The Use of Biofeedback Devices in the Treatment of Bruxism
The results of pilot investigations recently completed at the UCLA TMJ Clinic suggest that the treatment and investigation of self-destructive oral habits may be facilitated by the use of portable muscle hyperactivity devices worn by patients (Figure I). The need for these devices is supported by considerable evidence suggesting that abnormal oral habits such as bruxism may cause or contribute to excessive tooth wear, trauma from occlusion, and TMJ pain and dysfunction. Treatment and investigation of these problems has been difficult because the habits involved arc usually performed unconsciously; thus patients are unable to report the occurrence, nature, or frequency of their habit. The present investigators have developed a portable muscle biofeedback unit that delivers an audible “warning” tone should the patient clench or grind his teeth (Figure 2).
