| 20080274435 | Crimping Pliers, Especially for Orthodontic Applications - Orthodontic crimping pliers include a first member having a first handle at a first end and a first jaw at a second end, the first jaw having a first flat edge, a second member having a second handle at a first end and a second jaw at a second end having a second flat edge and a pivot connecting the first and second members and allowing the first and second members to pivot with respect to one another so that pivoting the first handle towards the second handle causes the first jaw and the second jaw to move from an open position with the first and second jaws spaced apart toward a closed position with the first flat edge of the first jaw and second flat edge of the second jaw adjacent one another. In the closed position, the first flat edge of the first jaw and second flat edge of the second jaw are parallel and adjacent one another over a width of 0.005 to 0.015 inches. | 11-06-2008 |
| 20090253093 | Orthodontic Torque Pliers - The invention pertains to a tool or pliers for effecting a torque bends or twists to orthodontic rectangular arch wire. The pliers have two handles pivotally associated by a core, the core having a slot therein. One of the handles has a bifurcated head with the other handle having a single head adapted to fit within said bifurcated head and pivot on the core. The bifurcated headed handle has at least one slide reciprocally associated with a side of the bifurcated headed handle, the slide having a slot in an end thereof, the slide being manipulated so that its slot into aligned association with the slot in the core. The core is detachably secured to the single headed handle. Slots are in the single and bifurcated headed handles to access their bores so that all the slots can be aligned to accept an arch wire being passed through the slots in the handles and into the slots of the core and slide. Squeezing of the handles causes relative rotation between the core and slide to impart a twist to the wire. The degree of twist can be adjustably controlled. Preferably, there are two slides, one in each side of the bifurcated headed handle. | 10-08-2009 |
| 20090274988 | DEBONDING PLIERS - An instrument for debonding an orthodontic bracket from a tooth surface includes first and second plier portions coupled for relative pivotal movement. A lever arm pivotally movable relative to the first and second plier portions has a tooth engaging member on a first end. In one embodiment, the tooth engaging member is positioned on the lever arm for movement between a jaw of the plier portions and the tooth surface when a second end of the lever arm is pivotally manipulated in a direction toward a handle of the plier portions. In another embodiment, at least part of at least one plier portion is flexible relative to the lever arm such that the lever arm moves the tooth engaging member relative to a jaw of the plier portions after the bracket engaging portions are engaged with the orthodontic bracket and the handles and lever arm pivotally manipulated toward one another. | 11-05-2009 |
| 20100055633 | Crimping Machine, Method for Crimping a Tube on an Archwire Using Same and Method for Joining a Plurality of Archwire Segments Using Same - A crimping machine includes a platform having a substantially flat upper working surface and a first crimping jaw fixed on the platform. An arm is slidably attached to the platform, the arm having a second crimping jaw provided thereon, the arm being slidable at least between a first, crimping position in which the first and second jaws are opposed and adjacent one another and spaced apart by a first distance sufficient to crimp a workpiece between the first and second jaws, and a second, open position in which the first and second jaws are opposed and spaced apart by a second distance, the second distance being greater than the first distance and sufficient to insert an uncrimped workpiece therebetween. A resilient biasing element is provided for biasing the second jaw towards the first jaw. An actuator is provided for forcing the arm into the first, crimping position. | 03-04-2010 |
| 20100086889 | PLIERS FOR FORMING ORTHODONTIC WIRES - A pliers for forming orthodontic wires has opposing beaks with complementary wire-forming surfaces that include interfering portions. A hinge mechanism enables the beaks to open and close by rotating about an axis, and also allows a range of axial motion between the beaks sufficient to prevent interference between the wire-forming surfaces as the beaks are closed. By preventing such interference, novel over-bending capabilities can be achieved to form useful bending of low spring rate wire. A spring, such as a Belleville washer, exerts a biasing force parallel to the hinge axis to maintain alignment of the beaks, but allows the required range of axial motion between the beaks to prevent interference. | 04-08-2010 |
| 20100279244 | METHOD OF REMOVING AN ARCHWIRE FROM AN ORTHODONTIC BRACKET AND WIRE DISENGAGEMENT INSTRUMENTS FOR APPLYING SUCH METHOD - A method for removing an archwire from a slot of an orthodontic bracket having at least one retentive component involving creating a gap either between portions of a retentive component or between the retentive component and another component of the bracket and removing the archwire from the slot through the gap. The present invention is also directed to wire disengagement tools. Each tool includes a handle and a head portion which engages the retentive component. When the orthodontist applies a force, such as a rotational or plier-like motion, to the handle of the tool, the head portion exerts a force on the retentive portion to create a gap between portions of the retentive component or between the retentive component and another component of the orthodontic bracket. Each tool also includes a side arm, which lifts the archwire from the slot through the gap created by the head portion. | 11-04-2010 |
| 20110003263 | TWEEZERS FOR ORTHODONTIC LOCK - Tweezers including two manipulating arms with elastic elements that are terminated by two bits for gripping the lock also include: two projections facing one another, made on the two inside surfaces of the two bits, able to work in a removable manner, with adjustment, with two recesses opposite one another made on the two lateral surfaces of the lock, at least one extension that extends from a free end of at least one of the bits with an incline and over a suitable length at which the extension is able, when the tweezers are in use, to extend essentially parallel to the axis of the tooth in the direction of the occlusal surface, at least one return extending crosswise from a free end of at least one extension, able, when the tweezers are in use, to come to a stop on the occlusal surface of the tooth. | 01-06-2011 |
| 20110104629 | Apparatus and Method for Adjusting Orthodontic Wire - A handheld apparatus for adjusting orthodontic wire includes first and second handle portions and a jaw portion. The first handle portion pivotably couples to the second handle portion such that the first and second handle portions are capable of pivoting with respect to each other at a pivot axis. The jaw portion extends from the first and second handle portions. The jaw portion includes: a first prong extending from the first handle portion; and second and third prongs extending from the second handle portion. The second and third prongs each include: a respective inner surface that partially defines a slot between the second and third prongs; and first and second outer surfaces joined together by a transition region. | 05-05-2011 |
