ARTEX CP
OPEN CENTRIC
Guide pivoting lever (2) up to stop, moving the
centering axes (2 semi-axes) in, thus releasing
the centric.
Centric opened (3). Fixing of condyle balls
released. The top may be freely moved.
CLOSE CENTRIC
Move pivoting (4) lever down to stop. The two
semi-axes are guided out until softly stopping
against the condylar centre, fixing the Artex top
section in centered position. Centric closed.
Visible fixation on condylar centre by semi-axis. 2
Support in inclined
Centric closed (5). Visible fixation on condylar
centre by semi-axis.
ADJUSTMENT OF BENNETT ANGLE
Open centric (6). Release locking screw of
Bennett angle with allen key. Adjust condylar unit
from –5° to +30° by rotary button.
Fig.: Bennett angle = 0°.
Rotate Bennett angle (7) to required scale setting
by means of the rotary knob, then lock by allen
key.
Fig.: Bennett angle = 30°.
ADJUSTMENT OF CONDYLE PATH
INCLINATION
Release condyle (8) path inclination (HCI) set
screw with allen key. Adjust required angle by
rotating the condylar box. then fix HCI set screw
with allen key.
Adjustment (9) of HCI from -20° to +60°.
Read angle of inclination from front edge of rear
section (congruent with the scale).
Fig.: HCI = +60°.

SEQUENCE OF MOVEMENT
Condyle balls in centered position and during
movement with different Bennett angles (view
into condyle)
Attention
Sequences of movement in Arcon articulators
must be performed in permanent contact of con-
dyle balls (bottom part of articulator) with the
condylar box (top part of articulator). Only thus
they can be reproduced.
(10) Bennett angle adjusted to 0°. Condylar
spheres in centered position = initial position for
movements.
(11) Bennett angle adjusted to 0°. Condyle ball
guided in all three dimensions in permanent con-
tact with the condylar unit. The condyle ball may
never lose contact with the fossa, neither in cra-
nial nor mesial direction.
(12) Bennett angle adjusted to 30°. Condyle ball
in centered position = initial position for move-
ments.
(13) Bennett angle adjusted to 30°. Condyle ball
guided in all three dimensions in permanent con-
tact with the condylar box.
ARBITRARY PIN/CENTRE OF AXIS
Maxillary cranium/axis-based transfer of the
maxilla can be effected directly on the articula-
tor by adapting the facebow. Both the arbitrary
pin (14) (which reproduces the position of the ear
opening/bore of the porus buttons) and the axis
mean point can be used as a reference.
DISTRACTION
Loose screw from frontal. (15) Install distraction
to the desired value (0-3 mm) and fix it with the
screw (16).
