Objective  To compare efficacy of stable occlusal pad and repositioning occlusal pad in the treatment of patients with temporomandibular joint disorder syndrome.

  Methods  A total of 65 patients with temporomandibular joint disorder syndrome treated by occlusal pad were divided into stable occlusal pad group (n=35) and repositioning occlusal pad group (n=30). Clinical efficacy was compared between two groups.

  Results  After treatment, the incidence rate of joint bounce and VAS score in both groups reduced significantly compared with treatment before (P < 0.05). There was no significant difference in the incidence rate of joint bounce after treatment between the two groups (P>0.05), but the VAS score after treatment in stable occlusal pad group was significantly lower than that in repositioning occlusal pad group (P < 0.05).

  Conclusion  Both stable occlusal pad and repositioning occlusal pad can effectively treat patients with temporomandibular joint disorder syndrome, and repositioning occlusal pad is often used to treat the anterior displacement of the restorable disc. In the treatment of arthralgia, the effect of stable occlusal pad is more ideal.
