A dental appliance having an arch plate with a chewing surface portion and a tooth contacting surface thereon. An interior and exterior sidewall extend upwardly from the tooth contacting surface. The inner sidewall, outer sidewall, and tooth contacting surface define a tooth receiving cavity that is adapted to complementarily receive teeth on an arch and fix the appliance with respect to those teeth. An outer surface is located opposite to the tooth contacting surface and defines a plane formed by high points thereon. A tongue pocket is affixed to an anterior end of the arch plate and it has an upper and lower portion. The upper portion is integrally connected with inner sidewall and the lower portion is opposite to the upper sidewall. The tongue pocket is concave on its inner surface and on its lower portion has outer ramped surface. The outer ramped surface terminates in an incisal step.
