  • Patent number: 10117729
    Abstract: A method for treating orthodontitis (i.e., gingivitis caused by malpositioned teeth). The process includes evaluating improper morphologies of alveolar bone in the horizontal dimension (i.e., orthodontosis) caused by displaced root(s) of a tooth, uprighting the root of the malpositioned tooth utilizing an orthodontic bracket system thereby causing the alveolar bone to be restored, which in-turn alleviates the orthodontitis. An orthodontic bracket is provided for use with an arch wire to apply corrective forces to a tooth. The bracket includes a vertical member having a slot formed therein for receiving the arch wire and a wide base horizontal member connected to the vertical member. The vertical member is positioned gingivally with respect to the horizontal member.

  • Patent number: 9149344
    Abstract: The appliance of the present invention is a customized wire device for orthodontic alignment of the mal-aligned teeth. The final position and orientation of the brackets are assessed by simulating the desired aligned stage. Once the final position and orientation of the brackets is known from the simulated aligned stage, this bracket position and orientation is preserved by passing a wire passively through these brackets at the desired aligned stage. This passive wire essentially forms a template of final aligned stage; when securely engaged in the brackets on the mal-aligned stage this wire needs to be deflected and generates forces that align the teeth to its designed aligned stage due to elastic recoil of the wire.

  • Patent number: 9119693
    Abstract: This invention is an adjustable orthodontic bracket system which allows brackets to be adjusted for the particular angulations required for each individual tooth of any patient, while continuously attached to the tooth surface. The orthodontist manually adjusts the relationship of the bracket component with the frame and bracket base during treatment eliminating the necessity of repositioning bracket components due to erroneous positioning. The bracket component is positioned such that it can move completely in all directions to achieve the proper angulation for tooth repositioning. The base of the bracket component and the interior surface of the bracket compartment are textured to provide friction and secure the components once positioned for proper tooth movement. The exterior of the bracket component is also textured to provide more secure attachment to the surface of the tooth. This system will lead to lower treatment cost and quicker adjustments of the orthodontic bracket system.

  • Patent number: 8931171
    Abstract: A green metal body includes metal particles and a binder in the shape of an orthodontic bracket and/or base plate. The green metal body is fabricated by being laser-cut with a laser to shape the green metal body into the shape of an orthodontic bracket and/or to carve recesses and/or undercuts into the bonding surface of the bracket. The green metal body is sintered to shrink its volume into a denser and less porous sintered metal body configured to be an orthodontic bracket. The resultant sintered orthodontic bracket includes recesses and/or undercuts in the bonding surface to provide a mechanical aspect when bonded to a tooth.

    Abstract: A subject of the invention relates to providing a powder for a translucent zirconia sintered body which is necessary for the production of a zirconia sintered body having a high sintered-body density and high strength and giving an excellent sense of translucency, without conducting any special sintering, such as HIP sintering. The invention relates to a technique for obtaining, through normal-pressure sintering, a translucent zirconia sintered body characterized by comprising zirconia which contains 2-4 mol % yttria as a stabilizer and has an alumina content of 0.2 wt % or lower, and by having a relative density of 99.8% or higher and a total light transmittance, as measured at a thickness of 1.0 mm, of 35% or higher. It is preferred that a powder containing 0-0.2 wt % alumina with a particle diameter of 0.01-0.5 ?m, having a BET specific surface area of 5-16 m2/g and an average particle diameter of 0.3-0.7 ?m, and having a rate of sintering shrinkage in normal-pressure sintering (??/?T; g/cm3·° C.) of 0.

    Abstract: A curable orthodontic FFM resin rope appliance connecting orthodontic anchoring and custom appliances affixed to teeth, TADs and/or tooth positioning appliances, which serve in moving and stabilization if teeth by connecting said appliances and/or orthodontic auxiliaries. The FFM resin rope appliance is moldable and adaptable to the oral cavity and positioned to be secured between any type of fasteners including mechanical fasteners, which accept the FFM resin rope in an uncured first mode where the FFM resin rope is cut to length, positioned around the anatomy of the mouth and attached to clamps or fasteners and/or flex fit wafers FFW(s) at each or one end. Once connected together the FFM resin rope is cured and becomes a solid entity ready to accept orthodontic forces to hold or move teeth.

  • Patent number: 8875873
    Abstract: Orthodontic assemblies and related methods are provided where an adhesive coated orthodontic appliance is received in a container that includes a substrate and a lid having a retaining member. When the lid is closed, the retaining member is complemental to the shape of the appliance and engages with the appliance. By conforming to the shape of the appliance, the retaining member constrains the appliance from shifting in lateral and vertical directions within the container. When the lid is opened, the associated retaining member disengages from the appliance, thereby facilitating user access to the appliance.

  • Publication number: 20140272749
    Abstract: Provided are orthodontic appliances and related methods in which at least one region of at least one sidewall of an archwire slot is tapered relative to an opposing sidewall. This feature can allow the archwire slot to conform to the slight twist that occurs in the archwire when the archwire is placed in asymmetric torque. Advantageously, this feature can distribute the contact stress between the archwire and appliance over a much larger surface area compared with conventional appliances, leading to a dramatic and surprising increase in torque strength and providing other ancillary benefits.

  • Publication number: 20140212827
    Abstract: Orthodontic appliances and related methods are provided, including a fast-dissolving and humidity-resistant coating, containing a colorant and a binder selected from a polyamide, cellulose derivative, or homopolymer/copolymer of poly(ethylene oxide). The coating can facilitate appliance identification and serve as a reference marking to assist the practitioner in appliance placement. Advantageously, the composition of these coatings allows the color marking to be rinsed off quickly, and yet the color of the coating does not bleed during storage even in high humidity environments. The fast-dissolving nature of these coatings also allows the coating to be deposited in concave and recessed areas of the appliance, such as the archwire slot and vertical slot, since these coatings can be removed prior to archwire installation.
