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 ensures 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 colour to the polymer body, a white arrow provided with the plastic placement tab can be used to ensure the direction of activation is visible.
