6.3 Average orientation of edentulous
cases with the horizontal guide
6.3.1 Return articulator to the initial set position
– See 6. 1 . 1 for description
Remove incisal indicator (1.3).
6.3.2 Mark and bisect the
Trigonom retromolare on
the mandibular model.
Bisect the distance
between the upper and
lower mucolabial folds and
set the symphysis fork
(41.1) of the horizontal
plane on the resulting
value.
Using the resulting values,
orientate the mandibular
model to the horizontal
guide and hold it in place,
e.g. with a rubber band.
6.3.3 Mount instrument
carrier to the upper frame
(2.3)
Fasten horizontal guide in
place by means of the
knurled screw of the
instrument carrier.
Insert horizontal
guide completely
into the instrument
carrier. After that,
apply some plaster
on the model and
base block and close articulator slowly.
6.3.4 Next, orientate maxillary model as usual.

6.4 Average orientation of dentulous
cases with the horizontal guide
6.4.1 Return articulator to the initial set position
– See 6. 1 . 1 for description
Remove incisal indicator (1.3).
6.4.2 Transfer maxillary
mesial contact area
vertically to the mandibular
model. Mark the tips of
both distobuccal cusps of
the lower second molars. If
these molars are missing, the first molars may be
used instead.
– Put mandibular mesial
contact area behind the
incisal tip of the
symphysis fork.
– Adjust horizontal guide in
such a way that the rear
edges barely cover the
marked cusps of the second molars and align
symmetry.
– The retromolar pads are used as reference points for
free-end surfaces, similarly to the Trigonum
retromolare in edentulous cases.
Subsequently, attach horizontal guide to the model
with e.g. wax or a rubber band.
6.4.3 Mount instrument
carrier to the upper frame
(2.3).
Fasten horizontal guide in
place by means of the
knurled screw of the
instrument carrier.
Insert horizontal guide completely into the
instrument carrier.
After that, apply some
plaster on the model and
base block and close
articulator slowly.
6.4.4 Next, orientate maxillary model as usual.
