A mandibular advancement device is proposed which comprises both an upper and a lower base plate, whereby engagement of the plates during closing of the jaws causes protrusion of the mandible and allows relative lateral movement between the jaws. In one particular form the invention relates to a device for positioning upper and lower jaws, including a cam associated with one of the jaws and a follower associated with the other jaw, the follower having an engagement surface which translates across the cam to advance one of the jaws relative to the other as the jaws are closed.
L'invention concerne un dispositif d'avancement mandibulaire qui comprend une plaque de base supérieure et une plaque de base inférieure, grâce à quoi l'engagement des plaques lors de la fermeture des mâchoires entraîne une protrusion de la mandibule et permet un mouvement latéral relatif des mâchoires. Dans une forme particulière, l'invention concerne un dispositif destiné à positionner les mâchoires supérieure et inférieure, comprenant une came associée à l'une des mâchoires et un suiveur associé à l'autre mâchoire, le suiveur présentant une surface d'engagement qui se translate le long de la came afin de faire avancer une des mâchoires par rapport à l'autre, lorsque les mâchoires sont fermées.
