Direction of application

right
It is essential that the material is applied perfectly, especially in the
edge and marginal areas. It is therefore advisable to aim the cannula
directly at all edge and marginal areas. Spraying directly onto the base
may result in an excessively thick layer, which in turn can result in fitting
inaccuracy.
7.2.4

Marking the cervical step

The cervical and lateral edges are coated from the proximal direction.
If the cervical step is located at the same height as the edge of the
gingiva, the spray may cover the borderline between these two
structures.
This boundary can be marked again by running a fine probe along the
step or laterally pulling a rubber cofferdam.
Before you start spraying, you can loosely insert dental floss and then
carefully remove it again.
NOTE
Avoid applying too much or not enough coating. We recommend
blowing the object clean with compressed air after spraying.
