Patent number: 8356603Abstract: In certain embodiments, an apparatus for treating a breathing condition includes a body, a threaded member, a hook, and a receiver. The body comprises a front stop, a rear stop, and a guide extending between the stops. The threaded member couples between the stops and rotates relative to the body. The hook couples to the guide, comprises a threaded passage and an arm that engages a lower arch, and travels in a forward direction along the guide to adjust the position of the lower arch. The receiver couples to the lower arch and comprises a shelf that engages the arm of the hook. The apparatus may include an extender coupled to the receiver and providing a shelf that is more rearward than the shelf of the receiver. The apparatus may include a post that couples the apparatus to another device.Type: GrantFiled: July 2, 2010Date of Patent: January 22, 2013Assignee: AirWay Technologies, LLCInventor: W.

Patent number: 8348663Abstract: A dental device (10) for temporarily filling a toothless gap (50) following extraction of a tooth. The dental device is arranged so as to be located in a space between two adjacent teeth (30, 40) bordering, on each opposed side, the toothless gap. The dental device comprises a central block (11) and two arms (12, 13) located on opposite sides of the central block (11). The two arms (12, 13) are extendible between a retracted position and an extended position. Each arm carries, at a free end thereof, at least one support (14, 15) adapted for resting respectively on a surface of the adjacent teeth when the arms are in the extended position. The central block includes an adjusting mechanism (19) for moving the two arms into the extended position, and a lock (20, 21, 22) locks the adjusting mechanism when the arms are in the extended position.Type: GrantFiled: October 30, 2009Date of Patent: January 8, 2013Assignee: Dynadent SarlInventors: Mahfoud Maadi, Abd-Al-Qadir Maadi, Karim Maadi

Publication number: 20120244487Abstract: A head positioning instrument is provided for accurately modeling the position of a patient's jaw for orthodontic treatment planning. The horizontal distance between a pair of reference points that are visible on an x-ray are measured. These reference points are then utilized to ensure that substantially true vertical and substantially true horizontal are reflected in a radiograph. The patient's lower jaw hinge is accurately located, and the upper jaw is located using a bite fork attached to the lower jaw hinge axis locator. The lower jaw hinge axis locator with the bite fork attached are removed from the head positioning instrument and transferred to an axis mounting stand for accurate reproduction. The patient's individual characteristics are accurately preserved throughout the transfer and modeling process, resulting in accurate correspondence between the model and radiograph.Type: ApplicationFiled: March 23, 2011Publication date: September 27, 2012Inventors: Ryan Tamburrino, Ken Tamburrino

Patent number: 8261748Abstract: A device for treating sleep apnea, the device comprising a tongue attachment member and a maxilla attachment subassembly. The tongue attachment member is fabricated having a sheath interlock member extending upward from a dorsal side of a sheath. The sheath is shaped to conform to a surface of an individual's tongue. A tongue receiving cavity is formed within the sheath, the cavity comprising an opening provided at a proximal end for receiving the individual's tongue. The sheath is referenced having a dorsal side and a ventral side. A sheath interlock member extends outward from the dorsal side. The maxilla tray is shaped to conform to and removably engage with an individual's upper dental arch. A tray interlock member extends from an interlock side of the maxilla tray and is positioned to interlock with the sheath interlock member, whereby the system extends an individual's tongue forward to treat sleep apnea.Type: GrantFiled: September 15, 2010Date of Patent: September 11, 2012Inventor: Howell Goldberg
