Bracket for permitting tipping and limiting uprighting

An orthodontic bracket mountable on the crown of a tooth, said bracket having a body with a horizontally opening archwire slot and a single tie wing having gingival and occlusal tips, the improvement being in the archwire slot for crown tipping and limiting root uprighting, said archwire slot defined by diagonally opposed archwire engagement faces so that, where the archwire extends substantially parallel to the occlusal plane, mesiodistal crown tipping forces applied to the tooth will tip the crown relative to the archwire and root uprighting forces applied to the tooth will upright the root until the wire is engaged by at least some of the diagonally opposed wire engagement faces which are at predetermined locations to ultimately position the long axis of the crown at a desired vertical inclination, said slot including fulcrum means, said engagement faces which position the long axis of the crown at a desired vertical inclination extend parallel to the occlusal plane and said other engagement faces extend at an angle to said occlusal plane, whereby said bracket is mesiodistally pivotal about a generally horizontal axis and said slot and archwire being sized so that the archwire substantially fills the area between the fulcrum means and the engagement faces limiting vertical inclination when the tooth is uprighted.

An orthodontic bracket mountable on the crown of a tooth and coacting with an archwire extending substantially parallel to the occlusal plane, said bracket having a body with a horizontally opening archwire slot and at least one tie wing, said tie wing having gingival and occlusal tips, said archwire slot having at least one crown tipping stop and at least one root uprighting stop, each of said stops being at a different angle to the vertical axis of said bracket, said crown tipping stop being at an angle to the occlusal plane and said root uprighting stop being parallel to the occlusal plane when the tooth is uprighted, whereby said bracket is mesiodistally pivotal about a generally horizontal axis.

An orthodontic bracket mountable on the crown of a tooth and coacting with an archwire extending substantially parallel to the occlusal plane, said bracket including a body having a single tie wing with a horizontally opening archwire slot, said tie wing having gingival and occlusal tips, said tips having parallel gingival and occlusal edges disposed to be parallel to the occlusal plane when the tooth has been moved to the desired position, and said archwire slot including a crown tipping surface and a root uprighting surface to respectively limit tipping and uprighting movements, each of said surfaces being at a different angle to the vertical axis of the bracket, said crown tipping surface being at an angle to the occlusal plane and said root uprighting surface being parallel to the occlusal surface when the tooth is uprighted, whereby said bracket is mesiodistally pivotal on the archwire about a generally horizontal axis.

An orthodontic bracket mountable on the crown of a tooth, said bracket having a body with a horizontally opening archwire slot, the improvement being in the archwire slot for crown tipping and limiting root uprighting, said archwire slot defined by diagonally opposed archwire engagement faces, some of which allow tipping and some of which limit uprighting, said faces being arranged so that, where the archwire extends substantially parallel to the occlusal plane, mesiodistal crown tipping forces applied to the tooth will tip the crown relative to the archwire and root uprighting forces applied to the tooth will upright the root until the wire is engaged by diagonally opposed wire engagement faces which are at predetermined locations to ultimately position the long axis of the crown at a desired vertical inclination, said slot further including fulcrum means, said diagonally opposed faces which allow tipping extend at an angle to said occlusal plane and said diagonally opposed surfaces which limit uprighting extend parallel to the occlusal plane when the tooth is uprighted, whereby said bracket is mesiodistally pivotal about a generally horizontal axis, and said slot and archwire being sized so that the archwire substantially fills the area between the fulcrum means and the engagement faces controlling vertical inclination when the tooth is uprighted.
