BIOMECHANISM OF TMJ

    1. CHANGE OF CERVICAL VERTEBRA & PELVIS
        
    From DENTAL DISTRESS OF A.C.FONDER P.19
       Any disturbance of the counteracting balance of the 136 upper torso muscles alters the  posture of the atlas & axis.
     Excessive free way  space and malocclusion that produce bruxism and muscle spasms are the main cause of the upset of this antagonistic muscle  balance.

    The malposturing of c1(atlas) and axis (c2) through dental malocclusion and  the resultant mandibular dysfunctioning, torquers the dura mater because of the frontal & dorsal attachments to C1, C2 and C3 The muscular imbalance and resultant torquing of the Dura mater cause scoliosis, cervical hypolordsis (military neck), thoracic hyperkyphosis  (humpback), rotation of the pelvis causing uneven  leg length, etc. when these 136 muscles are allowed to assume a more physiologically balanced relationship by the correcting of the  malocclusion and improper vertical (excessive free space) the head immediately assumes an upright posture, the shoulders level off and the pelvis rotation cease allowing the leg length to equalizes. The overall bodily posture dramatically normalizes.
     These changes are instantaneous and can be reversed by altering the
    occlusal support.

    2. CHANGE OF SKULL BY JAW POSITION
      
       From THE DENTAL DISTRESS SYNDROME by A.C.FONDER P.33-34
          

     
    The dura mater is a thick and dense inelastic membrane that envelops the brain and medulla spinalis.
    Which is continuous membrane  that surrounds the brain, passes out the base of the skull, attaches to  the first three cervical vertebrae, and continues down the spinal cord where it finally attaches to the sacrum.

    we swallow twice a minute when awake and once every minute during sleep If we subjected the teeth to only one pound of pressure per square inch with each act of swallowing the dental structures would absorb approximately one ton of intermittent pressure daily. However, the average person exerts at least three and one half pounds pressure  during swallowing, While the habitual clamper and nocturnal  bruxer far exeed this norm(Garliner 1973). So stressful malocclusion results in many tons of intermittent  dental stress , in erroneous feedback, the constantly upsets th balance of the body's systems until the dentist intervenes.
