R TMCC Pattern (Right Temporomandibular Cervical Chain)

TMCC: Temporomandibular Cervical Chain

The other polyarticular chain described in Postural Restoration Institute ®  is TMCC (Temporomandibular Cervical Chain). The main function of the TMCC is;

  • to control your neck
  • to provide stability for the neck during respiration
  • to provide support for the scapula
  • to provide support for the voice box
  • to provide the base for your skull and jaw (Temporomandibular joint)

The dominant pattern is the right TMCC pattern to compensate

Muscles: Temporalis (ant. fiber), Masseter, Medial pterygoid, Rectus capitis posterior major, Obliquus capitis, Rectus capitis anterior, Longus capitis, Longus colli

The right TMCC pattern is often associated with the Left Sideband of the cranial strain. As you can see from the picture below, the pattern affects the jaw (Temporomandibular joint), occlusion, as well as alignment of the teeth.

Left sidebend cranial strain

The other common cranial pattern associated with the Right TMCC pattern is the Right torsion.

Symptoms often associated with Right TMCC are: 
  • TMJ disorders such as:
    Jaw pain, difficulty chewing, and clicking and locking of the jaw joint are some of the symptoms
  • Occlusion issues (although it is not a scope of physical therapy) such as: 
    • Open bite, crossbites, crowded teeth, intorsion
  • Airway restriction due to the position of the cervical spine, tongue, jaw, and muscular imbalances
  • Autonomic imbalance (including direct stress on the vagus nerve)
  • Headache 
  • Voice production issues due to mechanical dysfunction or the vagus N. dysfunction 
  • Sphenobaisier Symphysis dysfunction1
    • Dysfunction of the endocrine system
    • Dysregulation of internal processes (Sensory Integration issues)
    • Impaired cerebrospinal fluid (CSF) flow
    • Decreased or imbalanced motion of the craniosacral system
