture through the window an image of the bracket on the surface of the tooth. One or more light sources are housed in the camera section, for irradiating the bracket and the tooth surface with light detectable by the camera. Additional one or more light sources are housed in the camera section and are capable of irradiates light at a wavelength that can cure an adhesive used for affixing the bracket or other orthodontic component to the surface of a tooth.

  • Patent number: 7092107
    Abstract: 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.

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 (t2) 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.

  • Patent number: 7074039
    Abstract: A virtual orthodontic treatment method and a system thereof, the method comprising the following: providing a virtual diagnostic setup model of teeth of at least one jaw of an individual, associating each teeth in said model with its corresponding virtual orthodontic appliance to obtain a first composite model and repositioning teeth into an initial treatment state according to pre-defined appliances-dependent rules. In the initial treatment state, selecting one or more teeth and reassociating the teeth with their corresponding virtual orthodontic appliance by changing the position of the appliance corresponding to the selected tooth thereby causing repositioning of the teeth according to the appliance-dependence rules. An altered treatment state is obtained, yielding a better grade, according to one or more systems for grading an orthodontic model, as compared to the grade of the initial treatment state.

  • Patent number: 7030383
    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.

  • Publication number: 20040175670
    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 “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.
