An archwire is received in the secondary bracket. The primary bracket is attached to the tooth and the secondary bracket engages the primary bracket, thereby holding the secondary bracket and the archwire in place. Various configurations of the secondary bracket can be used with the primary bracket for producing desired tooth movements. A novel pin and ligature assembly can be used with the bracket assembly or a conventional bracket.

Abstract: In order to provide an orthodontic bracket having no tie wings, capable of removing drawbacks of prior art brackets, in an orthodontic bracket according to the present invention a main body of the bracket is made of shape memory alloy or resin. Further, in lieu of tie wings, there are disposed nail portions for holding an arch wire in a slot of the bracket. Owing to such a construction, the orthodontic force can act thereon with a high efficiency and the size of the bracket can be reduced. In addition, since the tie wings are unnecessary, accidents due to a cut end of a ligature wire are reduced.

Abstract: A dental orthodontic bracket is made from a body of a ceramic, a polymer or a composite thereof, the body having a longitudinal slot for an archwire formed by opposed upstanding wall portions on a base. The wall portions each have a pair of lateral wings at opposite end portions of the slot and an intermediate portion joining the wings. The wings have convex outer surfaces smoothly joined with a concave outer surface of the intermediate portion thereby forming a sinusoidal outline. The bottom surfaces of the wings form a clearance space with the base for a ligature wire clamp. The bottom of the slot is located above the bottom surfaces of the wings and the lowest point of the wings is at their tips. The upper surface of the wings is convex and the bottom surface concave.

Abstract: A new orthodontic bracket has a mesial-distal extending labially-open arch wire slot that in gingival-occlusal cross section is curved at its lingual face about a mesial distal axis and has its gingival and occlusial faces which usually are straight smoothly joining the lingual face and extending away from one another to form a slot opening of greater gingival-occlusial dimension. A spring retainer member embraces the gingival, occlusial and labial faces and is movable between a slot open position and a slot closed position, in the latter of which it opposes any protrusion of an arch wire out of the slot caused by misalignment between the slot and the arch wire The retainer is held in the slot closed position by latches which permit a small movement of the retainer away from the fully slot closed position, but which oppose such movement by spring and cam action.

Abstract: An orthodontic bracket has been designed which can be made of ceramic material. The bracket can be used for correcting Class II and Class III malocclusions without the use of a Kobiashi tie, ball hook, or power hook, which had previously been used to make such corrections. This invention, on the other hand, employs an integral hook design, which makes use of the same mechanics, but without requiring any brazing or welding of the hook to the body of the bracket.

Abstract: An edgewise bracket (10) is provided with notches (34, 36, 38 and 40) in wing tips (24, 25, 26 and 27), respectively. The notches (24, 25, 26 and 27) are generally concave and have a mesiodistal width slightly greater or slightly less than the thickness of an archwire retaining device (32) depending on whether the device (32) is a metallic wire or an elastomeric ligature. The archwire retaining device (32) is inserted into the notches (34, 36, 38, and 40) to retain an archwire (30) within a slot (28) which has a depth greater than a thickness of the archwire (30). The device (32) has selectively reduced undesired frictional contact with the archwire (30), and, therefore, frictional interference between the device (32) and the archwire (30), and the archwire (30) and the bracket (10) is reduced or eliminated.

Abstract: An orthodontic appliance has a bracket portion with an archwire slot formed therein. The archwire slot extends in the mesial-distal direction of the appliance and is dimensioned to receive an archwire. The orthodontic appliance has at least one pair of tie-wings. Each tie-wing projects outwardly from the bracket portion on an opposite side of the archwire slot with respect to the other tie-wing. One pair of opposing shoulders are located on the mesial end of the bracket portion, and another pair of opposing shoulders are located on the distal end of the bracket portion. Each shoulder is located on an opposite side of the archwire slot relative to the other shoulder of the pair. Each shoulder is adapted to support a ligature thereon, and is dimensioned and located with respect to the archwire slot, so that the ligature is spaced above an archwire received therein. The orthodontic appliance is therefore permitted to move relative to the archwire during orthodontic treatment.

Abstract: An orthodontic bracket with a self-contained seating and locking mechanism which incorporates a slidable, tapered and rotatable plug with an attached lever system. When the plug is rotated, the lever system comes in contact with and seats an archwire contained in the bracket slot. When the plug is then moved laterally, a condition of frictional retention is achieved. The archwire is thus firmly seated and locked in its slot by the lever system. When the plug is next moved in the opposite direction, the archwire is once again freed.

Abstract: An orthodontic bracket having a transverse slot for receiving a conventional orthodontic arch wire, and which is constructed so that a resilient tie ligature used to retain the arch wire in place in the slot is supported on the bracket in a doubled-over configuration. This permits the arch wire to be more firmly and positively held in the transverse slot of the bracket, and it permits a reduction in size of the bracket because it eliminates the need for the gingival portion of the peripheral groove around the bracket which is used in the prior art brackets to retain the ligature.
