| Research Abstract |
To investigate the influence of craniofacial morphology and malocclusion to the posture, especially head and bodily movements, the head and bodily movements were measured by system of six-degrees jaw and bodily action analysis apparatus, and EMG in subjects with mandibular deviation.
1. In subjects with normal occlusion, the frequency of head movements was 96.5±5.6% in sitting position and 96.2±3.6% in standing position.
2. In subjects with mandibular deviation, the frequency of head movements was 76.9±37.6% in sitting position and 60.5±31.1% in standing position.
3. The frequency of bodily movements in subjects with normal occlusion was 87.4±10.8% in sitting position and 81.1±16.1% in standing position.
4. The frequency of bodily movements in subjects with mandibular deviation was 51.8±17.7% in sitting position and 37.8±13.6% in standing position.
These results suggested that the influence of occlusal contact accompanied by mandibular deviation was not only region of superior limb but also inferior limb. It was concluded that the asymmetry of occlusal contact and craniofacial morphology might affect the collaboration of posture control, especially bodily movements.
