Patent number: 11801123Abstract: In a preferred embodiment of the disclosure, tooth attachment placement (TAP) device or for assisting a user in placing one or more appliances or attachments on one or more teeth is disclosed. The TAP device comprises single tooth jigs connected through splines. The geometry of the device is automatically designed in the treatment planning unified workstation, thereby generating a digital STL file. Then the device is created from a non-flexible biocompatible material by a 3D printer in accordance with the digital STL file. Appliance, for example, may be a bracket or a bracket shim; and the attachment may be an aligner attachment or a pad. Different embodiments of the TAP device are disclosed. Methods for verifying the accuracy of the placements of the brackets on the teeth using the TAP device are disclosed.Type: GrantFiled: November 20, 2020Date of Patent: October 31, 2023Assignee: DENTSPLY SIRONA INC.Inventors: Frank Witte, Friedrich Riemeier, Rohit Sachdeva, Phillip Getto

Publication number: 20160228214Abstract: In a preferred embodiment of the invention, an interface attachment device which is customized on one side for placement on a patient's tooth surface and locked on to the bottom or base of a bracket on the other side is disclosed. The combination of the interface attachment device and the bracket is bonded to the surface of a tooth for an orthodontic treatment of the patient. One or more interface attachment devices, with or without brackets, can be precisely placed and bonded to the corresponding surfaces of one or more teeth of a patient using a tooth attachment placement device created for the patient. The locking mechanism between the interface attachment and the bracket can be (a) form-locked, i.e. male/female arrangement, (b) friction-locked (i.e. using spring, magnetism, shape memory phase shift, shrinkage, etc.), (c) combination of (a) and (b), or (d) any other type. The interface attachment can be attached to the tooth surface by any kind of adhesive or composite material.Type: ApplicationFiled: February 11, 2016Publication date: August 11, 2016Applicant: ORAMETRIX, INC.Inventors: Rohit Sachdeva, Frank Witte, Friedrich Riemeier

Patent number: 8121718Abstract: 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: July 28, 2009Date of Patent: February 21, 2012Assignee: 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

Patent number: 8082769Abstract: A robotic bending apparatus for bending archwires and other types of elongate, bendable medical devices into a desired configuration includes a first gripping tool and a moveable gripping tool. The first gripping tool can be either fixed with respect to a base or table for the robot or positioned at the end of robot am. The moveable gripping tool is mounted to the end of a moveable robot arm having a proximal portion also mounted to the base. The robot preferably comprises a six axis bending robot, in which the distal end of the moveable arm can move relative to the fixed gripping tool about three translational axes and three rotational axes. The gripping tools preferably incorporate force sensors which are used to determine overbends needed to get the desired final shape of the archwire. The robot may also include a resistive heating system in which current flows through the wire while the wire is held in a bent condition to heat the wire and thereby retain the bent shape of the wire.Type: GrantFiled: September 14, 2007Date of Patent: December 27, 2011Assignee: Orametrix, Inc.Inventors: Werner Butscher, Friedrich Riemeier, Rüdger Rubbert, Thomas Weise, Rohit Sachdeva
