Intraoral appliance to improve voice production

Abstract

An intraoral appliance which when worn by a singer or other vocalist acts to improve the quality of the voice and increase its power. The appliance is constituted by a pair of spacer pieces molded to conform to select teeth in the oral cavity of the vocalist, the pieces being seated on molars or other teeth on opposing sides of either the upper or the lower dental arch. The smooth head surfaces of the pieces are raised slightly above the teeth on which they are seated to prevent the arches from meeting and causing the mandible supporting the lower arch to slide forward relative to the maxilla to an extent limited by the parameters of the temporomadibular joint. The displaced mandible serves to release tension on the muscles of the head, neck and chest associated with the mandible, giving rise to greater and more efficient respiration, a relaxation of the hyoid bone supporting the tongue and its muscles and from which the larynx is suspended, and a relaxation of the vocal cords of the larynx. The changes in tongue, cheek, lip and cranial bone positions resulting from displacement of the mandible, enhance the resonance of the voice and impart greater power thereto.
