Smart diagnostic mouth guard system
Various examples are provided for a smart mouth guard for diagnosis, quantification, and/or management of e.g., bruxism. In one example, among others, a diagnostic mouth guard includes a plurality of pressure sensors and processing circuitry configured to provide pressure sensor data to an external processing unit when located in an oral cavity. The diagnostic mouth guard may also include temperature, pH and/or inertia sensors. In another example, a system includes the diagnostic mouth guard and the external processing unit such as, e.g., a smart phone, table or computer. The diagnostic mouth guard can communicate with the external processing unit over a wireless channel.
1. A diagnostic mouth guard, comprising:
