垫合并透明质酸钠关节腔注射治疗TMD的初步临床研究

Clinical Study of the Treatment on TMD Patients by Splint and HA Joint Cavity Injection.

目的 :观察牙合垫对于治疗TMD的疗效。关节腔内药物注射治疗对于牙合垫治疗的影响。方法 :记录TMD病人口内牙合情况及咀嚼习惯 ,取模 ,记录并转移颌位关系。然后在模型上制作稳定型及诱导型牙合垫 ,戴入患者口内。部分患者同时进行药物注射治疗。通过短期随访观察疗效。结果 :1)单纯采用牙合垫治疗的患者中 ,70 .3%的TMD症状都有不同程度的好转。 2 )采用牙合垫和药物共同治疗的患者 ,其效果比单纯用牙合垫治疗效果好 (89.7% /70 .3% )。结论 :1)牙合垫治疗TMD是一种较为有效的方法。 2 )

Objective: To investigate the effect of splint therapy on TMD, and evaluate the effect of the injection of sodium hyaluronate into TMJ combined with splint therapy. Methods: The mastication and articulation habits, the condition of teeth and occlusion of TMD patients were recorded, and impressions were made, then jaw relationship were transferred into articulators .After that, cast wax patterns into heat-curing resin. Put these stabilization and repositioning splints into patients' mouths and ground them properly. Some patients received the therapy of sodium hyaluronate injection simultaneously. Results: 1) It was found that the major syndromes of TMD were alleviated in 70.3% of those who only received the treatment with splint , and that 2) those who also underwent injection treatment showed a better result (89.7%/70.3%). Conclusions: 1) Splint is an effective and conservative treatment modality for TMD. 2) Splint and sodium hyaluronate maybe have cooperation effects on TMD.
