  • Patent number: 10610403
    Abstract: A dental appliance may have a pair of treatment portions and a pair of retaining surfaces that hold the treatment portions within the patient's mouth. With the treatment portions properly positioned, when the patient's mouth is in the maximum inter-cuspation position: (1) the upper canine teeth contact the upper surfaces of the treatment portions; (2) the lower teeth contact the lower surfaces of the treatment portions; and (3) no upper tooth physically contacts a lower tooth. As a result, bruxism and/or other ailments can be effectively treated.

  • Patent number: 10383758
    Abstract: The invention is a dental appliance to open the airway for individuals who suffer with snoring or sleep apnea. The appliance includes a base which will fit over the lower teeth, the upper teeth or both. It can be custom made or generic to fit many people. A key component includes a tongue restraining device. The tongue restraining device is a flexible, moveable transverse band that deforms during tongue movement such as swallowing, allowing a degree of comfort to the tongue during that movement and then because of the memory of the band, returns the tongue to its original position. A mechanism will usually be included that advances the mandible. This can be done in many ways. The tongue restraining device can be added to any existing dental appliance. Even appliances that are not for the purpose of treating snoring and/or sleep apnea.

    Abstract: Improvements in cushioned custom dental guard to be constructed with EVA instead of Polyshok. The molding process ensures that the mouth guard provides even fit on all of the teeth. The custom fit is performed by taking an impression of the upper teeth and gums of the user. The dental guard can then be constructed to ensure a proper custom fit. Each layer provides a different function to provide an ideal cushion, as well as integration of artwork that is visible through the front of the dental guard. The dental guard may include air cells or chambers. The air cells provide a cushion by compressing the air cells to absorb an impact and spread the force of the impact over a greater area. A reinforcing wire maintains the shape and distribute impact forces. The reinforcing wire is completely embedded and encapsulated within the dental guard.

The connecting portion may extend labially along the anterior teeth and associated gum region of the lower jaw, and may be sized and shaped to substantially lie out of the way so as to not impede speech of the athlete.

  • Patent number: 8656926
    Abstract: A device and method for relieving head, neck, facial, joint and tooth pain. An intra-oral device, worn over the upper or lower incisors, allows at least one opposite tooth to contact the rear wall of the device, only within the user's freeway space, and prevents upper and lower posterior teeth from contacting. The device facilitates deprogramming and releasing of the upper and lower jaw muscles. The device includes an extruded or molded shell made of a hard polycarbonate or similar hard plastic material. The internal surface of the shell may be secured in place for the user or lined with a low molding temperature thermoplastic resin, allowing the user to mold the internal aspect of the device onto and over the teeth to produce a fitted device. This relieves the stresses, strains, pains and damage that can be caused by parafunctioning of the dental neural-muscular system.

  • Publication number: 20140034066
    Abstract: A customizable scuba-diving mouthpiece for gripping with a diver's teeth, the mouthpiece including including a front member forming a horizontal passageway and a U-shaped back member with a pair of leg portions each including a thermoformable custom-moldable bite portion which in some embodiments is substantially X-shaped in cross-section along the bite-line. Upper-inner and lower-inner wall-portions of each leg portion may terminate rearwardly beside the diver's premolars and forward of the diver's first molar, thereby reducing gagging effect. The passageway may be defined by tapered inner sidewall portions defining the greatest between-sidewall-portions cross-dimension at the leg portions. A bite-limiter may be inserted into the passageway and includes a bite-limiting portion positioned for engagement with the diver's incisors to control the degree of bite and depth of tooth impressions, the bite-limiting portion having a thickness no greater than one third of a passageway vertical dimension.

  • Publication number: 20140007884
    Abstract: A mouthpiece includes a first body configured to be secured over one or more teeth of a user. The first body comprises a frame for location about at least one of a molar or a premolar of user, as a first bite pad between upper teeth and lower teeth. The first bite pad is molded in the frame while in situ in the mouth of the user and the first bite pad is formed by a PVS material. The first bite pad is in contact with at least one of a molar or a premolar of user, and the first bite pad defines an exterior shape of at least a portion of the teeth of a user. There is a similar second body with a connector between the first body and the second body and together these form the appliance for the user.

  • Patent number: 8573224
    Abstract: A method for forming a custom-molded oral appliance for positioning a user's jaw proximate to centric occlusion is disclosed. The method includes heating a thin sheet of material comprising a polycaprolactone polymer. The thin sheet of material is positioned within the user's mouth. The user's jaw is positioned proximate to centric occlusion. The thin sheet of material is molded around at least respective portions of the user's upper and lower dental arches such that each of the respective portions of the user's upper and lower dental arches form respective impressions on opposite sides of the thin sheet of material. The thin sheet of material is transitioned to a substantially non-deformable state.
