Abstract: Objective: To compare the effects of stabilization splint and reposition splint on the treatment of patients with temporomandibular joint disorders. Methods: Thirty-two patients with temporomandibular disorders were selected, in which 18 patients were treated with stabilization splint and 14 patients were treated with repositioning splint, respectively. Comparative analysis was performed before, 3 months, 6 months, and 12 months after treatment for patients on the joint elastic ring and pain index (VAS). Results: After treatment, joint elastic ring and arthralgia in the two groups were significantly improved (P<0.05). No significant difference on the joint ring was found between two groups. The VAS of stabilization splint group was lower than that of reposition splint group and the differences was statistically significant (P<0.05). Conclusion: Two occlusal splints can effectively treat temporomandibular joint disorders. The repositioning splint is mainly used for anterior disc displacement with reduction and the stabilization splint is better for joint pain.
