The present invention relates to devices, systems and methods for detecting disturbances that may occur during the sleep of a subject.

A method, user interface and system for detecting and monitoring development of a dental condition. In particular, detecting and monitoring such a development by comparing digital 3D representations of the patient's set of teeth recorded at a first and a second point in time. For example, determining tooth movement for at least one tooth between the first and second point in time based on derived distances.

An environment control device includes a determination unit and a supply unit. The determination unit determines the type of symptom that disturbs sleep of a sleeper. The supply unit supplies the sleeper with a stimulus that reduces the symptom, according to the type of the symptom, disturbing the sleep, determined by the determination unit. The symptom includes at least snoring, and the determination unit determines whether the snoring is due to nasal congestion or due to constriction of the throat.

Enclosed are embodiments for diagnosis and monitoring of bruxism using earbud motion sensors. In an embodiment, a method comprises: receiving, with at least one processor, a signal derived from a motion sensor in an earbud, wherein the signal is captured while the earbud is inserted in an ear of a user; segmenting, with the at least one processor, the signal into segments; extracting, with the at least one processor, features from the segments; classifying, with the at least one processor, the features; and determining, with the at least one processor, that orofacial activity is predicted based on the classifying.

The present invention is method and a device to detect and treat Bruxism through a combination of muscle and brain sensors detecting sensors and providing a set of biofeedbacks to stop grinding while preventing habituation to biofeedbacks. The frequency and phase of the rhythmic grinding pattern of a Bruxer is identified and a biofeedback with the same frequency but different phase is applied on the user to stop grinding without waking the user from a sleep.

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.

Disclosed herein are system, method and/or device embodiments for using a wireless mouthguard with pressure sensors for measuring bite compression forces generated by a bruxism patient during sleep. A system comprises a mouthguard and a microelectromechanical system (MEMS) coupled to a portion of the mouthguard covering an axial plane of a tooth. The MEMS comprises an antenna, a capacitive sensor, a microcontroller, and a power supply. The sensor generates sensor signals corresponding to a force generated by a mouthguard wearer's bite. The MEMS may then transmit data describing the wearer's bite force over a period of time to an external computing device for display and analysis.

A system, method and appliance provides sleep-related disorder data collection, assessment, and visual representation. The appliance may be configured to be worn during a sleep cycle of an individual and may include or be operatively connected to various sensors that collect physiological data of the individual during the sleep cycle. Aspects of the system are configured to correlate data obtained from various sensors/data sources during an individual's sleep cycle, determine relevant events associated with sleep-related disorders based on the obtained data, provide summaries and information about the determined relevant events, and generate and provide dynamic visualizations of the individual's anatomy corresponding to the determined relevant events. A dynamic visualization may include a 3D model of the individual's airway and mandibular anatomy that, when played back, morphs to represent dynamics of the individual's anatomy during the relevant event.

The present intraoral sensing system which is configured to sense a biological information using a sensor module installed in an oral cavity, including: a sensor module installed in an oral cavity of a patient and configured to store data acquired when the biological information is sensed; a storage configured to acquire the data and an identification information of the patient stored by the sensor module, associate the acquired data with the identification information of the patient, and store the association; a terminal apparatus for a dentist configured to analyze the data stored in the storage for each of the identification information of the patient; and a terminal apparatus for a doctor configured to acquire the data associated with a patient who has a developed disease among the data of patients stored in the storage, from the terminal apparatus for a dentist.
