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.

Abstract: An oral appliance and method for reducing snoring including upper and lower mouthpiece portion, each of which having a rigid structural core and a relatively soft outer portion which may be conformed to fit the upper teeth of the user. The upper and lower mouthpiece portions are first mounted on a holder with the upper mouthpiece portion positioned forward a desired offset amount from the lower mouthpiece portion (preferably about 3.0 mm). The entire assembly is then heated and the outer soft material of the upper and lower mouthpiece portions softens and may be placed in the mouth to permit the mouthpiece portions to be conformed to the upper and lower teeth. Once the upper and lower mouthpiece portions have been properly fitted, the assembly is removed from the mouth and allowed to set into a permanent state. The upper and lower mouthpiece portions are then removed from the holder and attached directly to one another without any offset therebetween forming the full mouthpiece.

Abstract: A spacer for elevating occlusion position is composed of a plastic material which can be deformed by occlusion pressure; and a plurality of ball members having a predetermined diameter.

The mouthpiece, which is designed for use over the upper set of teeth of the wearer, includes an inner peripheral wall, an outer peripheral wall, and a connecting wall, the inner surfaces of which define a channel. The occlusal surface of the channel is more narrow in the anterior region and becomes more broad as one moves posteriorly so as to accommodate the non-uniform widths of the various teeth. In addition, the occlusal surface of the channel becomes progressively more concavely-shaped as one moves posteriorly from the first bicuspid tooth to accommodate the increasing convexity of the posterior teeth.

Abstract: A dental orthosis is provided for use in the treatment of snoring. The upper portion of the device defines a trough for receiving some of the upper teeth of the patient. The rear wall of the trough is truncated so that the device can accommodate both narrow and wide dental arches so that one size of the device can accommodate substantially all users. Once inserted into the mouth the device snugly engages the upper teeth, particularly the front teeth, and remains positioned independent of natural motions of the lower jaw. The lower portion of the device is formed into a ramp structure whereby natural jaw motions result in the engagement of the lower teeth with the ramp, which will cam the lower jaw into a more forward position.

Abstract: A bite plate is provided to protect a user's teeth from damage due to teeth grinding and/or long term interdigitating pressure, as during cervical traction. The device defines a trench for receiving at least some of the upper teeth of a user and is self fitting to accommodate both narrow and wide dental arches.

Abstract: A thermoplastic mouthguard has a U-shaped base with top and bottom sides and upward inner lingual and outer labial walls forming a channel for the upper jaw teeth having posterior and anterior portions. Occlusal posterior pads are on the bottom side of the base along the posterior portions of the guard to space apart the anterior teeth of the lower jaw from the anterior portion of the bottom side of the U-shaped base and to lessen pressure and possible impact forces exerted at the temporomandibular joint. Occlusal impact chambers are located within the occlusal posterior pads for shock dissipation and absorption. Anteriorly directed ridges are located along the bottom of the impact surfaces of the occlusal posterior pads for custom fitting of the mouthguard and tending to move the lower jaw anteriorly when a force impact is imposed upon the lower jaw. An anterior impact brace is located along the anterior portion of the outer labial wall.
