Physical properties
Vectris frameworks are characterized by an intima-
te stress-free fit and beneficial physical properties
thanks to a special manufacturing process that
combines the use of vacuum, pressure and light.
The frameworks are automatically formed and
polymerized in the VS1 framework former.
Furthermore, a newly developed working
technique – based on the Transil matrix material –
facilitates the fabrication of cusp-supporting fra-
meworks. The flexural strength of these frame-
works is superior to that of previous FRC frame-
works.
Aesthetic properties
The translucent, tooth-coloured fibre wafers per-
mit the fabrication of highly aesthetic frameworks.
Light can pass through the restoration without
being blocked by opaque areas of the substruc-
ture. The advantage of the FRC framework is also
apparent at the transition from the pink tissue
colour to the white tooth colour. The grey mar-
gins typically associated with metal restorations
are not present in Vectris-based reconstructions.
The cervical area exhibits a lifelike aesthetic
appearance.
