Mandibular Advancement Device

A mandibular advancement device which comprises both an upper and a lower base plate for fitment with a respective upper and lower jaw, the base plate having co-operating portions that engage during closing of the jaws to cause protrusion of the mandible.

The device as claimed in claim 16, wherein the side barriers form a tapered channel to guide the first and second cooperating members into alignment.

A mandibular advancement device which comprises both an upper and a lower base plate, each with a specific attachment apparatus, wherein engagement of the attachment apparatus during closing of the jaws causes protrusion of the mandible and allows relative lateral movement between the jaws wherein one cooperating member is in the form of a tubular section extending laterally between the jaws and the other cooperating member is in the form of a specifically shaped surface arranged to contact with an outer surface of the tubular section.

A mandibular advancement device which comprises both an upper and a lower base plate, wherein the upper base plate incorporates two side plates, which are located on either side of the upper base plate, each side plate 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.

A mandibular advancement device which comprises both an upper and a lower base plate which engage during closing of the jaws to cause protrusion of the mandible and allow relative lateral movement between the jaws, wherein each of the base plates has magnets mounted therein arranged so as to establish a magnetic repulsion between the magnets which opposes the dropping of the jaw and enhances the lower jaw protrusion.

A mandibular advancement device, substantially as hereinbefore described with reference to the accompanying drawings and/or examples.
