  • Patent number: 7967602
    Abstract: 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.

  • Publication number: 20100279244
    Abstract: 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.

  • Patent number: 7258047
    Abstract: The present invention relates to a pliers that includes first and second arms that are pivotally interconnected utilizing an appropriate mechanical fastener. A spring is generally disposed about the mechanical fastener to bias the pliers toward an open condition. Further, a bearing is generally located between the first and second arms to hinder friction between the first and second arms, facilitate movement of the pliers between open and closed conditions, and provide some control for the range of pivotal motion of the first arm relative to the second arm.

  • Patent number: 7182595
    Abstract: A flush cutter of wires located on a patient's teeth has at least one pivotably carried cutting edge. An outer surface of the edge can be positioned adjacent to a surface from which the wire protrudes. An elastic insert or clamp, for griping cut wire ends, is carried adjacent to the edge. The insert has first and second spaced apart ends. A rigid surface is located to pivot toward the edge. The elastic clamp extends, in part, to the inner surface of the edge. As the cutting edge moves toward the rigid surface to cut the wire, the elastic clamp grips the cutoff wire end for removal. The rigid surface can be formed as a second cutting edge that moves toward the one cutting edge.

  • Patent number: 6910890
    Abstract: A dental pliers appliance and associated method for removing teeth from a patient's gum line and bone. First and second pivotally connected handles are provided, each including a user grasping portion. The first handle terminates in an arcuately extending jaw exhibiting a substantially pointed end, the second handle terminates in an opposing and offset support exhibiting a support surface with an ergonomic configuration substantially matching that of the patient's gum line. Upon aligning the support along a selected location below the gum line, and further aligning the jaw in abutting fashion against an inwardly facing side of a tooth, the offset support defining a center point of rotation proximate to an edge location of the gum line and bone. The handles are subsequently rotated in an outward fashion away from the patient's gum line to forcibly dislodge the tooth from the patient's gum line and bone.

  • Publication number: 20040219470
    Abstract: An orthodontic bracket comprises a bracket body, a base on the bracket body, and mechanical bonding structure on the base. An adhesive is applied to and mechanically bonded with the mechanical bonding structure to secure the bracket body and the base to a tooth. A portion of the base has a bond strength with the adhesive which is reduced relative to the bond strength between the remainder of the base and the adhesive. A debonding method includes applying a debonding force to the bracket at a first area of reduced adhesion between the bracket and the tooth, and removing the bracket from the tooth.
