    • A unitary plural-material, interocclusal dental appliance (10) is disclosed for use in connection with orthodontic/orthopedic treatment of the teeth and jaws of a patient's mouth. The appliance includes a first region (14) made from a first material that provides a relatively hard expanse with first and second surfaces, and with the second surface being contactable by one such set of teeth. The second surface may be constructed with a substantially planar shape, or with a shape conforming generally to the cusps of such one set of teeth. A second region (16) is joined to the first region (14) and is made from a second material that provides a relatively soft, persistently resilient enclosure for the other such set of teeth. Additionally, a curable composition for making a soft, persistently resilient dental appliance is disclosed and it includes a polymer component including butyl methacrylate monomer.
