  • Orthodontic bracket with slot base
    Patent number: 8678817
    Abstract: The present invention provides an improved orthodontic bracket. According to one embodiment, the orthodontic bracket includes a mounting base for attachment to a tooth surface and an archwire slot formed upon the base and sized for receiving an orthodontic archwire. The bracket body has a facially curved slot lingual sidewall that causes the archwire to contact the bracket body. The bracket embodiment has a mesial and distal convexity contoured bracket base and slot lingual sidewall such that there is no contact by an archwire when an archwire is placed in an aligned dental arch. Additional features of the improved design are occlusal and gingival convex contouring of the tie wings such that there are no sharp corners on the archwire slot.
