**2.1 Study design**

A prospective study of 61 clinical cases of TMD with chronic pain (47 women and 14 men) was carried out. We have identified signs of TMJ recurrence in 92% of clinical cases. Of these, 75% complained of TMJ dysfunction and symptoms of chronic pain syndrome, and 25% of TMJ dysfunction. Against the background of the pain syndrome, phenomenological dysfunctions masked by complaints of other problems were revealed. Patients were observed for 2 years (5 points of observation): at the time of treatment; in 6 months; 1 year; 1 year and 6 months; and 2 years.
