OCCLUSAL EQUILIBRATION BETWEEN OPTION AND CLINICAL REALITY

hinge axis in frontal plane and the possible deviations towards
the right or left side of the mandible. On sagittal closing
trajectory (closing arch) around the hinge axis of the mandible
it can be deviated towards the mesial or distal
Figure 6 When the mandible on the close line
(frontal plane) moves to the right side, its right
quadrant moves to the cheek and the left
quadrant moves to the tongue and vice versa
indicated because it removes the disagreement and
occlusal and temporomandibular joint dysfunctions
of the TMJ-dysfunction syndrome. Fully functional
maxillary and mandibular dental arches have the
role to protect a harmonious occlusal function
against parafunctional activity of neuromuscular
system: pain around the temporomandibular joints
or the masticatory muscles with or without clicking,

aches (Torii, Chiwata, 2007). Factors such as the
interocclusal distance envelope of mandibular
motion, chewing stroke, tooth to tooth relations
and determinants of occlusion can be improved
by occlusal adjustments at the level of working or
balancing quadrants.
An equilibrated occlusal function can be also
