The effect of occlusal splint on relieving the symptoms of adolescent patients with TMD

目的:考察垫对青少年颞下颌关节紊乱病患者临床症状的改善情况。方法:采用稳定性垫或再定位垫治疗71例颞下颌关节紊乱忠者,比较治疗前后张口度、颌面部疼痛和关节弹响的变化情况。结果:治疗组51例患者中疼痛34例,张口受限15例,疼痛伴张口受限14例,单纯性疼痛20例,治疗后疼痛及张口受限均得到缓解,缓解率为100%。治疗前疼痛指数和张口度分别为7.5±2.09和26.5±5.12mm,治疗后分别为2.4±1.58和40.1±5.03mm,差异均有显著性(P<0.05);关节弹响41例,治疗后18例弹响消失,16例弹响减轻。对照组中有2例弹响自行消失,3例疼痛自行缓解,其余无变化,差异有统计学意义(P<0.05)。结论:垫对颞下颌关节紊乱病患者的临床症状有显著缓解作用。

Objective： To observe the effects of occlusal splint on relieving the symptoms of adolescent patients with TMD. Methods： 71 patients with TMD were treated with stabilization splints or repositioning splints, then the change of opening distance, maxillofacial pain and joint noise were compared before and after treatment. Results： Among all the patients, totally 34 experienced pain, of which 14 experienced pain plus opening restriction, while the rest only had pain. 41 patients experienced joint noise. After treatment the symptoms was relieved. The joint noise of 18 patients disappeared, and 16 reduced. The pain index and opening distance before treatment were 7.5 ± 2.09 and 26.5 ± 5.12 mm respectively, after treatment they were 2.4 ± 1.58 and 40.1 ± 5.03mm, which was significantly different from pre-treatment（P〈0.05）, Conclusion： The occlusal splint can be employed to relieve the symptoms of TMD to some extent.
