  • Patent number: 11382722
    Abstract: The present invention relates to orthodontic brackets designed for use with the deciduous teeth and method for its use. The brackets provide one or more debonding tabs which reduces the potential for damage to the deciduous tooth due to the application of excessive force during the debonding process. The small size of the brackets allow the brackets to fit available crown space on the deciduous teeth. Further the brackets are shaped to minimize mechanical forces applied to the deciduous teeth when engaged with an archwire. The bracket bases are shaped to conform to the morphology of the deciduous tooth crown surface thereby providing an optimal adhesive interface with the deciduous tooth. The deciduous brackets provide proper adhesion to avoid unwanted detachment of the brackets which often occurs when the use of permanent brackets is attempted on the deciduous teeth.

    Abstract: This invention is a dynamic orthodontic bracket system which allows brackets to be adjusted for particular angulations required for each individual tooth of a patient, while the frames are continuously attached to tooth surface. The orthodontist manually adjusts the relationship of a bracket and a frame during treatment eliminating the necessity of a full repositioning of all components. The bracket can be locked or unlocked within the frame with the use of a plate having a tapered thickness. The bracket is positioned such that it can move in various directions to achieve a proper angulation for tooth repositioning. The exterior of the frame can also be textured to provide more secure attachment to the surface of the tooth. This system leads to lower treatment cost, a more stable bracket system, and quicker adjustments of the orthodontic bracket system.

  • Publication number: 20140272751
    Abstract: Orthodontic bracket assemblies with torque-adjusting drums. The drum defines at least a majority of the archwire slot of the corresponding bracket assembly, and the drum may be selectively rotated about its longitudinal axis to adjust the prescriptive force that is applied to a patient's tooth during orthodontic use of the bracket assembly. The bracket assembly includes a positioning assembly that selectively retains the drum in a selected orientation relative to the base of the bracket assembly, thereby defining a prescription to be imparted by the bracket assembly to a patient's tooth. In some embodiments, the bracket assembly includes a biasing mechanism that selectively urges the positioning assembly to a position in which the drum is, or is not, retained in a selected position. In some embodiments, the bracket includes a release mechanism that selectively disengages the positioning assembly to permit adjustment of the drum.

  • Patent number: 8834156
    Abstract: The orthodontic bracket system includes a bracket having a base for attachment to a tooth surface, a stem above the base, tie wings extending from the stem for securing ligatures, and an archwire slot for receiving an archwire defined by the stem and tie wings. Distal and mesial side surfaces of the bracket base are perpendicular to the archwire slot to allow a rotational device to apply rotational force to a tooth perpendicular to the archwire with direct vector-line guidance. Occlusal and gingival edges of the bracket base between the tie wings are scooped-out or recessed to provide more space to receive a tool under an elastic ligature, and select corners of the tie wings are beveled enlarging space to facilitate entry of instruments for removing wire ligatures, to facilitate instrument access for removal and replacement of ligatures, while streamlining tooth rotation to make arch correction more efficient.

  • Publication number: 20140255865
    Abstract: An orthodontic appliance consisting of a two-component bracket assembly and a customized wire where the tooth component of the bracket assembly is semi-permanently glued to the tooth surface and the wire component of the bracket assembly is securely attached to the customized wire. The customized wire has a configuration that is derived from characteristics of both the mal-aligned and aligned states of the teeth. The series of wire components of the bracket assembly are separated by an inter-bracket distance and are specifically oriented along the customized wire to form the customized wire-bracket device. When the wire component and the tooth component of the bracket assembly are engaged, the alignment of the teeth occurs due to the elastic recoil of the customized wire. The customized wire-bracket device is completely detachable and re-attachable to the tooth component of the bracket assembly as are the two components of the bracket assembly.

  • Patent number: 8694142
    Abstract: This invention has provided a direct manufacturing methodology of customized lingual orthodontic brackets by selective laser melting. The procedure is as follows. First of all, measure the dentition data and construct the 3D CAD model of the teeth through reverse engineering. Then a single soleplate of the lingual bracket contacting the tooth surface, as well as the ideal slot position is designed based on the teeth features. The designed models are later imported into the SLM machine and used to produce the brackets with desired materials directly. This method can actualize customized manufacture with highly accuracy, producing highly matched brackets all at once. The invention not only saves time and cost, but also has wide adaptation range and is able to adopt various raw materials. Different raw materials can be utilized in one step to accommodate specific capacity requirement of different parts of the brackets.

  • Publication number: 20140065568
    Abstract: This invention is a dynamic orthodontic bracket system which allows brackets to be adjusted for particular angulations required for each individual tooth of a patient, while the frames are continuously attached to tooth surface. The orthodontist manually adjusts the relationship of a bracket and a frame during treatment eliminating the necessity of a full repositioning of all components. The bracket is positioned such that it can move in various directions to achieve a proper angulation for tooth repositioning. The base of the bracket and the interior surface of the frame can be textured to provide friction and secure the components once positioned for proper tooth movement. The exterior of the frame can also be 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.
