开张式双垫与塑料垫治疗磨牙症的对比研究

To evaluate the treatment effects of bruxism by using tensile spring occlusal splint and plastic occlusal splint

目的:比较开张式双垫在治疗磨牙症中与塑料垫的临床疗效。方法:分别用自制的开张式双垫与塑料牙合垫对48例磨牙症患者进行治疗,随访9个月。统计治疗结束1个月和9个月时的停止磨牙病例和平均减少的磨牙时间。结果:戴用1个月停止磨牙病例数比为6:12,戴用9个月时停止磨牙病例数比为10:21。其差异具有显著性(P<0.01)。结论:开张式双垫治疗磨牙症优于塑料垫。

Objective： To compact the clinical treatment effect of bruxism by using tensile spring occlusal splint and plastic Occlusal splint. Method： 48patients of bruxism were treated with the tensile spring occlusal splint.and plastic Oc- clusal splint, 9month was follow up.The patients who stop teech grinding and times which less than begin remedy were cal- culated by the one month and by nine month respectively. Result： In one month , the teeth grinding stopped in 6 cases to 12 cases by using plastic Occlusal splint and tensile spring occlusal splint,in nine month,which is in 10 cases to 21 cases; and there is remarkable difference between the two of kinds methods （P 〈0.01）. Conclusion： the tensile spring occlusal splint was more effective than plastic Occlusal splint in treating bruxism.
