Abstract

The purpose of this article is to introduce Optiflex(TM), the first non-metal archwire in orthodontics. This clear archwire is comprised of three layers: a silicone dioxide core, a silicon resin middle layer and a stain-resistant nylon outer layer. It is available in two sizes: 0.017" and 0.021". Optiflex was compared to three other flexible archwires (Niti, Respond and Nitinol) by means of tensile, bending and time-dependent effects tests. The results showed that : 1. The tensile strength of Optiflex was significantly lower than that of metal archwires. 2. The force delivered by Optiflex was much lighter and more constant than those delivered by other archwires. 3. The force of Optiflex was less than half the force delivered by at "Respond" archwire of similar size. 4. Time-dependent effects of Optiflex were almost identical to those of nickel-titanium. These mechanical advantages, along with its esthetic properties and stain resistance, make Optiflex a unique addition to orthodontic archwires currently available. The new archwire is highly effective in the alignment of crowding in most orthodontic cases, particularly adults with special esthetic considerations.

光纤作为正畸弓线:Optiflex
本文的目的是介绍Optiflex(TM),第一种非金属弓丝在正畸。这种透明的拱形钢丝由三层组成:二氧化硅芯,硅树脂中间层和耐污尼龙外层。有0.017"和0.021"两种尺寸可供选择。通过拉伸、弯曲和时间相关效应测试,将Optiflex与其他三种柔性弓丝(Niti、response和Nitinol)进行了比较。结果表明:1。Optiflex的抗拉强度明显低于金属弓丝。2. Optiflex传递的力比其他拱线传递的力更轻,更稳定。3.Optiflex的力小于同等尺寸的“响应”弧线所产生的力的一半。4. Optiflex的时间依赖性效应与镍钛几乎相同。这些机械优势,以及其美观性能和抗污性,使Optiflex成为目前可用的正畸弓线的独特补充。在大多数正畸病例中,特别是有特殊审美考虑的成年人,新的弓丝在拥挤的对齐中非常有效。
