A water sports nasal guard prevents unwanted contaminated water from entering a user's nostrils. The water sports nasal guard includes a mouth guard, an upper tongue shield, a lower tongue shield, and a nostril shield. The mouth guard allows the user to bite down on the water sports nasal guard, thereby upholding the nostril shield against the nasal passages of the user. The nostril shield presses up against the openings of the user's nasal passages. The mouth guard further includes an arch-shaped body, an upper teeth receptacle, and a lower teeth receptacle. The arch-shaped body positions the upper teeth receptacle and the lower teeth receptacle opposite to each other, both of which accommodate the upper teeth and lower teeth of the user. The upper tongue shield and the lower tongue shield prevent the user's tongue from coming between the teeth of the user and the mouth guard.

This invention is an athletic protective mouthpiece and lip shield apparatus used in contact sports and is designed to attach to a helmet's chin strap. The mouthpiece, Air Channel, and Lip Shield structures are particularly designed to comfortably protect both upper and lower jaw of the athlete while removing unwanted impact stress from the front teeth (Incisors) and placing such stress to the stronger Cuspid and Molars regions of the athlete's dentures. This invention solves the problems of airflow restriction and impact stress of the front teeth from other athletic mouthpieces by removing the position of the Incisors from atop the breathing orifice to behind said orifice, whereby providing an improved larger non-condensing airway for the passing of unrestricted airflow. The apparatus is designed to pivot and operate by way of an attachment strap affixed to the Lip shield and fitted into an opening on the helmet's chin strap.

A mouthguard configured to receive wireless audio signals and transmit these audio signals to a user via bone conduction may include one or more wireless antenna, a controller, a power storage device, an external power and/or data port, and one or more bone conduction speakers. The mouthguard is inserted in the user's mouth to protect against dental injuries as well as to enable communication between the user and a remote audio source. The inner surface of the mouthguard contacts the user's teeth for transmitting audio content to the user and audio content is transmitted to the wireless antenna of the mouthguard.

A mouthguard includes a curved member that is receivable within the mouth of a user, a connector that is engageable with the curved member or affixed to the curved member, and a retaining device that is coupled to the connector and is affixable to an item worn by the user. Ther retaining device includes mating fasteners that are situated on the connector and that are engageable with one another. A mouthguard holder includes an elongated member having a slot or opening into which a mouthguard is received and a retaining device that is coupled to the elongated member. The retention device includes a clip or fasteners that are coupled to the elongated member. The clip is affixable to an item worn by the user.

Systems for protecting and repositioning teeth are provided. In some embodiments, a system includes a tooth repositioning appliance and a covering guard. The tooth repositioning appliance can have a plurality of tooth-receiving cavities shaped to reposition teeth of a patient. The covering guard, when worn by the patient and coupled with the tooth repositioning appliance, can provide protection against impact-induced injuries. The covering guard can have a guard segment that covers at least a portion of the tooth repositioning appliance. A combination of the covering guard and the tooth repositioning appliance can include an occlusal portion disposed between a plurality of upper and lower teeth when worn by the patient. The occlusal portion can have a compliance selected to provide impact absorption during an impact forcing the lower teeth into the upper teeth.

The present technology relates to methods for fabricating mouth guard systems. In some embodiments, for example, a method includes fabricating an aligner having a polymeric shell including a plurality of tooth-receiving cavities shaped to reposition teeth of a patient. The polymeric shell can be shaped to cover an occlusal surface of the teeth when the aligner is worn by the patient. The method may further include fabricating a mouth guard shaped to protect the teeth, the mouth guard including a plurality of cavities shaped to receive the teeth and accommodate the aligner when worn on the teeth, and an occlusal portion connected to the plurality of cavities. The occlusal portion may be shaped to reduce impact forces on the teeth. The mouth guard may be configured to be removably coupled to the aligner.
