Intraoral Imaging
To prepare for the optical imaging, OptraGate ® is placed to facilitate access to the
treatment field. OptraGate is a clinical auxiliary device that retracts lips and cheeks
during dental treatment. It enables a full view of the treatment field, facilitates the
accessibility, and improves the moisture control in the oral cavity.
Milling
In order to mill the restoration, the appropriate IPS e.max CAD block is selected in
accordance with the clinical situation. It not only determines the selection of the block
in the required shade, but also the block size to be offered. Once the desired block
has been selected, it is mounted in the CAM unit and the restoration is milled.
IPS ® Contrast Spray Chairside is used to prepare the intraoral situation
for optical imaging. The IPS Contrast Spray Chairside balances out the
different optical properties of the natural tooth (dentin and enamel) and
thus permits optimum recording using the camera. The optimized geo-
metry of the rotatable single-use nozzle provides good accessibility to the
preparation. The IPS Contrast Spray is available in the colours blue and
cream; both versions feature a fresh lemon flavour.
Virtual ® CADbite is a scannable bite registration material
with a reflecting surface, which is ideally suitable for capturing
images with intraoral scanning devices (antagonist
data).
