AMENDED CLAIMS received by the International Bureau on 14 January 2018 (14.01.2018) [Claim 1] [Amended] An orthodontic bracket, comprising: a bracket body; at least one embedded bracket slot formed in said bracket body to receive an arch wire therein, said bracket slot having a labially/buccally opening, extending along said bracket body in mesio-distal direction, defined by two parallel sidewalls and one floor; a bracket base connecting to the underside of said bracket body; a first pair of opposing tie wings extending occlusally and gingivally from said bracket body, located on the mesial end of said bracket body, defined as the mesial pair of inner tie wings, and the labial/buccal surface of said mesial pair of inner tie wings allowing support for elastic ties so as to provide passive ligation of the engaged arch wire in said bracket slot; a second pair of opposing tie wings extending occlusally and gingivally from said bracket body, located on the distal end of said bracket body, defined as the distal pair of inner tie wings, and the labial/buccal surface of said distal pair of inner tie wings allowing support for elastic ties so as to provide passive ligation of the engaged arch wire in said bracket slot; a third pair of opposing tie wings extending occlusally and gingivally from said bracket body, located at the central portion of said bracket body which extends further towards the labial/buccal side, raised above said mesial pair of inner tie wings and said distal pair of inner tie wings, defined as outer tie wings, forming the second level of the slot depth of said bracket slot, wherein the mesio-distal width of the outer tie wings is larger than the mesio-distal inter-distance between the mesial pair of inner tie wings and the distal pair of inner tie wings [Claim 2] [Amended] An orthodontic bracket, comprising: a bracket body; at least one embedded bracket slot formed in said bracket body to receive an arch wire therein, said bracket slot having a labially/buccally opening, extending along said bracket body in mesio-distal direction, defined by two parallel sidewalls and one floor; a bracket base connecting to the underside of said bracket body; a first pair of opposing tie wings extending occlusally and gingivally from said bracket body, located on the mesial end of said bracket body, defined as the mesial pair of inner tie wings, and the labial/buccal surface of said mesial pair of inner tie wings allowing support for elastic ties so as to provide passive ligation of the engaged arch wire in said bracket slot; a second pair of opposing tie wings extending occlusally and gingivally from said bracket body, located on the distal end of said bracket body, defined as the distal pair of inner tie wings, and the labial/buccal surface of said distal pair of inner tie wings allowing support for elastic ties so as to provide passive ligation of the engaged arch wire in said bracket slot; a third pair of opposing tie wings extending occlusally and gingivally from said bracket body, located at the central portion of said bracket body which extends further towards the labial/buccal side, raised above said mesial pair of inner tie wings and said distal pair of inner tie wings, defined as outer tie wings, forming the second level of the slot depth of said bracket slot, wherein the mesio-distal width of the outer tie wings is equal to the mesio-distal inter-distance between the mesial pair of inner tie wings and the distal pair of inner tie wings |
