The appliance includes a base member 12 having a generally U-shaped horizontal portion 12a with opposing posterior sections and an anterior section disposed between the posterior sections. The anterior section has an arcuate curvature substantially matching the curvature of the dental arch of most wearers. The appliance includes over-molded anterior occlusal pads and molar pads 14 that are attached to the upper surfaces of the base member 12. An over-molded anterior flange 16 is attached to a vertical portion of the base member. The anterior occlusal pads, molar pads and anterior flange are formed from a thermoplastic material having a Vicat softening temperature below that of the base member. After heating the appliance to above the softening temperature of the over-molded portions, the anterior occlusal pads, molar pads and anterior flange may be custom fitted to the upper teeth and gums of the wearer. |
