Publication number: 20150140504Abstract: In dentistry very often soft tissue has to be cut. It has become customary to cut soft tissue, in particular gum or gingiva, or to disinfect pockets in the gingiva that exist at the neck of teeth with the help of laser light. The same applies to a disinfection of the channel in the root of teeth (endodontic treatment). Prior art concepts of cutting soft tissue rely on the use of red or infrared diode lasers and lead to an excessive heating the tissue and damaging of surrounding tissue. We suggest a device for treatment comprising a laser diode with a wavelength of 445±15 nm, in particular 445±10 nm, for providing the laser light. The use of e.g. 445 nm for cutting soft tissues has numerous advantages.Type: ApplicationFiled: November 18, 2014Publication date: May 21, 2015Inventors: Ralf SUTTER, Bernd Oehme, Thomas Jerger, Francesco Zanata

Publication number: 20150056567Abstract: A device and method of using a device for photon-induced endodontic and periodontic applications includes a power source, a trigger coupled to the power source and circuit elements initiated by the trigger. The circuit elements include a timing circuit and a driver. A light source is coupled to the circuitry elements wherein and driver controls the period, cycle, and pulse generation of the light source to create photon induced acoustic waves. The optical assembly includes a fiber optic cable and an output tip and is coupled to the light source. This optical assembly refracts light from the light source and photon induced acoustic waves exit the output tip in a pre-determined pattern.Type: ApplicationFiled: November 29, 2012Publication date: February 26, 2015Applicant: AMERICAN EAGLE INSTRUMENTS, INC.Inventors: Gilbert Fregoso, Brad B.

Publication number: 20150050613Abstract: A dental syringe tip system for attachment to a dental syringe. The dental syringe tip system can include components such as an outer core, an inner core, and a carrier which can be combined in a multitude of combinations to achieve different fluid flow characteristics, such as discharge pressure and discharge pattern, through the dental syringe tip. The outer core and inner core can have passages designed to modify fluid flow characteristics. In addition, the outer core and inner core can have additional connectors for receiving fluids from sources other than a dental syringe. Some or all of the components can be separate to be assembled by a manufacturer or an end-user. Assembly of multiple components can be facilitated by retention features located on the components.Type: ApplicationFiled: August 13, 2014Publication date: February 19, 2015Inventor: Donovan Winston Berkely

Patent number: 8948482Abstract: The present disclosure provides computing device implemented methods, computing device readable media, and systems for motion compensation in a three dimensional scan. Motion compensation can include receiving three-dimensional (3D) scans of a dentition, estimating a motion trajectory from one scan to another, and calculating a corrected scan by compensating for the motion trajectory. Estimating the motion trajectory can include one or more of: registering a scan to another scan and determining whether an amount of movement between the scans is within a registration threshold; determining an optical flow based on local motion between consecutive two-dimensional (2D) images taken during the scan, estimating and improving a motion trajectory of a point in the scan using the optical flow; and estimating an amount of motion of a 3D scanner during the scan as a rigid body transformation based on input from a position tracking device.Type: GrantFiled: November 1, 2012Date of Patent: February 3, 2015Assignee: Align Technology, Inc.Inventor: Adi Levin

Patent number: 8944813Abstract: The oral health appliance (10) includes a source of light (16) having a wavelength which is suitable for determination of oral health conditions, as well as treatment thereof. An assembly (16) in the appliance directs the light to selected dental regions of the mouth. A light receiver and sensor (16) receives reflected light from the dental regions, produces signal information therefrom and delivers the signal information to a processor (20), which determines the presence of oral health conditions, as well as determining the overall coverage of the mouth during a use of the appliance. The information from the processor is then sent to a display (24), identifying the presence of any oral health conditions and the location thereof, as well as information concerning those areas of the mouth which have been investigated during the use of the appliance and those which have not.Type: GrantFiled: August 12, 2009Date of Patent: February 3, 2015Assignee: Koninklijke Philips N.V.Inventor: Garrett Kotlarchik
