ABSTRACT:
An inter-incisal non-voluntary orthodontic device intended for use in conjunction with overbite corrective braces. The device includes plate of thermoplastic material positioned over selected upper anterior teeth that acts to prevent contact between the selected upper anterior teeth and the opposing lower anterior teeth. The plate by preventing contact between the anterior upper and lower teeth also prevents occlusion between the upper and lower posterior teeth. The plate is anchored to selected upper molars in such a way that the patient cannot easily remove the plate. The plate is connected to selected upper molars, preferably the first molars at sheaths connected to molar jackets used to anchor the patient's braces. Additional anchoring is provided by a ligature through an aperature in the front of the plate and under the brace wire.
