Abstract: A method for for comparing between an orthodontic element's actual position on the surface of a tooth and a proper position comprise monitoring the element, the tooth or both once the element and the tooth are proximal to one another by an image acquisition unit which transmits an image to a screen that displays the image and displaying information on the screen regarding proper position of the element in a manner allowing to compare between the actual and the proper position is disclosed. Further disclosed is a system and device for positioning of an orthodontic element or a marking device having a marking member for marking a position for subsequent placement of an orthodontic element on a surface of a tooth.

Abstract: The invention provides a method and system for obtaining a three-dimensional representation of a patient's teeth arrangement. A three-dimensional physical teeth model is provided, having a surface relief corresponding to the patient's teeth arrangement. Computerized tomography (CT) is applied to the three-dimensional physical teeth model, to thereby acquire data of multiple slices of at least a portion of the teeth model. The data is analyzed to produce a virtual three-dimensional representation of the teeth model or a portion thereof.

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.
