Abstract
Abstract A plurality of strands are disposed in a braided relationship to form a multi-strand filament. Each of the strands is formed from a material having substantially fifty five percent (55%) titanium and forty five percent (45%) nickel by weight. The strands have the properties of being formed to any desired configuration in an arched relationship at a temperature below a particular temperature such as 10 DEG C - 15 DEG C. and of returning to the desired configuration when bent from the desired configuration at any temperature above the particular temperature. The multi-strand configuration is then bent from the desired configuration at a temperature above the particular temperature to conform to the actual configuration of the teeth in the patient's mouth and is attached to the patient's teeth in this bent configuration. The multi-strand filament returns to the desired configuration while attached to the patient's teeth, thereby causing the position of the teeth in the patient's mouth to become disposed in the desired configuration. In another embodiment, the multi-strand braid (42) envelopes a centrally disposed wire (40). The centrally disposed wire may be made from the same material as, or a different material than, the braids, depending upon the characteristics desired.
