【摘要】 目的:观察咬合板和透明质酸钠(SH)关节腔注射介入治疗颞下颌关节不可复性盘前移位的临床效果。方法:将96例颞下颌关节不可复性盘前移位患者随机分为单纯咬合板组(单纯戴用咬合板)、单纯SH介入治疗组(单纯关节腔内介入治疗)和咬合板联合介入治疗组,每组32例。治疗3个月后,比较3组患者在开口度和疼痛方面的疗效。结果:治疗3个月后,3组的开口度均增加,疼痛指数均降低,差异有统计学意义(P<0.01)。治疗3个月后,咬合板联合介入组的开口度改变值大于单纯咬合板组和单纯SH介入治疗组,咬合板联合介入组和单纯SH介入治疗组的疼痛缓解程度均大于单纯咬合板组,差异均有统计学意义(P<0.001)。结论:联合治疗疗效明显优于单纯戴咬合板或单纯介入治疗,SH在缓解疼痛方面的疗效优于咬合板治疗。更多还原

【Abstract】 Objective:To investigate the clinical effect of biteplate and interventional treatment with sodium hyaluronate on anterior disc displacement without reduction.Methods:Ninety-six patients with anterior disc displacement without reduction were divided into three groups (32 patients in each group),group A (biteplate treatment only),group B (interventional treatment only) and group C (combination of biteplate and interventional treatment).Three months after treatment,the pain index and maximal mouth opening were compared between groups.Results:After treatment,the maximal mouth opening was increased and the pain index was decreased in patients of three groups.The improvement was statistically significant (P < 0.01).The change of maximal mouth opening was bigger in combined group than that of biteplate treatment only and interventional treatment only groups.The pain index was significantly lower in combined group and interventional treatment only group than that of biteplate treatment only group (P < 0.001).Conclusion:The clinical effect is obviously better in patients of combination group than that of biteplate treatment only group and interventional treatment only group.The clinical effect of sodium hyaluronate on alleviating pain is better than that of biteplate treatment.更多还原
