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.
