| 122 | Z-bend orthodontic instrument and method | US09521764 | 2000-03-09 | US06293791B1 | 2001-09-25 | Martin Weinstein |
| An orthodontic instrument includes a pair of complementary mating die movable together and apart for forming a Z-shaped bend in an orthodontic arch wire. A Z-shaped bend in an orthodontic arch wire is utilized in conjunction with an orthodontic appliance for applying force to a tooth through a bracket thereon to change its inclination and/or rotation respecting the long axis of the tooth, e.g., to upright an angulated tooth or derotate a rotated tooth. Different embodiments of the instrument are utilized in a sideways or an end-on orientation relative to the arch wire to form a Z-bend therein in situ in a patient's mouth, or may operate on the arch wire outside the mouth. | ||||||
| 123 | Heated orthodontic pliers | US09250271 | 1999-02-16 | US06293790B1 | 2001-09-25 | J. Keith Hilliard |
| Orthodontic pliers comprised of two asymmetrical components that are subapically and pivotally joined in a first main embodiment. Each of these elongate pieces is irregular in shape, unequal in length and the jaws are asymmetrical jaws relative to each other. The pliers when heated are used for producing or modifying bumps on a thermoplastic retainer. One of the jaws has a throughbore or blind bore for receiving the bump forming end of the other jaw. The jaw with the bump forming end is shorter and curvilinear so that the only part of that jaw that comes in contact with the retainer is the bump forming end. Additionally, the bump forming end may be of different shapes in order to produce different shaped bumps such as ramps, logos, logo pockets, fluoride pockets, bite plates, rectangular shapes for the retention of blocks to be wired, and hooks for elastic banding, depending on the needs of the individual patients. The pliers are heated to a temperature range of approximately 325° F. to 350° F., or the appropriate temperature for a specific thermoplastic material, to facilitate the formation of the bump in the thermoplastic retainer. A second main embodiment includes a system of pliers with jaws of equal and symmetrical shape for crimping a warmed retainer having an encapsulated expansion screw. | ||||||
| 124 | Method and apparatus for removing bonded dental appliances | US09526740 | 2000-03-16 | US06280184B1 | 2001-08-28 | David C. Hamilton |
| An orthodontic onlay having a mesial and distal sections is debonded from multiple teeth by positioning a plier-type debonding apparatus having a first and a second lever arms pivotally connected for rotation relative to each other and having respectively a first and a second handle portions, a hook extending from said second jaw portion, and a bracing platform pivotally connected to said first jaw portion and facing the hook.

| 125 | Method of fabricating metal instruments from raw material and orthodontic pliers made thereby | US294653 | 1994-08-23 | US5588832A | 1996-12-31 | Farrokh Farzin-Nia |
| Corrosion resistant instruments such as those used in medicine and dentistry are efficiently made from raw materials that are difficult to machine. Round bar stock is rolled or otherwise deformed to have flat sides and rounded edges. The parts of the instrument are cut from the flattened bar, by combinations of transverse and longitudinal cuts, so that the rounded edges of the bar define the shape of convexly curved finish surfaces of the instrument. Expensive machining steps are eliminated. An orthodontic pliers is particularly disclosed, made according to the method, by making one or more Z-shaped cuts that preserve the rounded sides to define the outer surfaces of a handle and opposing jaw on each of two plier parts, pivotally joined together. | ||||||
| 126 | Rotatably driven autoclavable ligation instrument | US408213 | 1995-03-22 | US5542843A | 1996-08-06 | Michael T. Price |
| An autoclavable ligation instrument for use in dental or medical applications which includes a ligature gripping tool having a pair of jaws with handle members connected thereto, and a drive mechanism for causing rotational movement of the gripping tool for consequent twisting of opposite ends of a ligature being gripped thereby. The drive mechanism includes a spring biased helically shaped drive shaft which is engaged by a drive follower nut that is connected to the gripping tool, such that activation of the drive mechanism causes the drive follower nut, and consequently the gripping tool, to rotate about the helically shaped drive shaft. The gripping tool includes a releasable locking mechanism for locking the jaws of the gripping tool in their closed position, and the gripping tool and drive mechanism are disassemblable and constructed of an autoclavable material to facilitate sterilization thereof. | ||||||
| 127 | Dental instrument | US311883 | 1994-09-26 | US5538421A | 1996-07-23 | Thomas E. Aspel |
| A dental instrument is provided comprising a first member having a first handle opposite a first jaw and a second member having a second handle and a second jaw. The first jaw is longer than the second jaw, and both jaws have inner surfaces. The first member is pivotally connected to the second member such that the first handle opposes the second handle and the first jaw opposes the second jaw. Movement of the first handle and the second handle correspondingly cause movement of the first jaw and the second jaw. The inner surface of one of the jaws is disposed within an acute angle of the centerline of the instrument. The inner surface of the other jaw is disposed at the acute angle from the disposed jaw. | ||||||
| 128 | Ligature tying instrument | US250104 | 1981-04-02 | US4392494A | 1983-07-12 | Richard L. Ashby |
| This patent describes a new orthodontic instrument to be used for tying or twisting the ligature wires used to hold the arch wire to the bracket. It also explains the method of use which consists of: twisting the wires, after the ligature wire has been placed on the bracket; tucking the twisted end out of the way; and then breaking the end at the tip of the instrument. The instrument replaces three instruments normally used, by improvements in jaw design to facilitate grasping and centering the wires for spinning, balancing the instrument by general symmetry, and the addition of an extension handle to allow rapid spinning, and tucking of the wire ends as they are broken in a controlled manner, and at a specific place. The instrument thus simplifies, speeds and further improves the application of ligature wires. | ||||||
