CAD process with Sirona inLab 3D Software
The inLab 3D software V3.81 or higher is necessary to fabricate IPS e.max CAD-on restorations with the Sirona inLab ®
system. The basic operation and function of this software is described in the respective "inLab 3D Operator's Manual".
In addition to the Manual, the following notes on the construction of IPS e.max CAD-on restorations must be observed.
The description is not conclusive and does not include all required details; it is limited to the steps which are relevant in the
context of the IPS e.max CAD-on technique.

In the New dialog, e.g. for the creation of a bridge
restoration, make the following selection:
Restoration: Bridge
Design technique: Multilayer
The "Multilayer" design technique is the software
tool that is used to create IPS e.max CAD-on
restorations.
After the model or prepared teeth have been
scanned the restorative materials are selected.
With this step, the material thicknesses that apply
to the respective material are activated for the
subsequent design.

Make the following individual settings for the frame-
work in the Parameter dialog box:
– Oclusal contact strength: e.g. -50 µm
–> influences the strength of the contact points
– Spacer: e.g. 0 µm
–> individual setting according to the required fit
on the model
– Lingual open angle: 0° – 45°
–> depends on the clinical case at hand or the
desired restoration geometry
