摘要
Twisted Files(TF)是一种新型的镍钛机动的根管预备器械,它采用扭制的方法制成,且有特殊的外形特点,与其他的镍钛器械相比,其具有更好的抵抗弯曲疲劳机械分离和扭曲机械分离的能力和弹性,且使用简单。因此,在根管成形中TF具有安全和高效两个方面的优势,尤其适应于弯曲根管的预备。在此对TF的组成及外形特点、物理机械性能、使用方法等予以综述。
Twisted files（TF）is a new type of nickel-titanium rotary root canal preparation equipment,which is made using the twisting methodcharacterized bya special appearance,featured with better mechanical ability and elasticity resisting bending fatigue and mechanical distortion separation compared with other nickel titanium equipments,and simple usage.With the advantages of safety and efficiency in the root canal shape,TF are especially suitable for bending tube preparation.Here is to make a review on TF composition,appearance characteristics,mechanical properties and using methods.
