An orthodontic appliance, includes comprising a main body portion, and a traction component, a transmission component and a position occupation component which are independently provided. The traction component is detachably connected to the main body portion and/or the transmission component, so as to achieve switching between a working state and a non-working state; the transmission component and the position occupation component are provided on the main body portion, the transmission component is transmittingly connected to the position occupation component, and the main body portion is provided with a groove; when an effective space of the groove needs to be changed, the traction component is transmittingly connected to the transmission component, so as to drive the position occupation component to at least partially enter or exit the or move in the groove along the width direction of the groove, so as to change the effective space of the groove.

An orthodontic bracket has a base configured for attachment to a tooth surface, a bracket element with an arch wire slot attached to one side of the base, and a clip for securing the arch wire in the slot. The bracket element has a wall portion extending upward along one side of the arch wire slot. This wall portion has three indentations in a line parallel to the mesiodistal direction. There is a channel running entirely through the bracket element underneath the arch wire slot. The clip is substantially U-shaped and has three parallel protrusions shaped to fit within the three indentations of the wall portion, and a locking element. The clip is securable to the bracket by placing the clip through the channel and engaging the locking element onto the bracket element, and placing the protrusions into the indentations of the bracket element.

A self-ligating bracket system comprising a body, an archwire slot receivable for an archwire, and a locking mechanism, the locking mechanism configured to allow a ligating sliding member to move between an open position, such that an archwire may be inserted into and/or removed from the archwire slot, and a closed position, such that an archwire is retained within the archwire slot.

The present invention employs a self-ligating orthodontic bracket comprising a body having a pair of laterally spaced gingival tie wings and a pair of laterally spaced occlusal tie wings, the gingival and occlusal tie wings projecting from a labial surface of the body; an arch wire slot extending mesially-distally across the body and between the gingival and occlusal tie wings to accommodate an arch wire; a free-sliding, controlled-locking, or pivoting clip wherein the clip allows placement and removal of the arch wire when in the open position and prevents the displacement of the arch wire from the bracket member when in the closed position.

Disclosed herein is a slide-type self-ligating orthodontic bracket assembly including: a bracket body block (10) including a base portion (11) configured to be attached to the surface of a tooth, and a body portion (12) formed on the base portion 11 and provided with a wire slot (120), into which the arch wire (W) is inserted, between a first wall (130) and a second wall (140); a cover block (20) configured to slide between an open position for opening the wire slot (120) and a closed position for closing the wire slot (120); and a restraining unit configured to restrain the cover block (20) in the closed position and the open position; wherein a guide protrusion (132), both sides of which are flat surfaces parallel to each other, is formed on the flat top surface of the first wall (130).

This disclosure generally describes an extended buccal tube which is used in connection with braces for the teeth. The extended buccal tube accommodates an arch wire of a sufficient length to allow space to be created between one or more teeth while retaining the arch wire within a tube of the extended buccal tube. As space is created and the arch wire slides through the extended buccal tube, an overall length of the arch wire may be monitored through one or more windows in the extended buccal tube. Tooth pads on extended buccal tube may be rotatable by up to 20 in two axes for fitment purposes. When space has been created between the one or more teeth, extended buccal tube may be cut along scoring lines to separate teeth that were bonded together by the extended buccal tube.
