Mécanismes posturaux Volume 74, issue 2, 76e réunion scientifique de la S.F.O.D.F. – La dimension verticale (1re partie)


The specifically human development of the oropharynx and the nasal valves leads to mechanical instability of these structures under negative pressure so that regulation of the upper airways patency is needed. Among the involved mechanisms, some deal with pharyngeal mechanics and craniocervical posture, some with tongue and linguopharyngeal posture regulations; others deal with facial envelope mechanics, and labionasal or labiomental posture regulations. The application of these notions to dentofacial orthopedics is a very efficient one.
