A 13cm horizontal notch thermal-forming plier for clear aligners.

Horizontal features push across the tooth surface and accent root torque; vertical features act along it and help control rotation.What size is the working point?4.23mm on the inside and 3.98mm on the outside, on a 13cm plier — sized to press a clean, consistent horizontal notch into the aligner material.Can aligner pliers be autoclaved?Yes.
