A mouthguard according to an embodiment of the present disclosure includes a pair of spaced lateral bite wings, a conduit defining an air channel extending between forward portions of the lateral bite wings, and a lip shield member and/or a flange disposed around and extending radially outward with respect to a forward end of the conduit. The conduit is tapered inward from its forward end toward its rearward end, and defines an incisor engaging surface proximate the rearward end of the conduit, and a lip engaging surface between the incisor engaging surface and the forward end of the conduit.

A mouth piece removal tool. The mouthpiece removal tool includes an elongated handle having a first end opposite a second end. A first hook extends perpendicular from the second end of the elongated handle. The first hook includes a pointed tip curving upwards.

A protective sports helmet that includes an energy attenuating faceguard connection system, which includes at least one connector that secures the faceguard to the helmet shell without a connection point in the shell's brow region. The lack of a brow region connection point results in a gap or clearance between the faceguard and the shell that has a functional interplay with the connector upon an impact to the faceguard. In general terms, when a substantially on-center impact to the faceguard occurs, the faceguard is displaced towards the shell and the connector bracket flexes outward relative to the helmet shell to help dissipate impact energy.

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.

A mouth guard senses impact forces and determines if the forces exceed an impact threshold. If so, the mouth guard notifies the user of the risk for injury by haptic feedback, vibratory feedback, and/or audible feedback. The mouth guard system may also remotely communicate the status of risk and the potential injury. The mouth guard uses a local memory device to store impact thresholds based on personal biometric information obtained from the user and compares the sensed forces relative to those threshold values. The mouth guard and its electrical components on the printed circuit board are custom manufactured for the user such that the mouth guard provides a comfortable and reliable fit, while ensuring exceptional performance.

A composite material which is elastic, which exhibits a resistive load under deformation which increases with the rate of deformation, which is unfoamed or foamed, comminuted or uncomminuted and which comprises i) a first polymer-based elastic material and ii) a second polymer-based material, different from i), which exhibits dilatancy in the absence of i) wherein ii) is entrapped in a solid matrix of i), the composite material being unfoamed or, when foamed, preparable by incorporating ii) with i) prior to foaming.

Various examples are provided for intelligent mouthguards that can be used in fitness and sport activities. In one example, an intelligent mouthguard system includes a mouthguard including sensors and an internal module in communication with the sensors. The sensors can include a nine-axis inertial sensor comprising a three-axis magnetometer, a three-axis accelerometer and a three-axis gyroscope. The three-axis magnetometer can provide a reference plane in relation to the earth's magnetic field for the three-axis accelerometer and the three-axis gyroscope. The internal module can provide sensor data to an external processing unit when located in an oral cavity.

A mouth guard, or wearable device, senses impact forces, calculates risk factors for injury, and displays status of risk and potential injury. A mouth guard may be used to identify, treat and prevent exacerbating brain injury. A wearable device can be programmed with biometric data to better calculate and anticipate impact thresholds and more precisely predict and prevent injury.

A mouth guard that can be used with elastic band in place on braces provided. In one example, a mouth guard for protecting teeth during athletic activities is provided that includes a generally u-shaped base coupled to inner and outer flanges to form a teeth receiving pocket. A first slot is formed through a left side the outer flange and open though a top of the outer flange. A second slot is formed through a right side the outer flange and open though a top of the outer flange.
