The materials used by orthodontists have changed rapidly in recent years and will continue to do so in the future. As esthetic composite archwires are introduced, metallic archwires will likely be replaced for most orthodontic applications in the same way that metals have been replaced by composites in the aerospace industry. Archwires are reviewed in the order of their development, with emphasis on specific properties and characteristics, such as strength, stiffness, range, formability, and weldability. Because an ideal material has not yet been found, archwires should be selected within the context of their intended use during treatment.
近年来，正畸医生使用的材料变化迅速，未来也将继续如此。随着美观的复合弓丝问世，金属弓丝在大多数正畸应用中可能会被取代，就像航空航天工业中金属被复合材料取代一样。本文按照弓丝的发展顺序进行综述，重点介绍其特定性能和特征，如强度、刚度、范围、可成型性和可焊性。由于尚未找到理想的材料，因此应根据治疗期间的预期用途来选择弓丝。
