Obstructive sleep apnea and its associated risk factors can now be more easily identified by specialists in the oro-facial zone, not only through clinical diagnosis but also with the help of new imaging tools such as CBCT or scanners. Orthodontists, who intervene at the intersection of the aero-digestive spheres, have long had an excellent diagnostic tool called Cephalometrics, which they systematically use on a daily basis. For this reason, they are best equipped to detect early morphological signs of possible apneas or indications that an individual may be prone to obstructive sleep apnea and/or hypopnea, and to recommend more specific examinations and consultations, including a Polysomnography.
