Abstract
Recently, the number of patients with unidentified complaints has increased. Since occlusal disharmony is a cause of unidentified complaints in some patients, investigation of the relationship between occlusion and posture is important. In this study, we investigated improvement in occlusion with changes in posture. As a result, improvement in systemic symptoms was a two-stage process, in which improvement in the head position was obtained in the first stage. and improvement in the right rotation posture was obtained in the second stage. Furthermore, it was revealed that posture related to occlusion was classified into posture when diseases occurred, and habitual posture due to life-style and work circumstances.
