摘要:
Orthodontic bracket assemblies with archwire cradles that pivot in correspondence with the rotation of pivot-adjusting drums. The orthodontic bracket assemblies include a pivot-adjusting drum that is configured to be selectively rotated relative to a bracket base about an adjustment axis within a range of operative rotation positions, an archwire cradle that is configured to be selectively pivoted about a cradle axis relative to the bracket base within a range of operative pivot positions, and an adjustment driver that is operatively coupled to the archwire cradle and the pivot-adjusting drum and causes the archwire cradle to pivot relative to the bracket base in correspondence with a rotation of the pivot-adjusting drum. A rotation of the pivot-adjusting drum about the adjustment axis adjusts the torque that is applied to the patient's tooth during prescriptive use of the bracket assembly.

Adjustable-prescription orthodontic bracket assemblies. The orthodontic bracket assemblies include a bracket body, an arcuate core, and a retention structure. The bracket body defines an arcuate receptacle that extends toward a base of the bracket body from a top of the bracket body. The arcuate core is received within the arcuate receptacle and defines an archwire slot. The arcuate receptacle is shaped to retain the arcuate core therein and to permit rotation of the arcuate core therein. The retention structure is configured to selectively retain the arcuate core at a selected rotational orientation with the bracket body. The retention structure is configured to selectively transition between a disengaged configuration, in which the retention structure permits rotation of the arcuate core relative to the bracket body, and an engaged configuration, in which the retention structure retains the arcuate core at the selected rotational orientation.

Mechanically bistable thermal devices and methods of utilizing the same. The mechanically bistable thermal devices include a mechanically bistable element and a thermal element. The mechanically bistable element is configured to be selectively transitioned between a straight conformation, in which the mechanically bistable element defines an elongate shape, and a wrapped conformation, in which the mechanically bistable element defines an arcuate shape and is configured to at least partially encircle an encircled form. The thermal element is configured to exchange thermal energy with the encircled form when in thermal contact with the encircled form and includes a thermal material that includes a fluid and/or a granular solid. The methods include activating the thermal element and transitioning the mechanically bistable element from the straight conformation to the wrapped conformation to at least partially encircle the encircled form with the mechanically bistable device.

Prescription-altering accessories for use with orthodontic brackets to modify the corrective forces applied to the teeth by orthodontic bracket assemblies that include the orthodontic bracket. The orthodontic bracket assemblies may include specialized orthodontic brackets that are designed and/or configured for use with the prescription-altering accessories. Additionally or alternatively, the orthodontic bracket assemblies may be configured for use with traditional orthodontic brackets, such as by being operatively attached thereto. The prescription-altering accessories may be configured to generate a modifying force to alter any suitable tip, torque, rotation, and/or step corrective force that may be applied to one or more teeth within a dental arch to improve, or otherwise modify, the occlusion of the one or more teeth. The prescription-altering accessories may be configured to alter the corrective force without removal and/or modification of an installed archwire and/or without removal and/or replacement of installed orthodontic brackets.

Electromechanical systems, methods, orthodontic brackets, and tools for adjusting orthodontic prescriptions of orthodontic brackets with adjustable archwire passages are disclosed herein. The methods include operatively engaging an orthodontic bracket with an engagement structure of an electronic orthodontic adjustment tool, determining a present orientation of an archwire slot of the orthodontic bracket, displaying a displayed orientation of the archwire slot, and adjusting the orientation of the archwire slot based on the displayed orientation. The orthodontic brackets include a base, a body, a retention structure, a transmitter, and may include an orientation-determining structure. The tools include an engagement structure, an orientation indicator, and may include an orientation-determining structure.

Adjustable-prescription orthodontic brackets that include a bracket body, a repositionable core that defines an archwire slot, and a core positioning assembly. The bracket body defines a core receptacle into which the core is received and selectively moved within a plurality of prescriptive orientations. The core positioning assembly is selectively transitioned between a disengaged configuration, in which the core positioning assembly permits movement of the core relative to the bracket body within the plurality of prescriptive orientations, and an engaged configuration, in which the core positioning assembly retains the core at the selected prescriptive orientation. The core positioning assembly includes a core clamp with a core engagement surface configured to be selectively engaged with the core, and an actuator configured to selectively secure the core clamp in engagement with the core to retain the core at the selected prescriptive orientation.

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.
