POP® EXPANSION SCREWS FOR UPPER ARCH, ASSORTED COLOURS
POP® EXPANSION SCREWS FOR LOWER ARCH, ASSORTED COLOURS
The POP® screw is made of steel and technopolymer. The screw body is available in five colours. POP® screws produce a constant expansion force with no risk of undesired turning back in the mouth. The male screw is not in contact with the orthodontic resin: screw operation is not influenced by the quality of the technical procedure or non-compliant curing times.
