摘要： Templates are disclosed that permit an orthodontist to accurately place appliances such as bracket shims or brackets on a tooth or teeth at a desired position. The templates can be used for accurately locating the position of other dental or orthodontic procedures, such as varnishing, tooth etching and root canals. The templates are made from a flexible sheet of material adapted to be adhered directly to the surface of the tooth or teeth. The sheet of material is formed with the outline of the tooth or teeth or in the shape of the tooth to allow the template to be posited in a proper, reference position. The sheet of material is also formed with one or more marks indicating the location of the bracket on the tooth, for example one mark indicting the bracket base location and other marks indicating the orientation of the base and bracket slot. The mark indicating the bracket base is punched out or otherwise removed from the sheet to provide a void in the template, enabling the user to directly bond the bracket to the tooth at the location of the void.

摘要： An interactive, unified workstation is described that unifies in a single system multitude of functions pertaining to a practitioners practice that would otherwise require disjointed, more expensive, and less efficient individual workstations dedicated to a specific, limited task or a sub-set of tasks. The invention is directed towards benchmarking for a practitioner's business practice, and for clinical aspects of treatment planning; and integrating overall patient care planning functions. The unified workstation further facilitates access to archived database resources and facilitates both knowledge base services to practitioners and also hybrid treatment planning, wherein different types of appliance systems (fixed, such as brackets and wires, or removable, such as aligning shells) may be used during the course of treatment.

摘要： A single surface representation is created from a cloud of points. Each point in the cloud of points is assigned three-dimensional spatial coordinates. The cloud of points is stored in a memory of a computer. Machine-executable instructions are provided for the computer that operate on the cloud of points. The instructions construct an initial triangle from the cloud of points. The instructions construct a multitude of adjacent triangles forming a single continuous surface representing the object. The triangles comprise planar surfaces having three vertices. The vertices of the adjacent triangles comprise the three points forming the initial triangle and a multitude of other points. Except for the initial two points, the points forming the triangles are each computed as a weighted average of a set of nearby points in the cloud of points that satisfy selection criteria. The resulting vertex also has to satisfy one or more selection criteria. The final weighted average surface representation requires much less data to represent the object surface than the initial point cloud.

摘要： A method is described for taking a three-dimensional virtual model of the dentition and associated anatomical structures of a patient and isolating individual teeth from the rest of the anatomical structure, e.g. gums, to thereby produce individual, virtual three-dimensional tooth objects. The individual tooth objects can be displayed on the display of an orthodontic workstation and moved independently from each other, and thereby form the basis of planning treatment for the patient. The individual, virtual three-dimensional tooth objects are created by comparing the virtual model of the dentition to virtual, three-dimensional template teeth that are stored in memory in a process described in detail herein. The template teeth can include roots as well as crowns. The template teeth can be stored objects acquired from some external source or alternatively developed from a database of patient scans. Virtual three-dimensional brackets are also stored in the memory of the workstation. The virtual brackets can be placed on the virtual teeth and moved relative to the teeth as needed in a preliminary step in treatment planning.

摘要： A method and system are provided for constructing a virtual three-dimensional model of an object using a data processing system, and at least one machine-readable memory accessible to said data processing system. A set of at least two digital three-dimensional frames of portions of the object are obtained from a source, such as a computing system coupled to an optical or laser scanner, CT scanner, Magnetic Resonance Tomography scanner or other source. The at least two frames comprise a set of point coordinates in a three dimensional coordinate system providing differing information of the surface of the object. The frames provide a substantial overlap of the represented portions of the surface of the object, but do not coincide exactly for example due to movement of the scanning device relative to the object between the generation of the frame. Data representing the set of frames are stored in the memory. The data processing system processes the data representing the set of frames with said data processing system so as to register the frames relative to each other to thereby produce a three-dimensional virtual representation of the portion of the surface of the object covered by said set of frames. The registration is performed without using pre-knowledge about the spatial relationship between the frames. The three-dimensional virtual model or representation is substantially consistent with all of the frames.

摘要： A scanning system includes a hand-held scanning device that generates two-dimensional images of a pattern reflected off an object. The system also includes a memory and processing unit. The memory stores a calibration table for the scanner and received scanned bitmap images. The processing unit generates three-dimensional information as to a scanned object. The scanning can be performed without knowledge or even precise control of the position of the object relative to the scanner. Random movement of the object during scanning is also possible. For example, the scanner is simply swept over the surface of the object by hand. Three-dimensional information of the object is obtained from the captured images using a calibration table for the scanner. A method of calibration of the scanner in X, Y and Z directions is also described. The scanner can be used for a variety of purposes, including medical and industrial purposes. The illustrated embodiment is in-vivo scanning of human teeth for purposes of orthodontic treatment planning and diagnosis.

摘要： The present invention discloses orthodontic treatment planning which enables designing the desired smile line with the help of a computer workstation.A new lip trace feature enables cutting out the portion of a photograph corresponding to the area inside the lips. The 3D model of the teeth is then completely visible when overlaid with the facial photograph.One can use this feature to superimpose the patient photo over the 3-D model of the teeth to see how much intrusion or extrusion is needed to design the smile line.Three dimensional model of dentition obtained by scanning of teeth along with the patient's two dimensional facial photograph is used to design the desired smile line for the patient by means of software instructions in the workstation.
