An ideal case is suggested when the CO corresponds to the CR (Fig. 2). A deflective occlusal
contact (habitual contact position) always occurs when a dental prosthesis has been adjusted on
the high or low side (infra-occlusion (Fig. 4) Fig 5.

Every dental procedure changes the patient’s occlusion and consequently causes a new habitual
occlusion, making a concealed high spot difficult to locate. At this stage, the temporomandibular
joints, the desmodont, and the teeth are exposed to increasing load factors. If these symptoms are
not recognized in time, altered contact guidance result in wear facets (Fig 6). The
temporomandibular joints and neuromuscular system are also exposed to increasing stress caused
by malocclusion. The articulate disc will be compressed and the musculature hardened, thus
causing pain.

There are several causes of Cranio Mandibular Dysfunction,
which require a combination of dental and medical practitioners
(dentist, surgeon, physiotherapist, etc.) to work together to
eliminate the pain.

When patients are tense, they adopt a poor habitual occlusion
that deviates from the centric relation (CO/CR) due to
malpositions of the teeth or jaws. This deviation influences all
additional treatment steps.
With centric records, it is often difficult to determine the centric
condylar position, especially in patients with neuromuscular
disorders. Deprogramming the neuromuscular system is also a
good idea for testing the occlusal relationships. There are various
methods for deprogramming the stomatognathic system
neuromuscularly, such as biting on two moistened cotton pellets,
a JIG splint or even special manual grips (Dawson grip) as well
as two hydrostatic bite aids. Aqualizer and GELAX ® are
especially effective. These temporary occlusal splints are filled with water or hydrogel to
equilibrate all interfering high spots.
