Patent number: 7197179Abstract: 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.Type: GrantFiled: September 29, 2004Date of Patent: March 27, 2007Assignee: OraMetrix, Inc.Inventors: Rüdger Rubbert, Thomas Weise, Peer Sporbert, Hans Imgrund, Dimitrij Kouzian

Patent number: 7188308Abstract: An interface and a method is provided for permitting a user to explore a collection of data. The data collection provides nodes as structural elements, and references which are assigned to nodes and hold the address of another node. Multiple references can be assigned to each node, thus guiding a user of the system to multiple other nodes, and multiple references can hold the same address, so that multiple nodes can have references pointing to the same node. The interface allows visualizing the network created by the interconnection of the nodes on a display region. The interface also allows the user to intuitively navigate along the references in both directions of the references, so that the user can explore which nodes are referenced by a certain node, and also by which nodes a certain node is referenced.Type: GrantFiled: April 8, 2003Date of Patent: March 6, 2007Inventors: Thomas Weise, Ruedger Rubbert

Publication number: 20070015104Abstract: A customized orthodontic bracket system is provided. The system can include a bracket having a customized bracket bonding pad for bonding the bracket to a tooth of a patient and a bracket slot adapted to receive a customized archwire. The customized archwire is adapted to be positioned in the bracket slot to form a precise bracket slot-archwire interface. The bracket slot and the archwire when positioned in the bracket slot can be positioned substantially adjacent the tooth surface to reduce induced vertical error in tooth positioning. The bracket slot can be configured to have a bracket slot width substantially matching a cross-section of the archwire to reduce torque rotation around an axis of the archwire when positioned therein to further enhance end-of-treatment tooth positioning and reduce overall treatment time.Type: ApplicationFiled: September 18, 2006Publication date: January 18, 2007Inventors: Dirk Wiechmann, Ralf Paehl, Rudger Rubbert, Thomas Weise

Publication number: 20060281041Abstract: 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.Type: ApplicationFiled: May 19, 2006Publication date: December 14, 2006Inventors: Rudger Rubbert, Thomas Weise, Peer Sporbert, Hans Imgrund, Mario Leichner, Rohit Sachdeva

Publication number: 20060228010Abstract: 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.Type: ApplicationFiled: March 23, 2006Publication date: October 12, 2006Inventors: Rudger Rubbert, Thomas Weise, Peer Sporbert, Hans Imgrund, Hans-Florian Geerdes, Lutz Pfeil, Peter See

Publication number: 20060078842Abstract: An orthodontic workstation stores a library of virtual three-dimensional brackets in a memory. Each of the virtual brackets has a unique three-dimensional configuration and prescription. Typically, the library of bracket comprises a library of commercially available, off-the-shelf brackets. The workstation further includes an interactive treatment planning program that permits a user to move teeth from a virtual model of the dentition to a proposed set-up. In one possible embodiment, the treatment planning program provides the ability to display a virtual bracket placed on a virtual tooth and change the prescription or configuration of the virtual bracket. The treatment program automatically compares the modified prescription with the prescription information of the virtual brackets in the library and selects a bracket from the library that most closely matches the virtual bracket displayed on the tooth. Thus, the user does not have to use customized brackets.Type: ApplicationFiled: October 7, 2005Publication date: April 13, 2006Inventors: Rohit Sachdeva, Rudger Rubbert, Thomas Weise
