Interaction Between Body Posture and Nocturnal Sleeping Disorders in Dysgnathic Patients

Laboratoire de Biomécanique Georges Charpak100 enrolled

Overview

The role of head posture has been demonstrated in patient with dentofacial deformities. However, the relationship between body posture and jaw disorders is unclear. Moreover, patients with obstructive sleep apnea have the same anatomical abnormalities than patients with dentofacial deformities. The aim of this study is to evaluate, firstly, nocturnal sleeping disorders among patients with jaw disorders. Secondly, the investigators aim to evaluate the interaction between body posture, breathing and dentofacial deformities. A polygraphy will be performed on patient with dentofacial deformities before and after correcting jaw surgery. A postural evaluation will be done using EOS imaging system and a force plate
