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

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

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: 9412166Abstract: A method and apparatus are disclosed enabling an orthodontist or a user to create an integrated three dimensional digital model of dentition and surrounding anatomy of an orthodontic patient from a three-dimensional digital model obtained using a scanner with a three-dimensional digital model obtained using a Cone Beam Computed Tomography (CBCT) or Magnetic Resonance Tomography (MRT) imaging devices. The digital data obtained from scanning as well as from CBCT imaging are downloaded into a computer workstation, and registered together in order to create a comprehensive 3-D model of the patient's teeth with roots, bones and soft tissues. The invention provides substantial improvement over the traditional two dimensional imaging modalities such as x-rays, photographs, cephalometric tracing for diagnosis and treatment planning.Type: GrantFiled: May 1, 2010Date of Patent: August 9, 2016Assignee: ORAMETRIX, INC.Inventors: Phillip Getto, Rohit Sachdeva, Peer Sporbert, Markus Kaufmann
