Relief for some may only be temporary when the common splint and deprogramming appliance are often casually administered as band aids to mask the deeper underlying issues of the bodies unbalanced musculature that desires a more specific terminal contact position (the human bite) to support the lower jaw to upper jaw during resting and functioning modes. Balanced muscles of the head and neck occur best when a comfortable and balanced bite is achieved to satisfy the central nervous systems requirements of fine sensory input of the trigeminal system.
The myo-trajectory is foundational to effective TMD muscular relief. Muscles seek a neutral position in the antero-posterior relationship. Most clinicians focus on vertical dimensions but do not adequately nor specifically address all the 6 dimensions of jaw relationship (antero-posterior, frontal/lateral, vertical, pitch, yaw and roll).
If one open the bite vertically, and the mandible is still functioning posterior to the isotonic closing path of where the mandible should really be, the muscles will strain and any occlusal adjustments will not be properly synchronized to the proper muscles relationship. This is a common problem for patients. Dentist don’t measure these relationships so how would anyone really know if the occlusal adjustments (equilibrations) done in the mouth or on an appliance is truly matching calm and isotonic muscle relationships?
