Publication number: 20090081602Abstract: An automatic Maxillary Expander, which is a bone-borne distractor for expanding the maxillary bone in adult and adolescents having transversal maxillary hypoplasia. It fixes itself to the palatal vault in a way without any need for screwing, by the asymmetrical triangular prism-shaped spikes on the anterior, posterior columns. Both being hygienic and not wasting a bulky space in the mouth, it provides a high patient comfort. The maxillary expanding process does not interrupt orthodontic treatment of patients and minimizes damage to the texture of the mouth. An automatic Maxillary Expander Transferring Apparatus enables the practitioner to place the Automatic Maxillary Expander into the palatal surface with ease and precision into the palate under local anesthesia quickly, without any surgical operation. In addition, this apparatus is composed of a very simple mechanism. It has rounded ends in order not to hurt the practitioner or patient.Type: ApplicationFiled: April 10, 2007Publication date: March 26, 2009Inventor: Mustafa Ayan

Patent number: 7500851Abstract: An orthodontic arch expander joins to a mouthpiece proximate to the rear of the mouthpiece. The transparent mouthpiece has a desired arc that fits over the teeth of the upper jaw. The mouthpiece has two wings that join near the incisors and then become parallel and spaced apart around the molars. Near the molars, an arch expander joins to the mouth piece. The arch expander has two telescoping shells with a threaded jack and cooperating springs. Each shell joins to a corresponding wing of the mouthpiece. Turning the jack lengthens a rod that pushes the shells outwards against the mouthpiece thus widening the maxillary arch without brackets or bands upon the teeth. An alternate embodiment has the arch expander attaching directly to the palatal bone through screws placed through a grommet at the end of each shell by an orthodontist or oral surgeon.Type: GrantFiled: July 1, 2006Date of Patent: March 10, 2009Inventor: Michael O. Williams

Publication number: 20090042158Abstract: The present invention relates to a method of treating bone loss in the posterior maxilla. Adequate bone is required in the posterior maxilla to facilitate tooth replacement with dental implants. The Lateral wall of the maxilla is exposed and an osteotomy is performed to expose the sinus membrane. Pneumatic pressure is utilized to detach the membrane from the lateral wall of the sinus. Once detached fluid bone graft material is injected between the bone of the maxilla and the sinus membrane thereby lifting the membrane with hydraulic pressure. The combination of pneumatic pressure to detach the membrane and hydraulic pressure to create a void for grafting material presents numerous benefits to the patient and surgeon.Type: ApplicationFiled: August 9, 2007Publication date: February 12, 2009Inventor: Gregory Gene Steiner

Publication number: 20090029309Abstract: An orthodontic force mechanism includes a jack screw having a pair of ends, at least one of which is threaded, and a central spindle between the ends, which spindle has two intersecting radial through-holes therein. A pair of nut housings are mounted on the end portions of the jack screw, at least one of which is threadedly coupled to a threaded end portion of the jack screw. A lock mechanism mounted on the central spindle section includes a spring-loaded detent configured to engage an end opening of each of the through holes in the spindle when the through hole is in alignment with the detent, such that the spindle cannot rotate relative to the lock mechanism when the detent is inserted into a through hole. The detent can be moved out of engagement with a through hole using a tool inserted into that through hole from its opposite end.Type: ApplicationFiled: June 9, 2008Publication date: January 29, 2009Inventor: Stephen D. Hanks

Patent number: 7451767Abstract: A dental oral appliance for use with patients who suffer with sleep disorders, to reduce or eliminate snoring and to open the airway for a sleeping individual who suffers with obstructive sleep apnea. The appliance covers the inside (lingual) of the upper teeth and has an open palate. Retention for the appliance is provided by either clasps placed over the upper right and left molars and a retainer in the anterior area or by an occlusal coverge of the upper teeth. A raised incisor ramp that extends from the incisal tip (biting edge) of the incisors toward the lingual, or posterior raised ramps, separate the posterior teeth to reduce spasm on the temporalis muscle. A transverse, transpalatal ramp, which extends from the inside (lingual) of the upper right molars to the inside of the upper left molars, covers the tongue and holds it down, opening the airway.Type: GrantFiled: June 23, 2005Date of Patent: November 18, 2008Inventor: Bryan Keropian

Publication number: 20080220388Abstract: An orthodontic appliance for distalizing opposed molars (2, 3) of the upper jaw of a patient, in which the device (4) has a bracing plate (5), which in its intended use rests on the palate of the patient, and which can be secured, via wire elements (6-9) disposed on the bracing plate (5), to opposed teeth (10-13) that are located anteriorly of the molars (2, 3) to be distalized. The appliance (4), with which the molars (2, 3) to be distalized can be moved individually backward as needed, includes a one-piece bracing plate (5), on the posterior end (14) of which two force modules (15, 16), spaced laterally apart from one another and adjustable independently of one another, are connected to the bracing plate, each being connectable via a respective elastic spring arm (17, 18) to one of the molars (2, 3) to be distalized.Type: ApplicationFiled: April 2, 2007Publication date: September 11, 2008Inventor: Klaus Weissbach Otte

Publication number: 20080176179Abstract: A dental apparatus is provided. Such dental apparatus includes two dental band members operably connected together at a predetermined location thereon for placement between two adjacent teeth of a patient. Such two dental band members are manufactured from a first predetermined material and have a first predetermined size and a first predetermined shape. Such dental apparatus also includes a mechanism for at least one of separating such two adjacent teeth of such patient and engaging such patient's teeth such that each dental band member sits closely adjacent a respective tooth of such patient in a manner conducive to a dentistry procedure including at least restorative dentistry.Type: ApplicationFiled: January 17, 2008Publication date: July 24, 2008Inventor: Paula Coffee

Publication number: 20080171300Abstract: The invention relates to an orthodontic expansion screw having two bodies whose distance from each other can be changed by means of a spindle that engages both bodies, whereby the spindle comprises an actuation part by means of which a torque can be effected for readjusting the spindle, and having straight-line guiding means that engage both bodies and guide them along two guide axes that are parallel to each other while preventing a relative rotation of the bodies when their distance from each other is being changed. The invention provides a friction brake that presses onto the actuation part of the spindle and thus generates a frictional force that renders a rotation of the spindle in both directions of rotation more difficult in order to prevent inadvertent readjustment of the spindle.Type: ApplicationFiled: December 20, 2007Publication date: July 17, 2008Inventor: Rolf Forster
