Publication number: 20050069188Abstract: 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: ApplicationFiled: September 29, 2004Publication date: March 31, 2005Inventors: Rudger Rubbert, Thomas Weise, Peer Sporbert, Hans Imgrund, Dimitrij Kouzian

Publication number: 20040214128Abstract: A method and apparatus for facilitating placement and evaluation of virtual appliances on virtual teeth of an orthodontic patient are described. Positioning references comprising bracket height, occlusal plane, or any arbitrary plane are provided to facilitate desired placement of virtual appliances on virtual teeth model. The process can be applied with any dentition state of a patient such as malocclusion, target state from treatment, or intermediate monitored state during the course of a treatment. An unified workstation for treatment planning provides the computer software tools for verification, simulation and evaluation of the virtual appliance placement. The process enables proper planning of treatment for an orthodontic patient suffering from malocclusion involving bonding of virtual brackets to the surface of the patient's virtual teeth with archwires placed in the slots of the brackets, so as to realize the desired results from the treatment in the most desired manner.Type: ApplicationFiled: March 2, 2004Publication date: October 28, 2004Inventors: Rohit Sachdeva, Peer Sporbert, Stephan Maetzel, Hans Imgrund, Claudia Strauss, Phillip Getto

Publication number: 20040073417Abstract: 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: ApplicationFiled: October 9, 2003Publication date: April 15, 2004Applicant: OraMetrix, Inc.Inventors: Rudger Rubbert, Thomas Weise, Rohit Sachdeva, Hans Imgrund, Peer Sporbert, Mario Leichner, Jens Troeger, Dimitrij Kouzian, Stephan Maetzel

Publication number: 20040015327Abstract: An integrated system is described in which digital image data of a patient, obtained from a variety of image sources, including CT scanner, X-Ray, 2D or 3D scanners and color photographs, are combined into a common coordinate system to create a virtual three-dimensional patient model. Software tools are provided for manipulating the virtual patient model to simulation changes in position or orientation of craniofacial structures (e.g., jaw or teeth) and simulate their affect on the appearance of the patient. The simulation (which may be pure simulations or may be so-called “morphing” type simulations) enables a comprehensive approach to planning treatment for the patient. In one embodiment, the treatment may encompass orthodontic treatment. Similarly, surgical treatment plans can be created. Data is extracted from the virtual patient model or simulations thereof for purposes of manufacture of customized therapeutic devices for any component of the craniofacial structures, e.g.Type: ApplicationFiled: May 2, 2003Publication date: January 22, 2004Applicant: OraMetrix, Inc.Inventors: Rohit Sachdeva, Sanjeev Taneja, Peer Sporbert, Phillip Getto, Stephan Maetzel, Hans Imgrund, Charles L.

Publication number: 20030021453Abstract: Method and apparatus for registering an object of known predetermined geometry to scanned three dimensional data such that the object's location may be verified. Such a known object may comprise a less than ideal three-dimensional (3-D) digital object such as a tooth, a dental appliance (e.g., as a tooth bracket model) or other like object, including portions thereof. Knowledge of such an object's location is generally helpful in planning orthodontic treatment, particularly where the location of the object needs to be determined or confirmed or where incomplete or poor scan data is obtained. Aspects of the present invention provide methods of effectively verifying dental appliance location and displaying appliance locations using a computer and three-dimensional models of teeth.Type: ApplicationFiled: May 1, 2002Publication date: January 30, 2003Inventors: Thomas Weise, Rudger Rubbert, Hans Imgrund, Peer Sporbert, Stephan Maetzel

Publication number: 20020180760Abstract: 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: April 13, 2001Publication date: December 5, 2002Applicant: OraMetrix, Inc.Inventors: Rudger Rubbert, Thomas Weise, Peer Sporbert, Hans Imgrund, Mario Leichner, Rohit Sachdeva

Publication number: 20020150859Abstract: Occlusal contact between upper and lower virtual three-dimensional teeth of a patient when the upper and lower arches are in an occlused condition are determined and displayed to the user on a user interface of a general purpose computing device. Various techniques for determining occlusal contacts are described. The areas where occlusal contact occurs is displayed on the user interface in a readily perceptible manner, such as by showing the occlusal contacts in green. If the proposed set-up would result in a interpenetration of teeth in opposing arches, such locations of interpenetration are illustrated in a contrasting color or shading (e.g., red). The ability to calculate distances and display occlusal contacts in a proposed set-up assists the user in planning treatment for the patient. The process can be extended to interproximal contact detection as well. The concepts also apply to dental prosthetics, such as crowns, fillings and dentures.Type: ApplicationFiled: May 1, 2002Publication date: October 17, 2002Applicant: OraMetrix, Inc.Inventors: Hans Imgrund, Rudger Rubbert, Dimitij Kouzian, Peer Sporbert, Stephan Maetzel, Rohit Sachdeva
