Sakaguchi K, Mehta NR, Abdallah EF, Forgione AG, Hirayama H, Kawasaki T, Yokoyama A. Examination of the relationship between mandibular position and body posture. Cranio. 2007 Oct;25(4):237-49.
Evaluating 45 asymptomatic subjects Sakaguchi et al concluded that:
1. Body posture was more stable when subjects bit down in centric occlusion.
2. Changes in body posture affected occlusal force distribution.
3. Altering body posture by changing leg length shifted the occlusal force distribution to the same side that had a heel lift.
In a clinical setting, when dental occlusion is developed and finished, body posture should be taken into account.
If a patient has a leg length discrepancy, hip rotation or any other problem altering body posture, occlusal contacts may differ as the patient stands up and starts walking.
