Objective: To evaluate the effect of wireless
biofeedback therapy on bruxism. Methods: Fifteen bruxiers participated to be
treated by this therapy. The abnormal movements of teeth during sleep were
monitored by a maxillary splint with an electric resistance strain gauge.
Meanwhile, the receiver device recorded these details and analyzed the data, including
the value of the biting force, occurring time and duration. If the value of
biting force or duration exceeds the threshold, a vibrating device like a
watch will alert the patient to relax the masticatory muscles and nervous
system to stop the abnormal grinding or clenching. Data were recorded during
8 hours’ sleep and analyzed after the 12 weeks’ treatment and 24 weeks’
treatment. Results: The average episodes of bruxism have declined from (10.60 ±
1.23) to (6.60 ± 0.75) after 12 weeks’ treatment (p < 0.05), and the average duration of bruxism events was
reduced from (13.2 ± 0.74) s to (6.50 ± 0.40) s (p < 0.05). The average episodes of bruxism have declined to
(3.80 ± 0.64) after 24 weeks’ treatment, and
the average duration of bruxism events was reduced to (3.37 ± 0.34) s (p < 0.05). Conclusions: The results
suggest that biofeedback therapy can be effective for bruxism treatment.
