Abstract
In TMD, both excessive central inputs from the brain and excessive afferents from trigeminal receptors are working to generate and keep up muscular spasticity conditions. Hence, an interceptive, specific, and early therapeutic objective is to reach both myorelaxation and moderation of these abnormal inputs. But spastic conditions always make exact diagnoses about possible peripheral factors more difficult. Dental malocclusion or postural problems are harder to evaluate accurately. So the parafunctional habit called as severe clenching seems a “Gordian knot” to be mainly sliced through. In a second phase, the causal factors (peripheral and/or central) will be easily evaluated and eliminated by adapted methodical responses based on a mostly multidisciplinary vision.

Dental surgeons are advised that early myorelaxation combined with exercise contributes to restoring the harmonious function of stomatognathic muscles, which is essential to allow occlusal recording and rehabilitation [12]. A study in rats showed that occlusal disharmony was a factor for chronic stress. So dentist surgeons have to be aware that an overocclusion could elicite severe central neurobiological perturbances (high rate of stress neuromediators) to delay even for a long time.

This should be followed by a useful intermediate step before occlusal or prosthetic rehabilitation, consisting in a retro-incisor occlusal plan used as an individual pattern [5].

“As the cause is removed, the effect disappears.”
