Intra-oral imaging
To prepare 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.
IPS ® Contrast Spray Chairside is used to achieve
optimum recordings for CAD/CAM restorations. The
IPS Contrast Spray Chairside balances out the different
optical properties of the natural tooth (dentin and
enamel) and thus permits optimum impressions using a camera. With
the atomizing nozzle, an optimum covering layer with a detailed
representation of the preparation surfaces and margins is achieved
easily and efficiently with only a short spray
discharge. Angled atomizing heads are
available for the spray. Please observe the
corresponding Instructions for Use.
Milling
To mill the restoration, the IPS Empress CAD Block is selected in accordance with the
corresponding clinical situation. The clinical situation not only determines the
selection of the block in the required shade and translucency, but also the size of
the block used. Once the desired block has been selected, it is mounted in the
CAM unit and the restoration is milled.
Several options are available to finish and complete the restorations. Please refer
to the Chapter "Practical Procedure - Fabrication of IPS Empress CAD
Restorations" for detailed descriptions of the individual working steps of the
various processing methods.
