oral appliances are indicated for the treatment of Sleep Apnea syndrome. Dentoskeletal effects of oral Appliance are imperfectly assessed.~the investigators want to study dental movements by comparing three-dimensional reconstruction of the teeth and the dental articulation in patients treated for sleep apnea syndrome in our Hospital.~The study consists of an additional acquisition of three-dimensional reconstruction of teeth.~the data previously acquired during the first digital impression according usual practise will be compared to this additional acquisition.
The DO OAM study is a mono-center, interventional, prospective study carried out in CH VALENCE.~It will estimate the prevalence of dental movements in patients treated by oral Appliance for Sleep Apnea syndrome.~The investigators will used fingerprinting technique by taking multiple photographs of the teeth that allow for the three-dimensional reconstruction of the teeth~this study will provide a better understanding of dental movement caused by oral appliance
