relationship between occlusion and posture

The stomatognathic system includes the relationship between teeth, masticatory muscles and temporomandibular joints with its relation with body and head posture. Aim of the study: This Systematic review is to research the relationship between occlusion and body posture. Materials and methods-Study design: This is a literature systematic review which is done after collecting more than 10 previous papers. Inclusion criteria: Papers explaining dental occlusion in details and its correlation with body and head posture. Exclusion criteria: Papers about occlusion focusing on occlusal splints and lab work. Conclusion: There is a strong relation between dental occlusion class, head, and body posture through PDL and the trigeminal nerve in the brain. Accordingly, the occlusion affects the posture and, more importantly, the position of the condyle in the temporal fossa. It was always believed that condyle position comes first then the occlusion, but it is the other way around.
