N2 - Introduction: The purpose of this study was to examine whether a unilateral occlusion block, using a 1 or 2 mm thick silicone panel, can significantly change the upper part of the body posture.Materials and methods: This study was carried out with 38 adults without remarkable discomfort in the temporomandibular system or body movement apparatus. The measurement of the upper part of the body posture was performed with a three-dimensional back scanner. Every test person placed the 1 or 2 mm thick silicone panel systematically between the left/right premolars. The statistical comparison of the measuring data was carried out between the reference measurement and the provoked lower jaw position.Results: If the occlusion was changed dextrally (to the right) or sinistrally (to the left) by the silicone panel, the rotation in the shoulder area improved (right 1 or 2 mm: P = 0.00; left 1 mm: P = 0.00) in comparison to the habitual starting position. With a dextral occlusion disruption by 1 mm of silicone, the pelvic rotation also changed (P = 0.05).Conclusion: A unilateral occlusion block in the premolar region has an influence on the upper body rotation in the standing position, particularly in the shoulder area. Thus the results demonstrate functional relationships between the chewing and the movement system, which may explain complaints in one of the subsystems influenced by therapeutic measures in an otherwise unaffected system.
