SEQUENCE OF MOVEMENT
Condyle ball in centered position and move-
ment (view into condylar box).
Attention:
Sequences of movement in Arcon articulators
must be performed in permanent contact of con-
dyle balls (bottom part of articulator) with the
condylar housing (top part of articulator). Only
thus they can be reproduced.
Start position:
(19) Bennett angle adjusted to 30°. Condyle ball
in centered position = initial position for sequence
of movement.
Sequence of movement:
(20) Bennett angle at 30°. Condyle ball guided
subject to permanent contact with the condylar
box on all three dimensions. This is an imitation
of the adjustment claw of the protrusion pointer.
The condyle ball may never lose its contact with
the fossa, neither in cranial nor mesial direction.
DISTRACTION
Loose screw from frontal. (21) Install distraction
to the desired value (0-3 mm) and fix it with the
screw.
COMPRESSION
(22) Lift frame top by the required compression
reading = distraction. Position models into articu-
lator. Lower frame top for compression and
retighten screw.
Fig.: Distraction set to 3 mm.
ARBITRARY PIN/CENTRE OF AXIS
Maxillary cranium/axis-based transfer of the
maxilla can be effected directly on the articulator
by adapting the facebow (23). Both the arbitrary
pin (which reproduces the position of the ear ope-
ning/bore of the porus buttons) and the axis mean
point can be used as a reference.
WARNINGS AND
!
SAFETY ASPECTS:
_ Anatomical anterior guidance
Angle of protrusion track = 40°; on lateral
movements the angle varies between 30 and
40°, according to the predetermined Bennett
angle
_ General information
Articulators are precision instruments.
Therefore, it is important to handle them
with care. Please read the following notes:
_ Do not place the articulator in a boil-out
unit, a pressure pot or an ultrasonic bath.
_ For cleaning and care, use only cleaning
agents that are suitable for light metals.
Regarding the use of the cleaning agent,
please follow the instructions of the
according manufacturer. Do not use clean-
ing agents with a pH <5 or >8 since those
might damage the anodized surfaces.
