Abstract
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.
Claims20
A device for positioning upper and lower jaws, including a pin associated with one of the jaws and a follower associated with the other jaw, the follower having an engagement surface which moves over the pin to advance a first of the jaws relative to a second of the jaws when the jaws are closed;
- wherein the pin is adapted such that rotation of the pin allows for adjustment of the distance by which the first jaw is advanced relative to the second jaw, and
- wherein the device is configured such that the operation of the device is driven by the movement of the jaws as the jaws are closed.
A mandibular advancement device which comprises both an upper base plate and a lower base plate for fitment with a respective upper and lower jaw, the base plates having co-operating portions that engage during closing of the jaws to cause protrusion of the lower jaw;
- wherein the co-operating portions are arranged to enable lateral movement between the base plates during the closing of the lower jaw;
- wherein the co-operating portions are located on either side of each of the base plates;
- and
- wherein the device is configured such that the operation of the device is driven by the movement of the jaws as the jaws are closed.
A mandibular advancement device which comprises both an upper and a lower base plate, wherein the upper base plate incorporates two side followers, which are located on either side of the upper base plate, each side follower including a curved engagement surface that co-operates with the lower plate to enable controlled forward movement of a lower jaw as the upper and lower base plates are moved together;
- wherein each of the side followers is shaped so as to push on to a respective opposing adjustment mechanism, located in the opposing outer side of the lower base plate;
- and
- wherein the device is configured such that the operation of the device is driven by the movement of the jaws as the jaws are closed.
