*) VITA YZ XT is limited to maximum of three units.
**) In Canada VITA YZ ST is limited to bridges with six units.

Please note:

When designing the framework, pay attention to anatomically reduced tooth shapes. 
The cusp should be supported according to the anatomical progression. When preparing 
a ceramic veneer, a uniform layer thickness across the entire surface to be veneered 
must be ensured. The entire thickness of the ceramic layer, however, should not exceed 
2 mm (the optimal layer thickness ranges from 0.7 to 1.2 mm).
When designing fully anatomical restorations, the minimum wall thicknesses for the 
respective material must be observed. The aim is to obtain a uniform material thickness.
Clinical success cannot be reliably assured in the event that compliance with the given 
design guidelines and minimum wall thickness is not met.

4.  

CAD process

For seven units or more, a sinter support for the milled restoration should be designed 
for bridge frameworks from VITA YZ T / HT / ST. If no sinter support is attached to these 
bridge structures, it is possible for distortion to occur as a result of the sintering process, 
which may in turn lead to an imprecise fit in the finished restoration.
The instructions on the design of the sintering support from the individual software 
manufacturers are to be observed.
However, if this sinter support consists only of a leftover piece of the disc (sintering 
tongue), the volume should be reduced to ensure even heating during the sintering 
process.

5.  

Enlargement factor

All VITA YZ materials are porous before sintering. Sintering acts as a kind of "compression 
process," which results in the materials shrinking by approximately 20%. As a result, all 
restorations must be milled according to the specified enlargement factor to compensate 
for the shrinkage of the material during the sintering process. The corresponding blank 
imprint must be entered into the respective CAM software (as plain text on the disc or 
as a barcode on the block). Some software requires the factor (e.g., enlargement factor 
1.2345) for the discs or the corresponding X, Y values (e.g., VGF: X, Y = 23.45) and for 
some providers, also the Z values   (e.g., Z = 23.01). For blocks, the corresponding barcode 
is scanned into the CAM software.

6.   Milling the restorations

VITA YZ processing must be performed with a validated CAD/CAM system. For information 
on the processing parameters, see 
"Processing information for VITA YZ CNC machines." Further information is available on 
the internet at: https://www.vita-zahnfabrik.com/systempartner
•   VITA SYSTEM SOLUTIONS with specific holder systems for: inLab System (Sirona 

Dental Systems GmbH); CEREC System (Sirona Dental Systems GmbH)

•  VITA UNIVERSAL SOLUTIONS in universal disc geometries (

98.4 mm) for the 

following CAD/CAM systems: CORiTEC series (imes-icore GmbH); ULTRASONIC series 
(DMG Mori AG); RXD line (Röders GmbH); inLab MC X5 (Sirona Dental Systems GmbH);

Please note: restorations from VITA YZ ST and VITA YZ XT are not to be milled wet. 
They must be milled dry.
