The VSS Patrix has smooth, parallel sides on the attachment section and the remaining bar has a 2
degree taper which simplifies the fitting of an overcasting onto the implant bar frame. The bar pattern
can be reduced along the base as well as the mesial and distal areas to fit the required space. The VSS
has three levels of retention: green (light), yellow (medium), and red (high); however the retentiveness
can be customized on a per patient basis by simply polishing the implant bar frame until a comfortable
grip is achieved.
