US Classification:

433 9

Abstract:

An improved edgewise orthodontic bracket is disclosed. In one embodiment, a bracket comprises a single pair of opposing T-shaped tie wings which define an archwire slot therebetween. Notches are provided on each of the mesial and distal sides of the center leg of each T-shaped tie wing for selectively receiving a ligating device. The notches are defined in the gingival/occlusal edges of the tie wings and comprise sloped portions that extend labially towards the archwire slot. Convex sidewall portions and convex floor portions are provided in the archwire slot adjacent to the notches. The body of the bracket is interconnected to a base that includes a continuous series of characters that serve as texturing to facilitate bonding of the bracket with a tooth. A discontinuous perimeter rail may be used at the edge of the base. A method for forming a bracket is also provided.

International Classification:

A61C 3/00

US Classification:

433017000

Abstract:

A convertible orthodontic bracket is disclosed, wherein an archwire slot therein has a removable slot covering, thereby allowing the bracket to serve as a buccal tube during a first stage of treatment and an edgewise bracket during a subsequent phase of treatment. The slot covering is removable by detaching the slot covering from the bracket body along one or more predetermined extents of weakness, wherein each such extent of weakness includes perforations or voids providing a passage between an exterior of the bracket and an interior of the first archwire slot.

US Classification:

433 10

Abstract:

A triple wing orthodontic bracket, bracket cover, and method of use is disclosed. The bracket has a slot liner for reducing friction between an archwire and the bracket, wherein the liner is flared at its ends. The bracket cover has: a rod-shaped hinge for rotating in recesses between a bracket base, and bracket wings on one of a gingival and occlusal bracket side, a slot cover, and a cross member for rotating the slot cover between covering a bracket archwire slot, and uncovering the slot, wherein the rotation pivots the hinge in the recesses. The hinge and recesses frictionally engage one another, wherein in a first position, the hinge attaches and detaches from the bracket, and after pivoting the hinge to another position in the recesses, the hinge is secured therein. Interaction between the hinge and the recesses may cause the slot cover to move to cover the slot.
