ABSTRACT:
An archwire is comprised of an elongated wire of nickel/titanium alloy in a generally arcuate configuration and a pair of tubular metallic sleeves in spaced apart relationship at predetermined points along the length of the wire. The sleeves are crimped onto the wire, and an upstanding metallic post is bonded on each of the sleeves. The posts are seated in the crimped area of the archwire and are secured thereto by brazing. The crimp formation is then heat set.
