Predictive Factors for Occlusal Changes in Obstructive Sleep Apnea Treatment With Mandibular Advancement Appliance

In this research, participation in the protocol seamlessly integrates into routine care at the Odontology Department of the University Hospital of Toulouse. The visits include the provision of the orthosis at 3 weeks (T1), with EMGs and digital occlusal analysis. The 6-week follow-up visit (T2) adjusts therapeutic propulsion, subjectively resolving symptoms related to OSAS. At the T0 visit, the researchers collect the polysomnographic monitoring before fitting the orthosis (carried out in the patient's reference sleep laboratory) to assess treatment efficiency. The end-of-research visit (6 months after T1) comprehensively collects data, including questionnaires on stress, anxiety, sleep quality and quantity, oral habits, temporo mandibular dysfunction pain, and quality of life. Moreover, the researchers collect the polysomnographic monitoring after 3 months fitting the orthosis (carried out in the same patient's reference sleep laboratory than before fitting the orthosis).
