Claim 6

The orthodontic bracket of claim 3 further comprising a third slot formed in said occlusal side of said body member extending transverse said body member intermediate said base surface and said pin slot, said second and third slots being sized and shaped to receive an O-shaped retaining member to thereby capture an archwire in said second slot when a pin is not inserted in said pin slot and said retaining member is engaged in said second and third slots.

Claim 7

In a combination orthodontic apparatus for simultaneous use in the application of lightwire and edgewise corrective techniques and including a solid metal bracket body member, archwire, lightwire archwire, and a locking pin to fasten said archwire and/or said lightwire archwire to said bracket in the application of said edgewise technique and/or said lightwire technique, the improvement comprising said bracket body member having: a base surface for attachment to a tooth, a labial surface, an occlusal side surface and a gingival side surface; a first slot for receiving an archwire, said first slot being formed in said body member extending transverse said bracket body member intermediate said occlusal side surface and said gingival side surface opening at said labial surface and extending from said labial surface toward said base surface to a first distance from said base surface, said first slot being sized and shaped to receive an archwire in the portion of said first slot adjacent said base surface so that said archwire is positioned said first distance from said base surface, said first slot being sized and shaped for use in the edgewise corrective technique; a second slot for receiving an archwire, said second slot being formed in said gingival side surface of said body member extending transverse said body member intermediate said labial surface and said base surface, said second slot being located said first distance from said base surface so that said lightwire archwire is positioned said first distance from said base surface, said second slot being sized and shaped for use in the lightwire corrective technique, said second slot including sloped shoulders to permit tipping of said bracket when a lightwire archwire is received in said second slot; a pin slot extending from said gingival side surface to said occlusal side surface of said body member transverse said first and second slots, said pin slot being located intermediate said labial surface and said base surface at a second distance from said base surface greater than said first distance and such that when said pin is inserted in said pin slot, said pin captures said archwire in said first slot and said lightwire archwire in said second slot thereby positioning both said archwire and said lightwire archwire in said body member said first distance from said base surface of said body member; and a third slot formed in said occlusal side surface of said body member extending transverse said body member intermediate said base surface and said pin slot, said second and third slots being sized and shaped to receive a retaining member to thereby capture a lightwire archwire in said second slot when a pin is not inserted in said pin slot and said retaining member is engaged in said second and third slots.

Claim 8

In a combination orthodontic apparatus for simultaneous use in the application of lightwire and edgewise corrective techniques and including a solid metal bracket body member, archwire, lightwire archwire, and a locking pin to fasten said archwire and/or said lightwire archwire to said bracket in the application of said edgewise technique and/or said lightwire technique, the improvement comprising said bracket body member having: a base surface for attachment to a tooth, a labial surface, an occlusal side surface and a gingival side surface; a first slot for receiving an archwire, said first slot being formed in said body member extending transverse said bracket body member intermediate said occlusal side surface and said gingival side surface opening at said labial surface and extending from said labial surface toward said base surface to a first distance from said base surface, said first slot being sized and shaped to receive an archwire in the portion of said first slot adjacent said base surface so that said archwire is positioned said first distance from said base surface, said first slot being sized and shaped for use in the edgewise corrective technique; a second slot for receiving an archwire, said second slot being formed in said gingival side surface of said body member extending transverse said body member intermediate said labial surface and said base surface, said second slot being located said first distance from said base surface so that said lightwire archwire is positioned said first distance from said base surface, said second slot being sized and shaped for use in the lightwire corrective technique, said second slot including sloped shoulders to permit tipping of said bracket when a lightwire archwire is received in said second slot; a pin slot extending from said gingival side surface to said occlusal side surface of said body member transverse said first and second slots, said pin slot being located intermediate said labial surface and said base surface at a second distance from said base surface greater than said first distance and such that when said pin is inserted in said pin slot, said pin captures said archwire in said first slot and said lightwire archwire in said second slot thereby positioning both said archwire and said lightwire archwire in said body member said first distance from said base surface of said body member; and a third slot formed in said occlusal side surface of said body member extending transverse said body member intermediate said base surface and said pin slot, said second and third slots being sized and shaped to receive a retaining member to thereby capture a lightwire archwire in said second slot when a pin is not inserted in said pin slot and said retaining member is engaged in said second and third slots.
