Reference SL Articulator and Face Bow Systems
Now the bars of the bite fork supports can be
moved upwards, until they touch the bite fork;
then they can be fixed. The position of the bite
fork must not be altered.
The next step is selecting the ideal distance
block. First, the upper jaw model must be set
into the corresponding impressions on the bite
fork; then close the upper section of the articu-
lator that it rests in solid contact on the anterior
face-bow pins. Analyze the distance between
the upper section and the model. The distance
block which best fills the spatial requirements
can now be chosen. Make sure that there is a
thin, but even layer of plaster on the selected
block. This will minimize the distortion effects of
plaster expansion.
The articulator can now be opened and the dis-
tance block, with mounting plate already at-
tached, can be fitted in. Moisten the model, and
make sure to apply sufficient mounting plaster
on both the mounting plate and the model.
Close the articulator and allow the plaster to
harden, following the manufacturer’s instruc-
tions.
