Publication number: 20060107720Abstract: An apparatus for bending orthodontic wires has means for guiding and holding a wire. In order to prevent forces resulting from compressive or stretching strain during the bending process, one of these means does not apply any longitudinal forces onto the wire by design. In another implementation, the apparatus for bending orthodontic wires has a gimbal-mounted gripper for bending the wire. Furthermore, a method is disclosed for applying two bends at the same longitudinal wire location in two different directions.Type: ApplicationFiled: November 22, 2004Publication date: May 25, 2006Inventors: Ruedger Rubbert, Thomas Weise

Patent number: 7027642Abstract: 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 the data processing system. A set of at least two digital three-dimensional frames of portions of the object are obtained from a scanner or other source comprising 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. Data representing the set of frames are stored in the memory and processed by the 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 the set of frames.Type: GrantFiled: April 13, 2001Date of Patent: April 11, 2006Assignee: OraMetrix, Inc.Inventors: Rüdger Rubbert, Thomas Weise, Peer Sporbert, Hans Imgrund, Dimitrij Kouzian

Patent number: 6971873Abstract: 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: GrantFiled: May 1, 2002Date of Patent: December 6, 2005Assignee: OraMetrix, Inc.Inventors: Rohit Sachdeva, Rüdger Rubbert, Thomas Weise

Patent number: 6851949Abstract: A method and apparatus for generating a three-dimensional digital model of a desired orthodontic structure include processing that begins by obtaining a three-dimensional model of an actual orthodontic structure, wherein the three-dimensional digital model is defined in x, y, z space. The processing then continues by generating an interim three-dimensional model of the desired orthodontic structure less teeth. The interim three-dimensional model is designed in x, y, z space and includes the desired placement of an occlusal plane, an upper-arch form, a lower-arch form, an upper-arch midline, and a lower-arch midline. The processing then continues by positioning the upper and lower teeth with respect to the interim digital model and the defined x, y, z space to obtain a first pass three-dimensional digital model of the desired orthodontic structure. The processing continues by determining whether achieving the first pass three-dimensional model is feasible.Type: GrantFiled: April 28, 2000Date of Patent: February 8, 2005Assignee: OraMetrix, Inc.Inventors: Rohit Sachdeva, Rüdger Rubbert

Publication number: 20040243938Abstract: An interface 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 identifiers of other nodes. 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: ApplicationFiled: June 10, 2004Publication date: December 2, 2004Inventors: Thomas Weise, Ruedger Rubbert

Patent number: 6632089Abstract: An interactive, software-based treatment planning method to correct a malocclusion is described. The method can be performed on an orthodontic workstation in a clinic or at a remote location such as a lab or precision appliance manufacturing center. The workstation stores a virtual three-dimensional model of the dentition of a patient and patient records. The virtual model is manipulated by the user to define a target situation for the patient, including a target archform and individual tooth positions in the archform. Parameters for an orthodontic appliance, such as the location of orthodontic brackets and resulting shape of an orthodontic archwire, are obtained from the simulation of tooth movement to the target situation and the placement position of virtual brackets. The treatment planning can also be executed remotely by a precision appliance service center having access to the virtual model of the dentition.Type: GrantFiled: April 13, 2001Date of Patent: October 14, 2003Assignee: OraMetrix, Inc.Inventors: Rüdger Rubbert, Thomas Weise, Rohit Sachdeva, Hans Imgrund, Peer Sporbert, Mario Leichner, Jens Troeger, Dimitrij Kouzian, Stephan Maetzel
