Examples of a dental orthotic guard and protection device are disclosed. The device is re-usable and can be used by users with or without braces. The protection device comprises a body shaped to correspond to user's dental arch and an aerating trough formed in the body such that it rises upward from its surface. The aerating trough has a plurality of openings to allow fluid circulating in and out through the trough to prevent fluids accumulating on a surface of the protector and provide free air flow. The dental orthotic can further comprises a U-shaped guard with top and bottom surfaces that are substantially flat such that the guard sits flat on top of user's teeth to provide fluid flowing between the user teeth and the guard. The dental protector and guard can be connected as a single piece for use as dental orthotic device in small children.

An articulator provides for a wearer to bite it between the teeth in the upper jaw and the teeth in the lower jaw. The articulator includes an upper brace and a lower brace formed integrally; whereas, an occlusion unit is formed between the upper brace and the lower brace, thereby providing for biting by the wearer. The front edges of the upper brace and the lower brace are connected to a protector through a connector. When the wearer bites the articulator, the protector is disposed on an outer edge of the lips for protection. An exhalation opening is formed between the braces and the protector, and is provided with a movable plate that is flipped outward. Therefore, when the wearer bites the articulator, he or she can carry out a respiratory training by inhaling through the nose and exhaling through the mouth, thereby increasing the vital capacity effectively.

A mouthguard which has a unique shape and design which not only facilitates air passages so a player can breath while the mouthguard is in the player's mouth and protecting the player's teeth, but also has additionally has a flavoring embedded within the mouthguard, preferably on the base on which the player is placing his upper row of teeth so that in addition to protection, the mouthguard has an attractive flavor which can be tasted by the player as the player bites down on the mouthguard.

A mouthguard according to an embodiment of the present disclosure includes a teeth engagement portion having a medial surface. An anterior surface is coupled to the teeth engagement portion opposite the medial surface. A first breathing channel extends from the anterior surface to the medial surface. A second breathing channel extends from the anterior surface to the medial surface. A third breathing channel extends from the anterior surface to the medial surface. A first interior wall is disposed between the first breathing channel and the second breathing channel. The first interior wall is configured to be aligned with a first upper incisor of a wearer. A second interior wall is disposed between the second breathing channel and the third breathing channel. The second interior wall is configured to be aligned with a second upper incisor of the wearer.

An apparatus and methods for air filtration are disclosed. The apparatus includes a body and first and second replaceable filters. The body of the apparatus further contains an air-exchange assembly and a filter receiver attached to the air exchange assembly. The air-exchange assembly contains an exhaust tube with an open end and a closed end, two wings on opposite sides of the exhaust tube, and an intake check valve and an exhaust check valve inside the exhaust tube. The first replaceable filter surrounds the filter receiver; and the second replaceable filter is inside the filter receiver. Several apertures and the check valves are strategically disposed in the exhaust tube to achieve optimal air filtration and avoid contamination of a user's exhaust.

Devices and methods for treating respiratory problems of a subject, such as those related to sleep apnea, are presented herein. An implementation of a device may be configured to provide a measured vertical dimension of occlusion (VDO) and/or mandibular advancement in a subject. Methods for treating a subject through the use of the device may include systematically increasing and/or decreasing the measured VDO provided by the device.

The interchangeable mouth shields disclosed herein include a lip-anterior portion and teeth tray that can be releasably coupled together. The lip-anterior portion includes a panel positioned anterior to a lip shield. The panel can be customized to be different shapes and have decorative features. The interchangeable mouth shield includes a vent enabling a user to breathing through the interchangeable mouth shield during use. The teeth tray can be selectively flavored.

Embodiments of the present disclosure describe a mouth guard having a multiple chamber air channel allowing the user to mouth breathe during use. The air channel includes a forward air chamber and a pair of rear chambers. A support structure forms a divide between the pair of rear chambers with the front air chamber being generally unobstructed. The support structure may be relatively narrow and positioned rearward of an upper lingual ridge of the mouth guard.

A decorative plate is provided to removably engage a mouth guard to selectively change its appearance. The decorative plate may include a decorative display on its forward surface to provide the mouth guard with a desired, decorative appearance. In another embodiment, a decorative display member is positioned between a rearward surface of the decorative plate and a forward surface of the mouth guard. The decorative plate may be transparent in such embodiments so that the decorative display member is visible through the forward surface of the decorative plate. Various mounting brackets allow the decorative plate to be removably secured with mouth guards of various designs.

A cardiorespiratory fitness optimizer apparatus includes a mouthpiece and a valve assembly. The mouthpiece includes lower and upper tooth beds and an anterior manifold. The manifold terminates anteriorly at a centralized valve assembly interface and includes at least one air-letting aperture. The valve assembly is matable with the centralized valve assembly interface and includes an adjustable aperture. The user is able to adjust the aperture for increasing and decreasing airflow resistance therethrough for optimizing cardiorespiratory fitness. The cardiorespiratory fitness optimizer apparatus may include at least one sensor for sensing airflow activity within the valve assembly and communicating data relating to the airflow activity to an external device for displaying human readable output relating to the airflow activity upon the external device. The valve assembly is removable from the mouthpiece and replaceable with a plug element for maintaining anterior formations of the mouthpiece when the valve assembly is removed.
