Abstract: An appliance for use in a method of reducing facial aging and/or oral parafunctional activity comprising two parts, each comprising a composite structure comprising: a first layer formed of a durable, resilient, elastomeric material comprising a cured thermoset rubber and which in use contacts the occlusal biting surfaces of the posterior teeth; and a second layer formed of a durable, non-deformable material having a softening point over 100° C. which provides a bite plate; wherein the second layer of each part is provided with a protrusion formed of durable, non-deformable material having a softening point over 100° C. which is positioned such that in use the protrusion extends from the surface above at least a part of the first and/or second molar teeth which are in contact with the first layer. A method of making the appliance, a kit of parts, and methods of use are also disclosed.

Abstract: An appliance for use in a method of reducing facial aging and/or oral parafunctional activity e.g. bruxism, comprises two parts, the parts intended in use to contact the posterior teeth on respective opposite sides of either the upper or lower jaw, each part comprising a composite structure comprising: iii) a first layer (2) formed of a durable, resilient, elastomeric material comprising a cured thermoset rubber and which in use contacts the occlusal biting surfaces of the posterior teeth; and iv) a second layer (3) formed of a durable, non-deformable material having a softening point over 100° C. and which in use provides a bite plate; wherein the second layer of each part, that has a substantially planar first surface, is provided with a protrusion (5), formed of durable, non-deformable material having a softening point over 100° C.

Abstract: A mass produced universal dental appliancee (1) comprises two parts, the parts intended in use to contact the posterior teeth on respective opposite sides of either the upper or lower jaw, each part comprising a composite structure comprising: i) a first layer (2) formed a durable, resilient, elastomeric material having a softening point in the range from 35 to 100° C. and which in use contacts and grips the occlusal biting surfaces of the posterior teeth; and ii) a second layer (3) formed from a durable, non-deformable material having a softening point over 100° C. and which in use provides a bite plate; wherein the second layer of each part is provided with a protrusion (5), formed of durable, non-deformable material having a softening point over 100° C.
