  • Publication number: 20180042700
    Abstract: An orthodontic bracket includes a bracket body and a ligating member. The ligating member retains an archwire in an archwire slot and includes archwire control structure including projecting portions spaced apart in a mesial-distal direction with a recessed area therebetween. The recessed area and the projecting portions overlie the archwire slot. The recessed area may include a flat or a curved surface in a mesial-distal direction. The recessed area and projecting portions may define a radius of curvature that is less than the radius of curvature of the archwire seated in the slot. The archwire contacts one or both the projecting portions resulting in a larger moment arm and better rotational control of the bracket with the force applied by the archwire.

  • Patent number: 9827073
    Abstract: A self-ligating orthodontic bracket for captivating an archwire with a tooth. The bracket includes a bracket body mountable to a tooth and a self-ligating mechanism having an archwire slot and a ligating slide. The ligating slide is movable between an open position in which an archwire is insertable into the archwire slot and a closed position in which the archwire is retained in the archwire slot. The bracket body may be formed from a non-metallic material, such as a polymer, a filled polymer composite, or a ceramic, and the self-ligating mechanism may be formed from a metal. The bracket may include a resilient engagement member with a detent positioned to engage an aperture or throughhole extending through the ligating slide when the ligating slide is in the closed position.

  • Patent number: 9717569
    Abstract: An orthodontic bracket for coupling an archwire with a tooth. The orthodontic bracket including a ceramic injection molded (CIM) bracket body including an archwire slot that is configured to receive the archwire therein. The CIM bracket body including a polycrystalline ceramic. A coating of alumina or silicon dioxide is in continuous and direct contact with at least the surfaces of the archwire slot. The orthodontic bracket is characterized by unexpectedly high torque strength. The ceramic injection molded (CIM) bracket body may include a polycrystalline ceramic having a grain size distribution characterized by an average grain size in the range of larger than 3.4 ?m to about 6 ?m such that the orthodontic bracket is also characterized by unexpectedly high fracture toughness. A method of making the orthodontic bracket includes injection molding a bracket using a ceramic powder, sintering the molded bracket, and coating the ceramic injection molded bracket.

  • Publication number: 20150017596
    Abstract: An adjustable orthodontic bracket is described which includes a body member having an orthodontic archwire fixing member and a first faying surface; a bonding base member having a second faying surface and a tooth bonding surface; and a connecting member that includes a layer of a thermoplastic polymer, and which connects the first faying surface of the body member to the second faying surface of the bonding base member. Methods of repositioning and manufacturing the adjustable orthodontic brackets are also described. A method is also provided for reducing a bond strength of an orthodontic appliance adhered to a tooth structure with a cured adhesive composition, which includes treating the orthodontic bracket with ultrasonic energy thereby reducing the bond strength more than about 20%. The cured adhesive composition includes an ultrasonic energy responsive filler, and under the ultrasonic energy stimulation, the cured adhesive composition softens thereby reducing the overall bonding strength.
