Patent number: 7740476Abstract: 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: GrantFiled: May 19, 2006Date of Patent: June 22, 2010Assignee: Orametrix, Inc.Inventors: Rüdger Rubbert, Thomas Weise, Peer Sporbert, Hans Imgrund, Mario Leichner, Rohit Sachdeva

Publication number: 20100153075Abstract: A method and system are disclosed for finding virtual tooth features on virtual three-dimensional models of the teeth of patients. The tooth features comprise marginal ridges, cusp tips, contact points, central groove and buccal groove. Tooth axes system plays a key role in identifying the tooth features. An iterative method is disclosed for improving the accuracy of the tooth axes system. A virtual three-dimension model preferably obtained by scanning the dentition of a patient forms the basis for determining the tooth features. Tooth features are derived for all categories of teeth including molars, premolars, canines and front teeth. Tooth features are very helpful and used in planning orthodontic treatment. The tooth features are determined automatically using the computerized techniques; and can be manually adjusted when necessary.Type: ApplicationFiled: February 25, 2010Publication date: June 17, 2010Inventors: Peer Sporbert, Hans Imgrund, Markus Kaufmann

Patent number: 7585172Abstract: 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: October 9, 2003Date of Patent: September 8, 2009Assignee: Orametrix, Inc.Inventors: Rüdger Rubbert, Thomas Weise, Rohit Sachdeva, Hans Imgrund, Peer Sporbert, Mario Leichner, Jens Troeger, Dimitrij Kouzian, Stephan Maetzel

Publication number: 20090220918Abstract: A method is provided for automatically separating tooth crowns and gingival tissue in a virtual three-dimensional model of teeth and associated anatomical structures. The method orients the model with reference to a plane and automatically determines local maxima of the model and areas bounded by the local maxima. The method automatically determines saddle points between the local maxima in the model, the saddle points corresponding to boundaries between teeth. The method further positions the saddle points along a dental arch form. For each tooth, the method automatically identifies a line or path along the surface of the model linking the saddle points to each other, the path marking a transition between teeth and gingival tissue and between adjacent teeth in the model. The areas bounded by the lines correspond to the tooth crowns; the remainder of the model constitutes the gingival tissue.Type: ApplicationFiled: May 11, 2009Publication date: September 3, 2009Inventors: Markus Kaufmann, Peer Sporbert, Phillip Getto

Patent number: 7471821Abstract: 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: GrantFiled: May 1, 2002Date of Patent: December 30, 2008Assignee: OraMetrix, Inc.Inventors: Rüdger Rubbert, Hans Imgrund, Peer Sporbert, Stephan Maetzel, Thomas Weise

Patent number: 7458812Abstract: 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: March 8, 2005Date of Patent: December 2, 2008Assignee: Orametrix, Inc.Inventors: Peer Sporbert, Hans Imgrund, Dimitij Kouzian, Stephan Maetzel, Rohit Sachdeva, Rüdger Rubbert
