Development of bite guard for wireless monitoring of bruxism using pressure-sensitive polymer

A wireless pressure sensing bite guard has been developed for monitoring the progress of bruxism (teeth grinding during sleep); as well as for protecting the teeth from damages. For sensing the grinding event effectively in restricted space and hostile environment, a pressure sensitive polymer composite which is safe for intra oral applications has been fabricated and encapsulated into a conventional bite guard. Also encapsulated was a microcontroller-based electronic circuit which was built in-house for data collection and transmission. A low power approach was configured to maximize the working life-time of the device to several months. The device can provide real-time tooth grinding profile through wireless communication. This device is anticipated to be a useful tool for understanding and treating bruxism
