Diagnosis of bruxism based on piezoelentric sensor and remote communication

Active materials are capable of responding in a controlled way to different external physical or chemical stimuli by changing some of their properties. These materials can be used to design and develop sensors, actuators and multifunctional systems with a large number of applications for developing medical devices (for both surgery and implants). On the other hand Bruxism is a health problem consisting in grinding or tightly clenching the upper and lower teeth. Both the grinding and sliding lead to wear of the teeth and produce a noise during the night that is sufficiently loud to disturb the sleep of anyone sharing the bedroom. The tension produced causes problems in the muscles, tissues and other structures surrounding the jaw, ear pain, headaches, lesions to the teeth and disorders in the jaw joints. For an early, rapid, effective and economical diagnosis of bruxism, we propose the use of instrumented splints, based on the use of active materials, to detect and record the intensity and duration of interdental pressure episodes. This paper sets out the design, manufacture and testing of an instrumented splint for diagnosing bruxism. The system stands out for its use of piezoelectric polymeric sensors which, because of their reduced thickness, do not cause any alteration to the patient¿s bite. It lets a quantitative assessment of intraoral pressure be made and bruxism behaviour be diagnosed at an early stage, so as to being able to programme corrective actions before irreversible dental wear appears. The first trials performed served to demonstrate the feasibility of the system, which also includes wireless communication capabilities for telemedicine tasks.
