Ivoclar Vivadent Stratos 300 - Manual (Page 11)

5.1.2 Centric fixation lock (4.1) closed
In this position, the two frames of the Stratos 300 can no longer
be separated and the articulator is fixed in the centric position.
The centric fixation can be opened by applying slight pressure.
This greatly facilitates handling for the user.
5.1.3 Centric fixation (4.1) locked
To lock the centric fixation completely, e.g. if the articulator has to
be transported, or if no movements are desired, pull the joint axis
into the precisely defined, final position by turning the centric
screw to the right.
Loosen the centric fixation before carrying out
masticatory movements.
5.2 Protrusion
5.2.1 Protrusive movements can be simulated if the centric
fixation (4.1) is open, according to the schematic below. The angle
of the protrusion path can be adjusted to be more acute or flat
(0–60°) by setting the respective protrusion angle.
Protrusion angle:
By loosening the P knurled screw (5.1), the protrusion angle may
be adjusted and fixed with the P angle indicator (5.2).
The set protrusion angle can be read off at the top edge
of the P angle indicator (5.2).
