[Applications of biofeedback in dental practice].

"Electromyographic biofeedback", or biological retroaction, used as a training process, concerns numerous medical specialties, and in a wider sense, to dentistry. Based on several studies, this article explains the various indications of this method in our discipline, stressing particularly the effect of electromyographic biofeedback in the treatment of cranio-mandibular disorders, emphasizing the different modes of application (in-patient or ambulatory). Acting at two levels, stress reduction and inducing relaxation of contracted muscles, electromyographic biofeedback occupies an excellent place in everyday practice. Finally, considering the results of their own study, of the particular type of relation instituted by the treatment and its role in the care and monitoring of the patient, the authors emphasize a major indication: the treatment of cranio-mandibular disorders of non-organic origin.
