摘要：
Orthodontic appliances in accordance with the present invention are formed from amorphous alloys having a supercooling liquid region. The appliances have high corrosion resistance, high durability and high strength. The appliances are particularly useful when changes and adjustments in the orthodontic state become necessary in the course of orthodontic treatment. The present invention also provides improvements in the base surfaces of orthodontic appliances adapted to be bonded to tooth surfaces. The appliances can consequently be securely affixed to tooth surfaces.
