Self-ligating bracket with cantilever locking beam mechanism and other locking elements for ligating sliding members, and methods of making and use thereof

A self-ligating bracket system comprising:

• a bracket body having:
• an archwire slot extending in a lateral direction, the lateral direction being coextensive with an archwire retained in the slot,
• a sliding channel receivable for a ligating sliding member, and
• a recess;
• and
• a cantilever locking blade receivable in the recess,
• wherein the cantilever locking blade comprises a first planar face and a curved portion, the curved portion curving toward the archwire slot,
• wherein the first planar face has a width extending in the lateral direction and a height in a direction approximately perpendicular to an axial direction, and
• wherein the cantilever locking blade is configured to be deflected in a direction approximately perpendicular to an axial direction of the sliding channel, such that the cantilever locking blade locks the ligating sliding member in a closed or open position.
