    摘要: An orthodontic appliance such as a bracket or buccal tube has an overall, low profile shape. The appliance includes a base having a thickness that is less in regions adjacent the archwire slot as compared to remaining regions. In certain embodiments, the base is provided with protrusions that extend into the archwire slot for controlling rotation of the associated tooth. The resulting low profile of the appliance enhances its aesthetic appearance and helps to avoid impingement of the appliance and the attached archwire on adjacent soft tissue in the oral cavity.

    摘要: A completely corrosion resistant, high strength cutting tool such as an orthodontic wire cutter includes a stainless steel body having a pair of corrosion resistant alloy steel bonding tips brazed thereto. The tips are brazed to the body using a nickel alloy brazing foil at a brazing temperature of approximately 1900 degrees F. After a rough grinding to appropriate shape, the entire tool is heat treated in a process that heats the tool to an austenitizing temperature for the cutting tips that is about 2050 degrees F. and substantially above the brazing temperature to achieve a tip hardness of 62-67 Rc. Thereafter finish grinding, buffing, polishing and honing of the cutting edges completes the manufacture of the cutting tool.

    摘要: An orthodontic bracket or similar orthodontic appliance is made of a polycrystalline ceramic having a translucency which minimizes visibility of the appliance when mounted on a tooth. The ceramic is formed by pressing a powder material, such as high purity aluminum oxide, and sintering to yield a single phase appliance having substantially zero porosity and an average grain size preferably in the range of 10 to 30 microns. The substantially color-free ceramic appliance has desirable strength and other mechanical properties combined with a translucency which permits the natural color of the tooth to diffusely show through in a fashion tending to make the appliance blend with and disappear against the tooth.

    摘要: An orthodontic appliance such as a bracket or buccal tube has a latch for retaining an archwire in an archwire slot. The latch releases the archwire from the archwire slot whenever the archwire exerts a force in a generally buccolabial direction on the appliance that exceeds a certain minimum value. The minimum value is less than about one-half of the force required in the same direction to debond the appliance from the tooth, and thus reduces the likelihood that the appliance will unintentionally debond from the tooth during the course of orthodontic treatment.

    摘要: An orthodontic assembly includes one or more orthodontic brackets that are releasably received in a tubular carrier. The carrier has arms with outer end sections that are spaced apart from each other to present a channel therebetween. The outer end sections of the arms are received in occlusal and gingival recesses of each bracket in order to support the bracket in suspended relation. The carrier is particularly useful for holding brackets during a manufacturing operation or during transport of the brackets from manufacturing operation to another. The carrier is also useful for supporting brackets in a package for shipment to the end user, especially when the brackets are precoated with a layer of adhesive.

    摘要: An orthodontic appliance that is adapted for bonding directly to the enamel surface of a patient's tooth has structure for enhancing placement of the appliance on the tooth surface. The structure facilitates gripping the appliance by a hand instrument so that the appliance does not unduly shift or rock during a bonding procedure. In certain aspects of the invention, the placement enhancement structure comprises one or more protrusions located along sides of the appliance, and optionally some of the protrusions are located within a recess that extends along an occlusal or gingival side of the appliance.

    摘要: An orthodontic bracket assembly includes a bracket and latch coupled to the bracket. The latch is movable between a slot-open position to enable removal or insertion of an archwire in an archwire slot of the bracket, and a slot-closed position to retain the archwire in the archwire slot. The latch includes a first portion that is received in a passage that extends in a generally occlusal-gingival direction through a body of the bracket, and a second portion that is received lingually of at least one bracket tiewing when the latch is in the slot-closed position.
