Self-ligating low profile orthodontic bracket

A self-ligating orthodontic bracket comprising a base plate having a rear surface and a front surface, adhesive means mounted on said rear surface of said base plate to attach the bracket to the surface of a tooth, and said base plate having its front surface provided with a transverse slot for receiving an arch wire in partially engaged position displaced up from the bottom of the slot, and a cover plate extending across the front surface of said base plate to cover said base plate and said slot, said cover plate having a lower edge connected to said base plate to cause said cover plate to be resiliently self-biased against the front surface of said base plate for continually and progressively forcing the arch wire down into the transverse slot while the bracket is in place, the cover plate being separated into two sections, a first lateral protuberance mounted on one of the sections of the cover plate, and a second lateral protuberance mounted on the base plate, said first and second protuberances being used for elastic attachment to enhance cover plate pressure toward the base plate.
