1. It is pre-flexible and can adapt to the root canal path itself.
2.Special design of screw thread,enabling the file to slow down when approaching the apical foramen,and this avoid preforation.
3.Special processing craft makes the file more flexible ,rendering it enhanced fracture resistance and having unique memory recovery.
1.The newest technology of nanometer coating.
2.Special design makes it less possible for the file to be embedded in the root canal wall.
3.comply with canal morphology and maintain the original form of root canal.
