Abstract：Objective This study aimed to observe the clinical effect of the stabilized occlusal plate in the treatment of temporomandibular joint disorders (TMD). Methods A quasi-experimental method was used in this study. From June 2018 to February 2020, 84 patients (9 males and 75 females, aged 16-70 [29.5±12.0] years old) with TMD were treated in the Department of Stomatology of the Affiliated Hospital of Gansu Medical College. They were treated with stable occlusal plate for 3 months. The efficacy, visual analogue scale (VAS), opening degree, and joint snap before and after treatment were compared. Results After the 84 patients with temporomandibular disorder received treatment by wearing a stable occlusal plate for 3 months, 11 showed an obvious effect, 49 had an effect, 18 had no effect, and 6 had aggravated conditions; the total effective rate reached 71.4% (60/84). In terms of before treatment, 1 week after treatment, 1 month after treatment, 2 months after treatment, and 3 months after treatment, the VAS ratings for the 84 patients were 7.9±0.8, 6.6±1.0, 5.7±1.2, 4.8±0.8, and 3.8±1.1, respectively; the openness was (27.1±2.3) mm, (31.3±1.7) mm, (39.0±2.5) mm, (43.5±2.1) mm, and (49.3±1.3) mm, respectively; and the joint clicking occurrence rates were 76.2% (64/84),75.0% (63/84), 70.2% (59/84), 72.6% (61/84), and 69.0% (58/84), respectively. There was a difference between the VAS value from the analysis and comparison of variance and each stage of openness (F=27.06, 14.56, all P values <0.001); the difference in the proportion of number of joint clicking case in each stage was not statistically significant (χ2=1.59, P=0.748). Conclusion The stable occlusal plate has a good therapeutic effect on TMD and obvious therapeutic effect on improving joint pain and restoring opening. It also shows a certain curative effect on alleviating joint snap.
