A classic for 30 years. New version.
The Snap VDP from FORESTADENT is a maxilla expansion screw for the VDP appliance which has been optimised in design and application. It has significantly reinforced protrusion bars to which an additional rib was added. Deformation or damage to the bars from extra-oral influences can therefore be prevented. To ensure optimum patient comfort, they also have an extremely smooth surface as well as rounded edges.
The Snap VDP is equipped with the proven snap-lock mechanism. It secures the screw from reversing as the flat spring engages noticeably and controllably after activation of the spindle. Per activation (1/4 rotation) a maxilla expansion of 0.2 mm can be achieved, whereby the screw can achieve a maximum expansion of 7 mm. If accidentally over-activated, the screw can be turned back easily.
Often, space is severely limited in the maxilla and mandible. To ensure a trouble-free waxing of the plastic place holder during lab fabrication of the appliance, the palatal side was extended. The correct positioning of the maxilla expansion screw is thus easy to realise.
