Patent number: 9466151Abstract: A method and workstation are described for designing compensation in an orthodontic archwire in order to offset the bracket-slot-to-wire play and realize the disered displacement in a tooth from an initial position to the target position. Bracket-slot-to-wire play can reduce the effectiveness of an archwire in bringing the teeth of an orthodontic patient from malocclusion to desired target. Bracket-slot-to-wire play is the difference in volume between the size of a bracket slot, which is larger than the size of the archwire, and the size of the sliding segment of an archwire inserted in the bracket slot. Customized archwires comprise alternating sliding segments interconnected by segments with bends and/or twists in three-dimensional space. The sliding segments are placed in the bracket slots and exert forces on the brackets created by the segments with bends and/or twists for moving the teeth towards the target positions.Type: GrantFiled: April 30, 2010Date of Patent: October 11, 2016Assignee: ORAMETRIX, INC.Inventors: Phillip Getto, Rohit Sachdeva, Peer Sporbert, Dimitij Kouzian

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: 8192197Abstract: 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: GrantFiled: October 26, 2009Date of Patent: June 5, 2012Assignee: Orametrix, Inc.Inventors: Peer Sporbert, Dimitij Kouzian, Hans Imgrund, Stephan Maetzel
