作者介绍了用改良的具有透明性及柔软性的光纤维制作的OPTIFLEX型正畸弓丝.以及应用此丝的临床病例。并将最初制作及最后定丝的此弓丝的审美性及物理学特征进行了研究.对该弓丝的耐着色性与几种常用弓丝进行了弯曲后的试验比较。结果显示,此丝由于具有透明效果,审美性良好,而且具有耐着色性,认为较之其它弓丝具有更多的优 The authors present an OPTIFLEX orthodontic archwire made of an improved optical fiber with transparency and softness, as well as clinical cases using this filament. The aesthetic and physical characteristics of the archwire, which was originally made and finally set, were also studied.The coloring resistance of the archwire was compared with that of several commonly used archwire after bending. The results show that the silk because of the transparent effect, good aesthetic, and has resistance to coloring, that compared with other arch wire has more excellent
