Example embodiments of the present invention provide a multi-function oral appliance, comprising an elastomeric polymer, a hard non-elastic polymer, or a combination of the two fused together; formed using 3D printing or vacuum-forming; configured to engage all or part of the bottom and top teeth such that the lower jaw is advanced, e.g., 8 mm, anterior to its habitual resting position and opened, e.g., 8 mm, from its habitual resting position when the appliance is applied; and configured such that, e.g., 90%, or more, of airflow through the mouth is blocked by the appliance. In some embodiments, the appliance is configured to include gel-wells in the interior of the appliance.

An accessory device and an immobilization system including the device are provided for positioning at least a portion of a patient's body relative to an immobilization device including a low temperature thermoplastic sheet. The accessory device may include a patient fixation portion and a lock portion. The patient fixation portion is attached to or inserted in the patient during use. The lock portion may extend distally from the patient fixation portion generally along a lock portion axis. The lock portion includes a shape, surface feature, or configuration, such that the low temperature thermoplastic sheet may be conformed to the outer surface of the lock portion of the accessory device, such that unintended separation of the accessory device from the low temperature thermoplastic sheet is prevented. Methods of forming the accessory device and immobilization system are also provided.

The diagnosed soft tissue or brain injury component of concussions is generally defined by the symptoms of the temporal lobe manifestations. However, there is an undiagnosed structural fractured component of concussions occurring within the jaw joint complex which is the focus of this invention. A precise imaging technique and the powerful 3D Cone beam scanning technology, together, have revealed fractures in temporal bones of the jaw joint space which supports the temporal lobe of the brain. These fractures are the results of the lower jaw impact forces that cause concussions and this mechanism account for a large percent of the concussions arising in sports and military operations. These fractures have never been considered, diagnosed, or treated in the management of concussions. Fracturing temporal bones in the jaw joint that supports the temporal lobe will certainly produce the symptoms of temporal lobe manifestations. With early detection, these fractures can be more rapidly healed, eliminating many temporal lobe symptoms of concussions. The device of the present invention reduces the risk of the lower jaw impact concussion and temporal bone fractures, while enhancing the ability to speak and orally communicate.

An Internet of Thing (IoT) device includes a body with a processor, a camera and a wireless transceiver coupled to the processor.

A mandibular advance advancement device generally indicated by the numeral 1. The mandibular advancement device 1 having a first member 2 and a second member 3. The first member 2 is configured to fit substantially over a portion of the teeth of the upper jaw of a user and the second member 3 is configured to fit substantially over a portion of the teeth of the lower jaw of the user. The mandibular advancement device 1 further has an engagement arrangement 4, configured to be engagable upon a forward manipulation of the lower jaw by the user, to maintain the lower jaw of the user in a predetermined protruding position relative to the upper jaw of the user and the natural biting position of the lower jaw.

A system for sensing true positive impacts may include a sensing device configured for secured coupling to a user. The sensing device may include a sensor configured for sensing accelerations of an impact and for generating a signal based on the impact. The sensing device may also include a control sensor for sensing when the sensing device is in position for sensing. The sensing device may also include a computer-readable storage medium having instructions stored thereon for receiving and capturing the signal from the sensor, and comparing first and second signals from the control sensor to determine if the signal is a true positive signal. The system may also include a processor for processing the instructions to capture the signal, perform the comparing, and identify the signal as a true positive signal. Method of sensing true positive impacts and of workload monitoring are also provided.

A photocurable composition includes a (meth)acrylic monomer component and a photopolymerization initiator, wherein an adhesive force of a cured product is less than or equal to 1.5 N, and a rupture elongation of the cured product is greater than or equal to 20%.

An Internet of Thing (IoT) device includes a body with a processor, a camera and a wireless transceiver coupled to the processor.

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.

The present disclosure relates to heat mouldable mouth guards, to methods for using the mouth guards, and to methods for producing the mouth guards. In certain embodiments, the present disclosure provides a heat mouldable mouth guard, the mouth guard comprising: an inner framework comprising a semi-rigid thermoplastic; and an outer layer comprising an elastomeric thermoplastic which has a melting temperature higher than the semi-rigid thermoplastic of the inner framework, wherein the outer layer substantially encapsulates the inner framework.
