RESUMEN
Objective: To observe the clinical effects of upper articular cavity injection with hyaluronate(HA) combined with Twinblock in the treatment of temporomandibular joint(TMJ) clicks. Methods: 60 patients with TMJ clicks were divided into 3 groups(n = 20) and were treated by articular cavity injection combined with Twin-block(group 1),Twin-block only(group 2) and injection of sodium hyaluronate gel(group 3) respectively. The effects were evaluated and compared before and after treatment by both doctors and patients. Results: The effective rate of group 1,2 and 3 was 95％,and 65％ respectively(P ＜ 0. 05). After treatment the TMJ clicks were almost dispeared in group 1,remitted in group 2 and slightly remitted in group 3. Conclusion: The articular cavity injection of HA combined with Twin-block is more effective in the treatment of TMJ clicks than Twin-block or articular cavity injection of HA.
