摘要： Methods for digitizing complex surfaces of dental objects such as impressions of dental surfaces and shapes. While an impression mold is being scanned by translation along a known trajectory, typically in a plane, the line of sight of a distance probe is directed toward successive positions on the surface of the impression mold, such as by a periodic series of reflecting surfaces characterized by normal vectors at distinct non-orthogonal angles with respect to their axis of symmetry. One or more reference objects are scanned using the same translation and mirror positioning systems. Gathered coordinate data are processed to apply angular corrections and combined to form a single distortion-corrected image of the impression mold. An apparatus and methods are provided for measuring both sides of a dental object separately, and then registering the two sides relative to each other in a digital representation of the object.

摘要： Methods and apparatus for registration of digital images of a plurality of dental surfaces of a patient. Multiple dental surfaces are separately scanned and digitized, where each of the surfaces has at least one marked area. All marked areas are optically acquired, creating digitized images of the plurality of dental surfaces, which are then registered in a common reference frame on the basis of a specified marked areas. In some cases, a first dental surface is disposed on an upper dental arch and a second dental surface is disposed on a lower dental arch. Marked contact areas may be indicative of local occlusion pressure.

摘要： Methods and apparatus for projecting a tangible image of data characterizing an object onto a surface of the object itself. Three-dimensional measurements of the object are obtained, the measurements are processed for projection, and a tangible image is projected onto the object, the image conveying information based on the three-dimensional measurements. The image may be projected concurrently with performance of measurements. In an exemplary dental context, information derived in part from three-dimensional measurements of a tooth or replica may be projected onto the actual tooth or replica. In interactive application, a work piece is be measured during the course of fabrication, and three-dimensional information, derived from contemporaneous non-contact measurement, is projected onto the work piece in order to direct the user with the formation of the work piece.
