Abstract: Objective: To analyze the effects of anterior repositioning splint on temporomandibular joint with intermittent locking. Methods: Thirty-four patients with disc intermittent locking were included. All of these patients wore anterior repositioning splints for 6 months and 6 months follow-by observation. Visual analogue scale (VAS), Fricton’s craniomandibular index, and mandible movement function test were used to evaluate the effectiveness of the anterior repositioning splint on temporomandibular joint with intermittent locking. Result: After the treatment, the VAS and Fricton’s craniomandibular index were significant decreased. The painless maximum opening gradually increased (P<0.05). There was no significant difference in protrusion excursion. The significant difference of lateral excursion was found and could be kept stable at the 3 and 6 months reexamination. Concluson: Anterior repositioning splint can be used as an effective way to treat patients with temporomandibular joint disc with intermittent locking.
