Abstract: An orthodontic device and, in particular, an orthodontic bracket that is slidable along a wire without external forces is provided. The device may include a first and second gear, each of which are independently movable between a locked position in which the gear is prevented from rotation, and a released configuration in which the gear extends into the channel to engage a wire received within the channel and is rotatable to move the device along the wire. The first gear may be rotatable to move the device in a first direction while the second gear may be rotatable to move the device in a second direction opposite the first direction. Thus, the first and second gears have the ability to move along the wire in short or long distances, as desired.

Abstract: An orthodontic bracket may include a housing portion having a first channel extending from a first end to a second end through the housing portion. The first channel is configured to slidably receive an archwire therethrough. The bracket also include a body portion configured to be received within the housing portion. The housing portion is configured to rotatably mount to the body portion about a first axis and a second axis. The first axis may be in an apico-coronal direction of the tooth. The second axis may be in a buccopalatal direction of the tooth. The bracket further includes a base portion configured to attach to a surface of the tooth. The body portion is configured to slidably mount on the base portion along the apico-coronal direction of the tooth.

Abstract: The present invention relates to a device. The device includes an elongate handle having a proximal end and a distal end; a head portion extending from the proximal end of the elongate handle, the head portion having a first interior-facing surface and an opposing second exterior-facing surface; and a plurality of microneedles extending from, and perpendicular to, the first interior-facing surface of the head portion. Each of the plurality of microneedles has a base connected to the first interior-facing surface of the head portion and a free tip end. The present invention also relates to a method for stimulation of cortical bone formation using the device of the present invention.
