Nov. 2016 to 30th. Sep. 2017 were conducted. The subjects were devided into three groups: control group (34 patients treated without occlusal splints), S-S group (31 patients treated with stabilization splint) R-A group (16 patients treated with resilient appliance). The pain intensity using VAS(Visual Analog Scale) and MMO(maximum mouth opening) were evaluated every week. Results: The improvement of the pain intensity and MMO in the S-S group and the R-A group compared with the control group was noted (p<0.05). Conclusion: The occlusal splints are effective to treat on acute advanced disc displacement without reduction of temporomandibular joint. Especially resilient appliance is recommended to treat on acute advanced disc displacement without reduction of temporomandibular joint in short period.
