Piston Spring Screw Kit

For movement of single teeth. These screws exert a constant pressure on the tooth to be moved, and their compact size allows them to be easily built into appliances. Treatment is started with the 4mm screw, which is exchanged for the 6mm and finally the 8mm screw as the tooth is moved.

Kit consists of:
5 each piston spring screws (4mm, 6mm and 8mm)
5 position holding screws
10 serrated housing nuts
1 reamer and 1 screw driver
