The rotating condylar path may be inclined
forward or backward as the rotating
condyle moves outward. This forward and
backward inclination of the rotating
condylar path in the horizontal plane has
its principle effect on the intermeshing of
the working inclines of cusps on the work-
ing side (ridge and groove direction).
The Dénar
®
Mark II Semi-adjustable
Articulator has the rotating condylar path
reset to the average anatomic inclination
(out and backward 25 degrees).
Figure 26A illustrates a frontal view of
molar tooth relations in a right lateral
mandibular movement. Although the rotat-
ing condyle moves straight outward the
functioning tooth inclines on the rotating
side have a slight downward inclination
due to the fact that the path of movement
of the orbiting condyle is inclined remark-
able downward.
