Pop Screw for Upper Arch
Made of stainless steel and biomedical techno polymer.
Continuous expansion movement: the high pressure injection of the polymer
allows a perfect copy of the male thread of the screw ensuring a continuous
smooth expansion without the risk of any undesired turning back in the mouth.
The self-centering rectangular guides ensure a biomechanical and absolutely
controlled symmetrical expansion.
The flexibility of the screw allows the adjustments of any dental regress due
to incorrect use by the patient; they are also very effective as a holding device following a rapid expansion treatment.
Clear Opening Direction
The embossed direction arrows on the plastic body indicate the direction of
opening. When using an acrylic resin with a similar color to the polymer
body, a white arrow provided with the plastic placement tab can be used to
ensure the direction of activation is visible.
