【摘要】 目的探讨改良型治疗性义齿在颞下颌关节紊乱综合征患者咬合重建中的应用。方法使用改良型治疗性义齿对20例牙列缺损伴有颞下颌关节区器质性病变的患者进行咬合重建,分别在使用治疗性义齿期间及更换最终修复体后调查患者的主观感觉,检查临床症状,并采用Friction颞下颌关节紊乱指数(CMI)进行评估,采用SPSS17.0软件进行统计分析。结果患者佩戴治疗性义齿1个月后,关节区症状缓解有效率达到100%;佩戴最终修复体后,关节区舒适性以及修复体使用方面均能达到满意的疗效;CMI较治疗前明显下降(P<0.05)。结论对于牙列缺损伴有颞下颌关节紊乱综合征(骨关节病)的患者,改良型治疗性义齿在咬合重建过程中可获得理想的疗效。更多还原

【Abstract】 Objective This study aims to study the effect of the improved partial denture treatment in the rehabilitation of patients with temporomandibular joint disorders(TMD).Methods Twenty middle-aged and old patients suffering from osteoarthrosis were treated with the improved partial denture treatment.These patients were followed up during the partial denture treatment and after the rehabilitation.Both the clinical symptoms and Fricton’s craniomandibular index were used to evaluate the clinical effects.Data were analyzed using SPSS17.0.Results The effective rate reached 100% when the patients wore partial dentures for 1 month.All of the 20 patients were comfortable with temporomandibular joint,and they expressed ultimate satisfaction with the denture.The Fricton indexes of 20 patients decreased significantly after the treatment(P<0.05).Conclusion Partial denture treatment is an ideal method in rehabilitation for patients with TMD(osteoarthrosis) and dentition defect.更多还原
