AbstractThe purpose of this study was to evaluate, through computerized electrosonography, the effectiveness of interocclusal appliance therapy, used by patients with temporomandibular disorders. Twenty two patients, male and female, ages between 18 and 53 years old, with temporomandibular disorders, were examinated and treated. The electrosonographic evaluations were carried out before the beginning of the treatment and 90, 120, 150 days after using the interocclusal appliance. It is important to emphasize that these appliances received canine guidance and group function modification at the 90th and 120th day, respectively. The collected informations were submitted to statistical analysis of polinomial regression, and revealed had a significant increase in joint sounds frequency in the right TMJ.
