Abstract
Abstract An orthodontic bracket is disclosed which is formed from an elongated section of metal that enables it to be directly bonded to the buccal surfaces of a plurality of the teeth. The bracket is attached to the buccal surfaces of the teeth by direct bonding to a plurality of contoured surfaces which have been formed from the elongated section of metal. A bent section is formed between each adjacent pair of contoured surfaces whose length is an approximate function of the distance between the centers of the teeth to which the adjacent contoured surfaces are attached. An archwire attachment is formed in each of the bent sections. Buccal and head gear tubes are attached to one of the bent sections.
