Brief summary
Study over muscular stretching to reduce pain the oral cavity.
Detailed description
It is a current opinion that muscular stretching is able to reduce pain and to allow increase of the opening excursion at the joints. To investigate this possibility in the face, the investigators developed a method of stretching associated with large dynamic jaws during chewing using a special device (Spring Device ®) for ten minutes, allowing the muscles of the oral cavity to relax. The height of the bite was set as two-thirds of the maximum opening (max. 2 cm.) of the mouth at rest (without forcing) thus avoiding maintaining the head of the condyle at maximum aperture for a long time. The subjects were then analyzed by means of kinesiography to determine the changes in the vertical dimension. Increasing stretching produces neuromuscular relaxation and a reduction of pain. This study showed that this therapy induces oral and extraoral pain reduction and increases neck mobility and mouth opening. The stimulation of trigeminal receptors is an important drive for therapy in the trigeminocardiac reflex (TCR).

Primary
| Measure | Time frame | Description |
|---|---|---|
| Mandibular stretching influences the temporomandibular disorders | up to 24 weeks | It is a current opinion that muscular stretching is able to reduce pain and to allow increase of the opening excursion at the joints. To investigate this possibility in the face, the investigators developed a method of stretching associated with large dynamic jaws during chewing using a special device (Spring Device ®) for ten minutes, allowing the muscles of the oral cavity to relax. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| mandibular stretching induces a reduction of facial contraction and decrease of heart rate | up to 24 weeks | Those effects are described as trigemino-cardiac reflex. Application of a spring device (which consists of thin sheet of surgical steel bent in to a loop) induces a decrease of blood pressure and heart rate. |
