Patent number: 8998608Abstract: 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: April 7, 2015Assignee: Orametrix, Inc.Inventors: Hans Imgrund, Rüdger Rubbert, Dimitij Kouzian, Peer Sporbert, Stephan Maetzel, Rohit Sachdeva

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
