Abstract

Objective: Dental occlusion may relate to general conditions including posture, however, there is little evidence of jaw deformities and general posture. The objective of this study is to assess the relationship between skeletal jaw asymmetry and head/body posture. Methods: Forty-five mandibular asymmetry patients were included in this study. Lateral mandibular deviation, head inclination, and vertebrae deviation were studied before and after orthognathic surgery. Results: There was a correlation between mandibular deviation and head inclination, however, there were no correlation between vertebrae deviation and head inclination. On average, head inclination and vertebrae deviation were not changed after orthognathic surgery. But, for cases with a large deviation, they improved after surgery. Conclusions: Lateral mandibular deviation influences head and spine posture, in most cases reversibly.
