Patent number: 7296996Abstract: 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: GrantFiled: March 2, 2004Date of Patent: November 20, 2007Assignee: OraMetrix, Inc.Inventors: Rohit Sachdeva, Peer Sporbert, Stephan Maetzel, Hans Imgrund, Claudia Strauss, Phillip Getto

Publication number: 20070207437Abstract: 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., orthodontic appliances.Type: ApplicationFiled: May 1, 2007Publication date: September 6, 2007Inventors: Rohit Sachdeva, Sanjeev Taneja, Peer Sporbert, Phillip Getto, Stephan Maetzel, Hans Imgrund, Charles Abraham

Patent number: 7172417Abstract: 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: GrantFiled: December 13, 2004Date of Patent: February 6, 2007Assignee: OraMetrix, Inc.Inventors: Peer Sporbert, Hans Imgrund, Dimitij Kouzian, Stephan Maetzel, Rohit Sachdeva, Rüdger Rubbert

Publication number: 20060263740Abstract: A method and apparatus is provided for digitally checking the insertion quality of a target customized virtual arch wire designed during treatment planning prior to actually manufacturing the target arch wire. The method includes the steps of digitally simulating the insertion of the customized target virtual arch wire into the virtual brackets placed up on virtual teeth of a patient in an initial state of interest for checking if the arch wire could be inserted into the virtual brackets without conflicts or collisions. The initial state may be a malocclusion state or any intermediate treatment state of the patient. In the event the target virtual arch wire would cause conflicts, then the simulation optimizes the arch wire design in an attempt to eliminate the conflicts. In another aspect, a method is provided for selecting the recommended starting point for inserting the customized arch wire in the brackets placed on the dentition of the patient in the initial state.Type: ApplicationFiled: September 23, 2005Publication date: November 23, 2006Inventors: Peer Sporbert, Dimitij Kouzian, Hans Imgrund, Stephan Maetzel

Patent number: 7029275Abstract: Interactive, computer based orthodontist treatment planning, appliance design and appliance manufacturing is described. A scanner is described which acquires images of the dentition which are converted to three-dimensional frames of data. The data from the several frames are registered to each other to provide a complete three-dimensional virtual model of the dentition. Individual tooth objects are obtained from the virtual model. A computer-interactive software program provides for treatment planning, diagnosis and appliance from the virtual tooth models. A desired occlusion for the patient is obtained from the treatment planning software. The virtual model of the desired occlusion and the virtual model of the original dentition provide a base of information for custom manufacture of an orthodontic appliance.Type: GrantFiled: October 24, 2002Date of Patent: April 18, 2006Assignee: Orametrix, Inc.Inventors: Rüdger Rubbert, Thomas Weise, Friedrich Riemeier, Rohit Sachdeva, Werner Butscher, Peer Sporbert, Hans Imgrund, Lutz Pfeil, Hans-Florian Geerdes, Dimitrij Kouzian, Mario Leichner, Stephan Maetzel, Peter See, Jens Troeger

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
