In one embodiment, the treatment may encompass orthodontic treatment. Similarly, surgical treatment plans can be created. Data is extracted from the virtual patient model or simulations thereof for purposes of manufacture of customized therapeutic devices for any component of the craniofacial structures, e.g., orthodontic appliances.Type: GrantFiled: May 1, 2007Date of Patent: February 14, 2012Assignee: Orametrix, Inc.Inventors: Rohit Sachdeva, Sanjeev Taneja, Peer Sporbert, Phillip Getto, Stephan Maetzel, Hans Imgrund, Charles L.

Patent number: 8113830Abstract: An instrument for curing light-curable compounds that includes at least one light-emitting element operable for emitting light in a band of wavelengths and is capable of curing a light-curable compound. A control circuit controls the operation of the light-emitting element. The control circuit is operable for providing a power signal to the light-emitting element at a steady state power level to drive the element to emit a steady state light output. The control circuit, while continuing with a power signal at the steady state power level, is further operable to provide temporary micro-pulses in the power signal to temporarily provide an increased power level to the light-emitting element above the steady state power level before returning to the steady state power level, to thereby increase the light output of the instrument while controlling heat generated thereby.Type: GrantFiled: May 27, 2005Date of Patent: February 14, 2012Assignee: Kerr CorporationInventors: Owen J. Gill, Denis J. Lachance

Patent number: 8113832Abstract: According to one broad aspect of one embodiment of the present invention, disclosed herein is a hand held oral irrigation device having a tip for dispensing fluids. In one example, an oral irrigation device includes a body portion, and a reservoir for storing fluids, wherein the body and/or the reservoir define a first major diameter at a lower end of the oral irrigation device, and define a second major diameter at an upper end of the oral irrigation device, the first major diameter being larger than the second major diameter. In this example, by providing such a geometry for the device, a user can grasp the device with one hand about the second major diameter during use. In another example, the body includes a pump for pumping fluids from the reservoir to the tip, wherein the pump includes an inlet valve and an outlet valve, the inlet valve including a reed valve made of flexible fabric material. The outlet valve may also include a reed valve made of flexible fabric material.Type: GrantFiled: December 11, 2006Date of Patent: February 14, 2012Assignee: Water Pik, Inc.Inventors: Clifford J. Snyder, Gary L. Sokol, Roberta L. Callaghan

Patent number: 8113833Abstract: The shank (12) of a disposable rotary cutting tool (10) comprises a pipe section (16) cut from a drawn metal pipe. The tool head (14) is formed from a cut-out (18a, 18b) of a drawn metal sheet or a section of a metal tube by non-cutting machining. The pipe section (16) and the tool head (14) are advantageously attached by force fitting.Type: GrantFiled: April 6, 2009Date of Patent: February 14, 2012Assignee: Straumann Holding, AGInventor: Stephane Courvoisier

Patent number: 8113834Abstract: Two or more implants (8, 9, 10) are arranged in succession in the jaw bone (1) and bear or comprise growth-stimulating substances (25), here called GSS, which, as a function of secretion of body fluid at the implants, are intended to be released and form new bone (11-15) around the implants. The implants are designed to work with a release process for GSS, permitting a leveling-out effect along the extent of the jaw bone in the horizontal and/or vertical direction and/or a level-raising effect in the vertical direction. In this way it is possible to achieve optimum positions for the implants without the risk of reduced stability and/or compromised esthetics.Type: GrantFiled: May 23, 2008Date of Patent: February 14, 2012Assignee: Nobel Biocare AB (Publ)Inventor: Jan Hall

Patent number: 8113839Abstract: An image and motion corresponding to the image are presented in response to a request issued by an user. The user transmits image data from a terminal to a motion data generating apparatus. The motion data generating apparatus generates motion data from the received image data. The motion data generating apparatus transmits the generated motion data together with the image data, in a mutually related fashion, to an image/motion control apparatus. The motion data generating apparatus also transmits ID data assigned to the image data and the motion data to the terminal. The image/motion control apparatus stores the received data. When the image/motion control apparatus receives ID data input by a user via an image/motion presenting apparatus, the image/motion control apparatus reads image data and motion data corresponding to the received ID data and transmits the image data and the motion data to the image/motion presenting apparatus.Type: GrantFiled: July 20, 2001Date of Patent: February 14, 2012Assignee: Sony CorporationInventors: Tetsushi Kokubo, Kazuyuki Marukawa, Yasuhiro Yukawa
