In recent years a portion of the scientific literature and clinical trials (FDA approved clinical trials, Academic research papers,TMJ.org,) from all over the world have shown an anatomical-functional and pathophysiological connection between craniomandibular and craniocervical dysfunction, connecting various zones of the organism in a single tonic-postural system. This research is based on biomechanical concept theory, Molar Lever conception and Domino Effect reaction in organism. According to this theory, when dental support is not adequate the skull tends to collapse. Thus the top cervical vertebrae gets miss-aligned and the skull tilts and moves away from a symmetrical and balanced position on top of the shoulders. When postural collapse affects, strains, compresses and twists the brain stem, the body reacts with neurological symptoms. They are automatic unconscious reflexes that do not make it past the brain stem to the conscious brain. So, called Dystonia: involuntary asymmetric muscle contractions. This study shows new vision in the treatment of cervical dystonia, as a bio-mechanical approach. Research is based on clinical cases using Starecta Method, modified dental splint –The Rectificier- to solve a postural problems. Each case is individual and needs several diagnostic methods (Postural Platform, Stabilometric Platforms, X- rays, MRI Scan, Face Photos) according to the diagnoses. Statistics is based on multi analysis and effectiveness of this conception. You can solve a postural problem only if you know “precisely” how the biomechanism works and therefore the exact relationship between teeth, occlusion and posture.
