Publication number: 20140080090Abstract: A method and apparatus is disclosed for treating teeth associated with tooth structure removal and disinfection, in particular for endodontic procedures such as root canal tissue removal and decay treatment. Traditional methods involve the use of files, reamers, chemicals, drills, and burs, which have many disadvantages. The disclosed method and apparatus are based on the use of micro-tornado forces generated in a small working head attached to a dental hand piece and discharged from an extended cannula into a root canal orifice or a cavity to abrade, cut, and remove the content.Type: ApplicationFiled: September 17, 2013Publication date: March 20, 2014Inventor: Zohar Laufer

Publication number: 20140072932Abstract: In some embodiments, an apparatus comprises a housing, an emitter, and an electronic circuit. The housing is configured to fit within a patient's mouth. The emitter is at least partially encased within the housing. The emitter is configured to emit an effective amount of light to the alveolar soft tissue when the housing is disposed within the mouth. The electronic circuit is operatively coupled to the emitter. The electronic circuit is configured to control the emitter when the housing is disposed within the mouth and the apparatus is in use during orthodontic treatment. The apparatus and its use for regulating tooth movement or maintaining or improving oral tissue health are disclosed herein.Type: ApplicationFiled: April 19, 2013Publication date: March 13, 2014Inventors: Peter Brawn, Ryan Bredin, Timothy G. Shaughnessy, Kevin Strange, Paul Mathews

Patent number: 8670858Abstract: A tip-based computer controlled system for a dental delivery device is disclosed. The system automatically controls an operating characteristic such as power control or fluid flow based on tip identification and history. The operating characteristic may also be controlled in response to particular conditions throughout the dental procedure, such as (but not limited to) temperature, dental hygiene material, fluid type, etc. The system may provide an alert or shut off if unsafe conditions occur and/or error circumstances are detected. An operator interface is provided to configure the system and augment/override an executing control algorithm during a procedure. A method and a computer-readable storage medium are also disclosed.Type: GrantFiled: June 14, 2012Date of Patent: March 11, 2014Inventors: James Feine, Mohammad Ali Jamnia, William L. Bollig

Publication number: 20140065575Abstract: An apparatus for treatment of dental tissue has a first laser source optically connected to a first channel and the same first laser source optically connected to a second channel. The second laser source is optically connected to the first channel. That second laser source is designed to be pumped via the first channel by the diode laser to generate a power of radiation sufficient to cut hard dental tissue. The second channel is connected to a device for treatment of soft dental tissue and is designed to transmit radiation sufficient for treating soft dental tissue. The first laser source can be a diode laser designed to emit radiation of a wavelength selected from a range of 700 nm to 2700 nm. The second laser source can be a solid-state or fiber laser designed to emit a wavelength from a range of 2700 nm to 3000 nm.Type: ApplicationFiled: August 27, 2013Publication date: March 6, 2014Applicant: LASER ABRASIVE TECHNOLOGIES, LLCInventors: Gregory B.

Patent number: 8662890Abstract: A method for manufacturing a dental restoration for at least one section of a dental arch on the basis of digital overall data which are calculated in relation to individual data, which are based on three-dimensional optical individual measurements that are performed intra-orally of an area that contains at least one section of the dental arch. In order to ensure that the overall data, which have been received from individual measurements, represent the measured section of the dental arch and/or the dental arch in its entirety without any distortions, it is proposed that at least one area of the dental arch be measured together with a reference, which supplies three-dimensional information, and calculated from the individual data while considering the reference of the overall data.Type: GrantFiled: November 9, 2007Date of Patent: March 4, 2014Assignee: Degudent GmbHInventor: Thomas Ertl
