1. A device forming a mandibular advancement splint ‘MAS’ for alleviation of snoring and sleep apnoea, the device comprising:
a pair of discrete, approximately arcuate maxillary and mandibular dentition engagement units, each having a flat face in sliding abutment with a complementary flat face of the other and an opposed dentition engagement face adapted to positively engage all or part of a maxillary or mandibular dentition, a plane of abutment of said flat faces being arranged more or less normal to a sagittal plane;
rollers located at sides and towards a posterior extremity of said mandibular dentition engagement unit;
attachment pins or lugs located at sides and towards a posterior extremity of said maxillary dentition engagement unit or the posterior extremity of said maxillary dentition engagement unit, anteriorly of said rollers by at least a maximum distance of mandibular displacement to be generated; and
a single elastic element passing around the rollers and then obliquely upwards in primary runs accommodated as a loop within a groove or channel for longitudinal movement or other than elongational displacement and the groove or channel formed in and passing completely around an anterior surface of said maxillary dentition engagement unit, shorter lengths of said elastic element passing in secondary runs from said rollers to be detachably fixed to the attachment pins or lugs of said maxillary dentition engagement unit, said device configured to cause anterior displacement of a mandible from a normal position of a temporomandibular joint in a range 5 to 10 millimetres.
