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.

Disclosed is an orthodontic anchor unit to be fixed to a tooth, the unit including a mounting portion, the mounting portion having a length in the mesial-distal direction, a height in the occlusal-gingival direction, a thickness in the buccal-lingual direction and a rear surface fixable to the tooth; a projection extending transversely from the mounting portion in the buccal direction, the projection and the mounting portion defining a longitudinal cavity extending in the mesial-distal direction along a cavity axis, wherein the cavity is provided with an opening and configured to receive and locate an elongate splinting member that extends longitudinally into the cavity through the opening.

An orthodontic self-ligating bracket for orthodontic treatment of maloccluded teeth is provided that includes a bracket body and a bracket door including a coplanar spring. The bracket body has a base that is contoured to attach to a surface of a tooth, a archwire slot on the top side of the bracket body extending in a mesiodistal direction and configured to releasably retain an archwire, and a bracket groove on the top side of the bracket body extending in an occlusogingival direction towards the archwire slot. The coplanar spring includes a spring body and one or more legs that deflect in direction generally coplanar with a plane of motion of the bracket door. The one or more legs interact with one or more depressions in the bracket body to move and retain the bracket door on the bracket body.

An orthodontic appliance and associated systems and methods are disclosed herein. In some embodiments, the appliance comprises an anchor configured to be positioned adjacent a patient's teeth, and an arm extending away from and coupled to the anchor. The arm can include a first end portion at the anchor and a second end portion configured to be coupled to a securing member adhered to a tooth of the patient. The second end portion can include a first region and a second region extending from the first region at an angle. When the appliance is positioned adjacent the patient's teeth and secured to the securing member, the first and second regions may inhibit the second end portion from translating and/or rotating relative to the securing member.

An orthodontic bracket and archform system that uses friction-free mechanics are disclosed. The archform can have a male fastener that can be retained within an orthodontic bracket. The orthodontic bracket can have varying locking mechanism, such as deflectable tabs, springs, locking pins, and others, that can cooperate with features of the male fastener to prevent sliding between the archform and the bracket.

A bracket attachment system is described herein. One variation of an orthodontic bracket assembly generally comprises a main body having a contact surface for placement against a surface and defining a wire slot therethrough. A covering having a retention member configured to be inserted at least partially into the wire slot when the covering is positioned upon the main body may be included such that when a wire is positioned within the wire slot, the wire may be retained via the retention member in a secured position.

An orthodontic appliance may include an archwire and multiple orthodontic brackets. The archwire may fit within a human mouth and contain multiple male connectors. Each orthodontic bracket may have a configuration that facilitates attaching the orthodontic bracket to a single tooth. Each orthodontic bracket may allow one of the male connectors to be locked into the orthodontic bracket with a snapping action. The male connector may be unable to slide with respect to the orthodontic bracket after being locked in the orthodontic bracket. A manual unlocking action may allow the male connector to disengage from the orthodontic bracket.
